## Foreword 1. Purpose

Marine Corps Reference Publication (MCRP) 2-15.3B, Reconnaissance Reports Guide, provides tactical reference material on the content and format of reconnaissance reports. It is intended as a reference aid for tactical field use and is based on information contained in numerous doctrinal publications available to Marines. This publication is intended to be used not as a replacement for those source publications, but as a handy compilation of important tactical information.

## 2. Scope

MCRP 2-15.3B contains reference material that is frequently used in the collection and reporting of information resulting from Marine groundreconnaissance operations. This publication was prepared primarily to assist reconnaissance patrol leaders and communicators functioning at the team level and the parent organization or supported unit to which the reconnaissance element may report. Leaders and staffs of supported organizations should also have knowledge of the contents of this manual so that they may have compatible reporting formats and, thereby, increased accuracy and consistency of reported information. This publication is in a loose-leaf format to better facilitate its use.

## General Information

1001.

General. The purpose of report formats is to provide information in a *standardized* format within or between units. Standardized formats simplify and speed the accurate, timely flow of reports from information collectors to information analysts. Formats help to minimize confusion and assist the generation of tempo. In modern warfare, one can expect to conduct operations as part of a joint or allied/coalition force; this makes the disciplined use of accepted formats a requirement.

1002.

Organization. A common listing of units of measurement is found in paragraph 1006. This paragraph lists codes for each unit of measurement that may be used throughout a particular report; these codes are common to all succeeding formats. Each individual report format included within this publication (Appendices A through U) is internally organized to provide a logical sequence for reporting the required information. The information comprising the report is organized to support analysis and ensure completeness of data. The information is arranged as a series of fields; each field contains adequate space for reporting in sufficient detail. The formats also support the use of brevity codes, which minimize transmission time and thereby increase the probability of survival for the reconnaissance patrol.

1003.

Use. The formats in Appendices A through U are intended for use by the information collector for transmission of reports to the organization requiring that information. These reports may be used to provide initial information on specific objectives or areas. They may also be used to confirm or amplify information that is already known or reported.

## 2 Reports Format Mcrp 2-15.3B Reconnaissance Reports

1004.

Training. Proper use of report formats requires training and practice. The reconnaissance team leader is responsible for the proper collection and reporting of information. That responsibility includes proper training and rehearsal of message reporting using these formats. To save valuable space in this field guide, completed examples of report formats have not been included. Detailed information on how to properly acquire, record, and report the required information may be found at the resident basic reconnaissance courses or within reconnaissance units. Proficiency should be developed through constant practice in collecting, formatting, sending, and receiving reports.

1005.

Technological Advances. The acquisition and fielding of communications devices such as the digital automated communications terminal (DACT) and other similar systems will greatly increase the speed of the drafting and transmission of tactical reports. These devices will contain preformatted message menus and digital burst transmission features to increase accuracy, dependability, and team survivability, but they probably will not eliminate the requirement to maintain voice or continuous wave (CW) transmission capability. Aside from backup capability in the event of equipment failure, it may also be necessary to communicate nondigitally with allied or coalition partners.

## 1006. Units Of Measurement

a. General. Line ALPHA of all of the appended reports indicates, through inclusion of relevant number codes, which units of measurement are referred to in the report text. Selections of units of measurement are made from the list below. Once designated in line ALPHA, the units of measurement are used consistently throughout that particular report.

| Units of Measurement                    |   Number Code |
|-----------------------------------------|---------------|
| Measurements of distance or dimension:  |               |
| Meters                                  |             1 |
| Yards                                   |             2 |
| Feet                                    |             3 |
| Measurements of declination or bearing: |               |
| Degrees magnetic                        |             4 |
| Mils magnetic                           |             5 |
| Measurements of speed:                  |               |
| Kilometers per hour                     |             6 |
| Miles per hour                          |             7 |
| Knots (nautical miles per hour)         |             8 |
| Measurements of temperature (degrees):  |               |
| Degrees centigrade                      |             9 |
| Degrees Fahrenheit                      |            10 |

b.

Usage. Only those number codes that correspond to units of measurement that are actually used in the report are included in line ALPHA. Only one unit of measurement for each type of measurement is specifiedfor example, for measurements of dimension or distance, either the code 1 (meters), 2 (yards), or 3 (feet) can be used; it defeats the purpose of using the code to refer to more than one of the same type of measurement within a single report. For instance, if line AL- PHA of a surf observation report (SURFREP) specifies that code 3

## 4 Reports Format Mcrp 2-15.3B Reconnaissance Reports

(feet) is used as the unit of measurement, all measurements within that report are given in feet, not in meters or yards. This keeps measurement-unit use consistent throughout the report. If it is essential to use units of measurement that are different from those specified, these units of measurement must be stated specifically each time they are used in the text.

