Section II. EQUIPMENT