## 1007. General Communications Information

a.

Primary Means of Communication. Radio is the primary means of communication for a reconnaissance patrol. Because reconnaissance patrols may operate at great distances from friendly positions, it is important that reconnaissance patrol leaders know the planning range of their radios and how to increase this range by using fieldexpedient antennas. Because of the electronic signature emitted by transmitting radios, it is imperative that reconnaissance patrols maintain the highest degree of communications security by shortening radio transmission lengths, by properly using the communications-electronics operating instructions (CEOI) and authorized brevity codes, by encrypting transmissions, and by using directional antennas to minimize detection.

b. Planning Range. The planning ranges for various radios now in use within the Marine Corps are:

Communications Equipment

HF

Up to 1,600 km
Note:  Actual ranges are determined by atmospherics, antenna, and transmitter power.

c. Morse Code. Morse code, or CW transmission, is a fairly reli-
able means of long-distance communication, but it has some
drawbacks.  Because the radio transmits continuously to send
CW, it is more susceptible to direction finding. Using CW trans-
mission also requires a considerable amount of training to be able
to send and receive messages, even at the reduced standard of six
words per minute for reconnaissance personnel. However, short
CW transmissions using brevity codes can be a highly reliable
means of getting some important messages through when other
means fail. CW transmission requires little power to send strong
messages over a great distance.  It is also highly effective in pow-
ering through interference or jamming signals.

## 6 Reports Format Mcrp 2-15.3B Reconnaissance Reports Guide

Appendix V contains a  Morse code chart to assist in refreshing the memory of the radio operator for those situations requiring CW capability. For more information on CW transmissions, see Fleet Marine Force manual (FMFM) 3-30, *Communications*.

d.

Brevity Codes. Use of brevity codes can help to reduce transmission times and thereby increase the survivability of the reconnaissance team. The key to brevity-code use is strict control of codes. Control is exercised not only by clearly establishing procedures for use and actual codes, but also by limiting distribution to those who have a clear need. Codes should be rotated periodically to prevent unauthorized use or interception. An example of a locally produced brevity code matrix can be found in Appendix W.

e.

Field-Expedient Antennas. Field-expedient antennas are temporary antennas designed and constructed by the user to increase the range of tactical radio sets. Field-expedient antennas provide increased signal efficiency through the use of an antenna that is specifically designed for the operating frequency in use, through elevation of the antenna above ground, or by concentrating the radiated signal along a given direction. Field-expedient antennas are easily constructed from MD-1-type communications wire (or a similar substitute, such as copper wire) by using poles or trees to provide support. The most important considerations are site location and physical location of the radio set within the site, whatever type of antenna is used.

## F. Basic Antenna Types

| Transmission Direction   | Antenna Type          |
|--------------------------|-----------------------|
| Omnidirectional          | Whip                  |
| Bidirectional            | Doublet               |
| Unidirectional           | Vertical half rhombic |

g.

Examples of Field-Expedient Antennas. For more information on field-expedient antennas, including examples of different types of field-expedient antennas and directions for their construction, see Fleet Marine Force reference publication (FMFRP) 3-34, Field Antenna Handbook (currently under revision as MCRP 6-22D).

h.

Reporting Occasions. A team leader is responsible for reporting to his higher echelon of command. Local commanders assist this effort by establishing reporting windows for the transmission of routine traffic or routine reports, such as situation reports (SITREPs). Local commanders also establish priority reporting criteria for each committed team based on that team's information requirements (IRs), which are issued in the team's mission statement. Normally, teams do not maintain constant radio communication while moving and sometimes while in observation posts, but they do monitor and transmit messages during the established windows. The parent unit, however, establishes around-the-clock radio watches over primary and alternate nets so that teams can communicate immediately if necessary.

## Terrain Reconnaissance For Aircraft Landing Zone (Alz) Report (Alzrep)

CHARLIE
Location. This information is reported and numbered by
using subparagraphs as listed below.
1. This subparagraph reports, by grid references, the extremities of the tentative location of the ALZ, prefixed by the grid zone designators when there is any possibility of uncertainty about the map being used.
2. This subparagraph reports the grid reference of the location of the datum point (DP). The DP is the point from which all bearings and distances of any reference points (e.g., an obstacle) can be located. It should be possible
for the DP to be accurately plotted and identified for use as a convenient point from which to measure and locate specific points on the ALZ.

Notes:

1.
Lines need not be transmitted if they are either not
known or not required. NC (no change) can be used to confirm information given in the reconnaissance briefing.
2.
In the event that ground reconnaissance of an existing
airfield is necessary, the above format will be supplemented with prebriefed IRs for reporting the usefulness of existing facilities and their vulnerability to destruction by occupying enemy forces.

D
previously determined to be a beach exit but as of this time is unusable for any type of exit from the beach.
3. Width of the beach exit, using the unit of measurement
designated in line ALPHA.
4. Trafficability of the beach exit if it can support vehicle
traffic. Use the letter code from line HOTEL.
HOTEL
Beach Trafficability. This line provides a general description of the beach's ability to support vehicle traffic. The following letter code will be used to report this information.
Beach Trafficability
Letter Code
Firm. The beach will support
W
2-wheel-drive vehicles or 4- wheel-drive vehicles with trailers unless heavy continuous use is intended.
Moderate. The beach can be used
X
by 3- or 5-ton vehicles, which should be able to start from rest by using
all-wheel drive. Recommend
using beach matting/roadway.
MCRP 2-15.3B
 Reconnaissance Reports
Soft. Four-wheel-drive vehicles
Y
cannot start from rest but might
be able to cross the beach if already
on the move. Recommend using
beach matting/roadway.
Very Soft. The beach is impassable      Z
to wheeled vehicles, and tracked vehicles may experience difficulty. Use of beach matting/roadway is required.
Note: If there is a marked difference in the trafficability
along the beach, this must be reported. Use the same letter code and any previously coordinated method of location to designate where the beach trafficability changes, followed by the present trafficability code.
JULIET
Littoral Drift. Littoral drift is a current moving parallel
to the beach. This information is reported in the unit of measurement designated in line ALPHA. The velocity of the current is reported to the nearest one-tenth of a knot. Direction of the current is reported L (left) or R (right) as viewed from seaward, as if the recorder were a coxswain in a boat heading toward the beach. This information is reported in the following sequence:
1st.
Velocity of current to the nearest one-tenth of a
knot.
2nd. Direction of the current as viewed from
seaward L (left) or R (right).

3rd. DTG of when this information was recorded.

Note: One knot is equal to 100 feet (31 meters) of drift in
one minute. This information can be calculated by measuring the distance that an object floating in the water travels in one minute parallel to the beach. This method will also give the recorder the direction of the current.
KILO
Enemy. If the enemy has been observed or contacted,
state Y (yes) and submit a SPOTREP/SALUTE report separately. If no enemy has been observed, report NIL in this line of the report.
LIMA
Remarks. Any other information is provided that may be
critical to the accomplishment of an amphibious landing on the beach being reconnoitered. Requirements for information should be covered in the patrol's IRs.

## Confirmatory Beach Report (Conberep)

Begin this report with the subject line of the message and the serial number, followed by the code name and map sheet details as required.

ALPHA
Units of Measurement. See the table on page 3.
BRAVO
Offshore Obstructions. This line should include previously unknown offshore obstructions that show above the water at low tide. These are listed sequentially, and the following information for each obstacle is transmitted individually as shown here:
1st. Description of the obstacle.

2nd. Location of the obstacle, either by grid reference
or bearings and ranges from known landmarks that can be plotted on a map or chart.
CHARLIE
Littoral Drift. Littoral drift is a current moving generally
parallel to and adjacent to the shoreline. When it differs significantly in velocity or direction from earlier estimates, indicate the new velocity in knots to the nearest tenth of a knot. Direction of the current flow is expressed to the left or right. (See notes 1 and 2 later in this appendix.) This information is followed by the DTG of when this information was recorded.
DELTA
DP(s). These are fixed positions to which the sounding
lines are referenced. The existing situation will dictate whether one or more DPs will be required. DPs should be

## Reconnaissance Reports Mcrp 2-15.3B Reconnaissance Reports

designated by letters, for example, DP A, DP B, DP C,
and so on, as required. Each DP must be a "fixed"
position/point and should be reported by a grid reference (eight digits if possible) or by bearing and range from other known fixed positions/points that are represented on the maps or charts. These fixed points should be precoordinated before the team is inserted and should be assigned some sort of code designator.
ECHO
Sounding Interval. This is the difference between each
sounding on the sounding line. The sounding interval may
vary by particular units, specific conditions, or commander, amphibious task force (CATF) require- ments.

## Foxtrot Sounding Lines

1.
All sounding lines are numberedF1, F2, F3, and so
onand information relating to these sounding lines is
provided in five sections (A through E); each section reports different information that is pertinent to the individual sounding lines.

2.

The sounding line designation consists of three characters. The first character is the letter designating the DP to which the sounding line is being referenced. The second and third characters combine to form two-digit numerals that designate the sequential number of individual sounding lines; for example, A01-A/ALPHA designates the DP being referenced for this sounding line, and 01 designates the sequential number of the sounding line being reported from DP A/ALPHA.

3.

Sections A through E provide the following information, which is pertinent to that particular sounding line and is reported in the sequence listed in A through E.

A.

Locates the waterline at the time of the sounding (WLTS) in relation to the applicable DP and is expressed as bearing and range from the DP. The DP will always be on the bearing of the first sounding line.

B.

Indicates the bearing of the sounding line as viewed from seaward.

C.

Provides the DTG of when the sounding was taken. This information is important in adjusting the sounding to mean low water (MLW) when the chart is created. The month and year are not necessarily required.

D.

Indicates the distance (in the unit of measurement designated in line ALPHA) from WLTS to the back of the beach (BOB) and the vertical rise over this distance along the bearing of the sounding line. If the vertical rise cannot be measured, then the gradient should be estimated and reported by using the following letter codes:

Gradient
Letter Code

| Flatflatter than 1:120                             | V   |
|-----------------------------------------------------|-----|

| E.                                                  |     |
| Indicates each sounding to the nearest one-tenth    |     |
| meter or one-half foot, followed by the bottom com- |     |
| position, using the letter code in line HOTEL. The  |     |
| sounding must be reported in linear sequence begin- |     |
| ning from WLTS and working seaward.                 |     |

4.

For the second and subsequent lines, the report will show similar data in the same sequence, except that under the first subparagraph, WLTS
A
may be expressed/plotted by using any of the following:
A. The bearing and distance from WLTS of the previous sounding line.

-or-
B. The bearing and distance from the DP being used for that sounding line.

-or-
C. If any sounding line is to be based on a new DP, then the same procedure as in FOXTROT 1A is to be used.

GOLF
Underwater Obstacles. This paragraph is used to
indicate underwater obstacles relative to sounding lines by naming the type of obstacle, its location (use sounding line designation and distance from WLTS), depth of water over the obstacle, and its estimated size.
HOTEL
Beach Composition. This is a general description related
to the beach as a whole that is divided into two areas: the foreshore (from MLW to mean high water (MHW)) and the backshore (MHW to BOB). An assessment of underwater composition is provided, as required. The following letter codes should be used:
Beach Composition
 Letter Code
Mud
A
Clay
B
Sand (up to pinhead size)

C
Gravel/shingle (up to top-of-thumb size)
D
Pebbles (up to clenched fist size)
E
Cobbles (up to human head size)
F
Boulders (larger than human head size)
G
Coral
H
Other (describe briefly in this line)
J
If there is a marked variation in composition along the beach, this is to be reported, using code, by reference to designated sounding line numbers; for example, HOTEL 1.A08 to B02 E means that the foreshore from sounding line A08 to sounding line B02 is now composed of pebbles.

## Conberep Mcrp 2-15.3B Reconnaissance Reports

JULIET
Trafficability of the Beach. This is a general description
of the beach as a whole. Reports are provided on only two areas: the foreshore (portion of the beach between WLTS and MHW line) followed by the backshore (from the MHW line to the line of first permanent vegetation or BOB). This information will be reported by using these letter codes:
Trafficability Conditions
Letter Code
Firm. Can be used by 2-wheel-
W
drive vehicles and 4-wheel-drive vehicles with trailers unless heavy and continuous use is intended.
Moderate. Can be used by military
X
3- to 5-ton vehicles, which should be able to start from rest by using allwheel drive. Recommend that beach matting/roadway be used.
Soft. Four-wheel-drive vehicles
Y
cannot start from rest but might
be able to cross a soft patch if
already on the move. It is recommended that beach matting or roadway be used.
Very Soft. This is impassable to
Z
wheeled vehicles. Tracked vehicles
may experience difficulty. Beach matting/roadway is required.
Note: If there is a marked difference in trafficability along
the beach, this is to be reported in a similar manner to line HOTEL above. Foreshore trafficability can only be assessed above the WLTS. It must be clearly understood that a correct assessment of trafficability cannot be guaranteed, bearing in mind the conditions under which the team may be working. Allowances must be made for a high degree of error. The only way to get an accurate assessment of beach trafficability is to have the team return with soil samples that are properly cataloged and recorded.
KILO
Exits. This is a description of any new exits or exits that
have changed from the latest intelligence estimates. Each beach exit is listed and described individually. The exits are described by reporting the grid reference where the exit meets the BOB, followed by a description using the following letter codes:
Type of Beach Exit
Letter Code
Infantry. If the exit is usable by
A
infantry only, then the width of the exit is reported following the letter code.
Tracked Vehicles. If the exit is

NOVEMBER
Remarks. Any additional information relevant to this report can be included here. Any essential elements of information (EEIs) or other information requirements
(OIRs) should be stated in the patrol's operation order
(OPORD) and will come down from CATF and commander, landing force (CLF).

## Notes:

1. The term right or left always refers to the beach area as viewed from seaward, as if the reader of the report were a coxswain in a boat coming into the beach.

2. One knot equals approximately 31 meters or 100 feet per minute of movement. If the recorder were to toss an object into the water and measure how far it has moved in that current in one minute, he should be able to approximate the speed and the direction of that current.

3. If no change is found in the information already known, the relevant line or subparagraph of that line is transmitted with that line heading followed by NC (no change).

## Contact Report (Contacrep)

The CONTACREP, although not a standard report, is very useful for briefly and concisely reporting any enemy contact. It consolidates the most important IRs of the SITREP and the CASREP without wasting large amounts of transmission time in a rapidly evolving and tenuous situation. In such situations, the reconnaissance patrol leader must be able to concentrate all of his attention on resolving his patrol's present situation and continuing the mission, working out a plan to extract his patrol to a secure area, or effecting the evasion and escape (E&E) plan.

C**Call sign.** "(Receiver's call sign) this is (originator's call sign)."
O**Occurrence.** Describes the type of contact/what has happened. N**Needs.** States medical evacuation, emergency extraction, immediate suppression, reinforcement, resupply, and other needs.
TTime/Location. Indicates at what time the contact took place and
where. These coordinates do not need to be encrypted/shackled.
A**Actions Taken.** Describes what the patrol has done since the contact was made, for example, broken contact, E&E, or so on.
C**Casualties.** Reports friendly KIAs/WIAs and transmits kill numbers from the warning order/kill sheet to assist the medical evacuation when needed.
Note: The person transmitting the CONTACREP must be prepared to authenticate if operating over an uncovered net. This is especially the

Location. This line provides grid references of the beginning and end of the section of the river/estuary actually reconnoitered by the team.
CHARLIE
Main Channel. This information is reported in the following numbered sequence:
1.
Location. The grid reference of the entrance to the
main channel is provided.
2.
Seaward Approach. The bearing from seaward of
the approaches to the main channel (using the angular unit of measurement designated in line ALPHA) is provided. If this information is already known and has not changed, report NC. If this information does not apply to
this mission, then report NIL. If the team was unable to
determine this information because of the enemy situation or other considerations, they will report NAR (not able to record) and explain the reason in line KILO (remarks) of
this report.
3.
Reference Points. The entrance to the main channel
may be fixed by means of transits and/or bearings of prominent features that can be observed from seaward.

## Reconnaissance Reports Mcrp 2-15.3B Reconnaissance Reports Guide

These features must also be recognizable on a map or
chart (these reference points may be precoordinated and assigned code names or other designations before the team is inserted). This information is reported in the following sequence.
A. Prominent Features. This includes the description and location of the feature followed by its bearing from seaward at the entrance to the main channel. If more than one feature is being used to get a resection for the channel entrance, then the features are
numbered sequentially and described individually.
They are numbered 1, 2, 3, and so on.

- or -
B. Transits. Transits are two points that are recognizable when viewed from seaward and can be located on a map/chart. Transits will line up one behind the other when the boat is on the correct azimuth to the entrance to the main channel. Transits are reported by giving a brief description of each point and its location so that it can be plotted on a map/chart. If more than one set of transits will be used to locate the channel entrance, they will be reported individually and numbered sequentially 1, 2, 3, and so on.

DELTA
Navigation Aids. A local system of buoys (if any) or
markers placed by the teams is reported by using the following code:

## Notes: 1. Characteristics Of Personnel Drop Zones:

A. Surface. A flat, resilient surface without obstructions is technically the most suitable for a troop drop zone.

B. Obstacles. Obstacles preventing the use of a drop zone are built-up areas; high-tension wires; cliffs; ravines; and normally rivers, ponds, and lakes near the intended drop zone. However, jumps on lakes or in any large body of water can be carried out by specially equipped and trained personnel.

C. Other Areas. If considered operationally necessary, drops may be made in wooded or forested areas, mountains, or lakes by using specially equipped and trained personnel.

2.

Special Considerations for a Cargo Drop Zone.

The required characteristics are similar to those for personnel drop zones. In addition, they should be accessible to vehicles or at least crossed by paths to simplify the collection of the equipment and supplies. Dropping supplies over water should be considered only under special circumstances.

3.

Special Drop Methods. Use of methods such as ultra-low-level-approach (ULLA) will require specialist

## Dzrep

representation on the team or at least special training in
the technique to be employed.
KILO
Vehicle Exit Points. This line reports, by grid reference,
possible vehicle exit points from the drop zone to predetermined line(s) of communications.
LIMA
Drop Zone Markings. All drop zone marking/location
aids are to be prebriefed, and only variations from the brief need to be reported. When smoke is being used as a drop zone location aid, the team should indicate when
smoke is being released but not the color. The pilot of the lead aircraft should read back the color seen, and the team should confirm that the correct color has been spotted. A *no drop* signal should also be prebriefed before the
team is inserted.
MIKE
Recommended Direction of Run In/Run Out Tracks.
This line reports recommended tracks for the aircraft run in/run out; these are expressed in the unit of measurement listed in line ALPHA. This information is transmitted in the following sequence:
1st.
Primary run in/primary run out track.
2nd. Alternate run in/alternate run out track.
NOVEMBER
Target Approach Point (TAP). The recommended TAP
should be reported only if one is observed that is

more suitable than that previously selected and briefed. If applicable, report in the following sequence:

1st.
Primary TAP.
2nd. Alternate TAP.

PAPA
Obstacles and Hazards on the Run In/Run Out
Tracks. This line reports major obstacles in the vicinity
of the drop zone and along recommended run in/run out tracks. If unable to recommend run in/run out tracks, all major obstacles and hazards in the area are reported by using the following letter codes and sequence:
Type of Obstacles/Hazards
Letter Code
High-tension wires
A
Built-up areas
B
Cliffs
C

The following is the sequence that will be used to report
this information:
1st.
Bearing from the impact point (IP).
2nd. Type of obstacle (using the letter code).
3rd. Distance from IP.
4th.
Height of obstacle (using unit of measurement
designated in line ALPHA).
Note: If it has not been possible to fully observe the area
between the TAP and the drop zone, the suffix N (not observed) should be added to the end of this line.
QUEBEC
Ground-Air Communications.  This line includes primary and alternate ground-air communications line numbers if they are different from the precoordinated frequencies. The changes will be reported in the following order:
1st.
Primary frequency.
2nd. Alternate frequency. ROMEO
Enemy. Known enemy positions, strengths, and weapons
are to be reported sequentially in the following format:
1st.
Grid reference of the enemy position.
2nd. Strength/number of enemy observed.
3rd. Weapons, especially any weapons systems that
could jeopardize the accomplishment of the airborne operation.
Note: A SPOTREP/SALUTE report should normally be
transmitted to clarify and more accurately describe all enemy sightings and intentions.
SIERRA
Weather. The weather is reported at the time that the reconnaissance is completed and as required and briefed before the team is inserted. This information will be
reported in the following sequence:
1st. Wind direction (from which the wind is blowing)
and estimated speed (using units of measurement designated in line ALPHA of the report).
2nd. Cloud coverthe portion of the sky that is obscured, in eighths, and the estimated base above the drop zone.
3rd. Visibility.
4th.
 Temperature.
TANGO
Remarks.   Other information that is not covered as part
of the report but that could prove vital to the accomplishment of the supported unit's scheme of maneuver is

included. This information should be covered as part of the patrol's IRs.

Notes:
1.

Lines from the report need not be transmitted when the information is either already known or not required. NC (no change) can be used to confirm information already prebriefed in the reconnaissance brief.

2.

The following documents are relevant to determining the precise parameters for size and marking of the zone.

A. Standardization Agreement (STANAG) 3570, Drop Zones and Extraction ZonesCriteria and Marking.

B. The appropriate national standing orders, manuals, or instructions on drop zones.

Note: When the ground is covered with snow, also report the subsurface of the landing site.

3rd.  Ability of the surface of the landing site to recirculate. Whether or not the surface will recirculate is reported by marking Y (yes) or N (no). Recirculation is the effect of the downwash from the helicopter, which is liable to pick up sand, dust, or snow and blow it through the rotors, thereby severely reducing visibility for the pilot. This will
have an effect on the frequency at which the helicopters can safely land and take off.

## Hotel 1. Direction Of Approach 2. Direction Of Egress

Notes:

1.
The approach and egress azimuths are reported in
the unit of measurement designated in line ALPHA. Whenever possible, these directions are into the wind. Oftentimes, the enemy situation, orientation of the long axis of the landing site, and obstacles surrounding the landing site will dictate an alternate direction.
2.
Direction of approach is not necessarily the same
as the direction of landing, which will normally be decided by the pilots.
JULIET
Wind Direction and Speed.  Wind direction is reported as the direction from which the wind is coming; this is the same bearing that a helicopter would use to fly into the wind. These measurements are reported by using the units of measurement designated in line ALPHA.
KILO
Approach Angle.  This is dictated by the height and
proximity of surrounding obstacles. The normal maximum angle should be no steeper than 1:10. Other limits may be prebriefed depending on the squadron's standing operating procedures and other considerations, such as height AMSL and weight restrictions on the helicopters.

LIMA
Locations and Types of Recognition Aids.  The locations and types of landing site recognition aids that are provided for any particular team must be prebriefed
and coordinated with the aviation combat element and the ground combat element before the insertion. The
recognition signals must be assigned letter codes similar to those listed below. These should be changed and updated before each operation as the situation dictates. The information in this line is reported in the following sequence by using letter codes that are coordinated before the operation and insertion.
1st. Grid reference of the recognition aids. 2nd. Type of recognition aid employed of those
precoordinated, for example:

Type of Recognition Aid

 Reconnaissance Reports
QUEBEC
Enemy. Known enemy positions, strength, and weapons are to be reported as a sighting number followed by grid reference, strength, and weapons critical to the accomplishment of the helicopterborne operation.

Note: A SPOTREP/SALUTE report should be transmitted for each enemy sighting to further clarify all enemy sightings and to give higher headquarters a better idea of the enemy's strength and possible intentions.
ROMEO
Position of the ART. This line is transmitted only if
the team is staying in proximity to the landing zone
during the helicopterborne operation. This information is reported to prevent the team from being mistaken for the enemy.
SIERRA
Obstructions. Obstructions in the direction of the helicopter's approach and exit are to be reported by using the following letter code:
Type of Obstruction
Letter Code
Building
A
Trees
B
Poles
C
Pylons and high-tension wires
D

Note: Obstacles will be reported sequentially by using
the following format:
1st. Grid reference of the obstacle.
2nd. Code letter of the obstacle. 3rd. Height of the obstacle (using the unit of measurement designated in line ALPHA).
TANGO
Exits From the Landing Site. This line is used to describe all exit points from the landing site. Exits are reported in the following sequence:
1st. Grid reference of the landing site exit.
2nd. Description of the exit using the following letter code:
Exit Description/Capabilities
Letter Code
Infantry. If the exit is usable by
A
infantry only, report the exit width after the letter code (using the unit of  measurement designated in line ALPHA) and describe the type of exit.
Wheeled Vehicles. If the landing
B
site exit is usable by both infantry and wheeled vehicles, report the exit description by using the letter designator followed by the width of the exit.

VICTOR
Remarks. Other pertinent information, such as a landmark to the landing zone, can be described in this paragraph, along with any other information as designated in the patrol's IRs.
Notes:
1. Any line from the report for which the information is
not known or not required should not be transmitted (to prevent the team from being located). NC (no change)
is transmitted to confirm information given in the reconnaissance briefing.

2. Helicopters can easily be deceived by the enemy unless precoordinated recognition signals are used by the team manning the landing site.


3. When smoke is being used as a location aid for the helicopters, the team should indicate when the smoke is being released but not the color. The pilot of the lead helicopter should verify the color of the smoke seen, and the team will confirm that it is indeed the correct signal. Also, teams should avoid using white phosphorous (WP)/white smoke (HC) in areas where there is much smoke from fires, as this will confuse the pilots and waste valuable time.

4. A wave-off signal should be precoordinated before the team is inserted in case the landing site is compromised immediately before the helicopters land.


5. When the team and the helicopters are transmitting on an uncovered net, the team must be prepared to authenticate when transmitting the zone brief before the helicopters come into the zone.

A. The route is passable to all traffic in any weather, except in deep snow or during flooding.

B. The route normally includes roads with waterproof surfaces only.

## Routerep

2.
Route type Y has the following characteristics:
A. Volume of traffic may be limited by bad weather, for example, muddy verges or shoulders.

B. The route normally includes roads that do not have waterproof surfaces and are considerably affected by rain, frost, thaw, or heat.

C. Roads may have to be closed for short periods.

Heavy unrestricted use during adverse weather may cause a complete breakdown of the route surface.

3.
Route type Z has the following characteristics:
A. Passage is possible only during fair weather.
B. The route quickly becomes impassable in bad weather.

C. The route cannot be kept open by maintenance short of major construction.

DELTA

## Surf Obsevation Report (Surfrep)

Begin the report with the subject line of the message and the serial number, followed by the code name and/or map sheet information as required.

ALPHA
Units of Measurement. See the table on page 3.
BRAVO
Time. This line provides the DTG of when the SUR-
FREP was completed.
CHARLIE
Significant Breaker Height. This includes the average
height (in the unit of measurement designated in line AL-
PHA) of the highest one-third of all breakers observed in a 10-minute period (expressed to the nearest one-half foot or one-tenth meter).
DELTA
Maximum Breaker Height. The largest breaker observed is reported in the unit of measurement designated
in line ALPHA.
ECHO
Period. This line provides the time (in seconds) between
breakers to the nearest one-half second.
FOXTROT
Breaker Types. The number of each type of wave is provided, followed by the letter code of that type of wave, as indicated by using the following letter code:
Type of Wave
Letter Code

Spilling. The wave becomes
A
unstable at the crest and forms white water at the crest. The white water (foam) expands
slowly down the front face of the breaker. Breaker action is mild.
Plunging. The wave crest becomes
B
so much faster than the base of the wave that it falls almost into the trough with violent action. The resulting foam appears almost instantly over the complete front.
At times, air is caught in the breaker as it tumbles forward, creating a type of explosion.
Surging. The wave crest tends to
C
advance faster than the base of the
wave, suggesting the formation of a
plunging breaker. However, just before breaking completely, the wave base advances faster than the crest
and the plunging is arrested with the entire wave breaking on the beach, instead of on itself. These wave types
are generally found on beaches with
a steep gradient.
GOLF
Angle/Direction. This line includes the acute angle (in
degrees) formed between the breaking lines and the shoreline, expressed to the nearest five degrees. The breaker direction is the direction toward which the breakers are moving; it is expressed as R (right) or L (left) of the observer when facing the beach from seaward.
HOTEL
Littoral Drift (Inshore Current). The speed of the
current moving generally parallel and adjacent to the shoreline is expressed in the unit of measurement designated in line ALPHA. This measurement is followed by the direction, R (right) or L (left), of the current as viewed from seaward. This is the direction toward which the current would push a boat traveling toward the beach.
JULIET
Lines of Breakers and Width of the Surf Zone. The
number of well-defined breaker lines in the surf zone is reported, followed by the width of the surf zone, by using the unit of measurement designated in line ALPHA. The width of the surf zone is the distance from the outermost breaker line to the extreme limit of wave action on the beach.
KILO
Remarks. This line includes specific factors that could
affect the above-reported information, for example, strong winds, restricted visibility, or dangerous marine life off the landing beach, and other information as stated in the patrol's IRs.

Notes:

1. Spilling wave action can generally be considered the least violent and dangerous to small boats and landing craft. 2. Surging wave action is generally the most violent and dangerous to small boats and landing craft because of the breaking action directly onto the beach. 3. Plunging wave action falls somewhere in between the two extremes, depending on storm action and other considerations.

## Mcrp 2-15.3B Surfrep 141 Reconnaissance Reports Tunnel Report (Tunnelrep)

Begin the report with the subject line of the message followed by the report number/serial number, code name, and map sheet details as required.

ALPHA
Units of Measurement.  See the table on page 3.
BRAVO
DTG. This line reports the time when reconnaissance
was completed.
CHARLIE
Location and Classification. This line provides the grid
reference of the tunnel location, followed by the engineering classification, if known. If there is not a person in the patrol who is qualified to classify the tunnel or if, because of the enemy situation, the patrol was unable to get the tunnel classification, then the letter code NIL will be reported in its place.
DELTA
Length and Condition of Tunnel. This information is
reported in the units of measurement designated in line ALPHA in the following sequence: the length of the tunnel, followed by the condition of the tunnel. Tunnel damage will be classified by using the following letter code:
Condition of Tunnel
Letter Code
Not Damaged. There are no restrictions
A
to military traffic other than the dimensions of the tunnel.
Boobytrapped, But Not Damaged.
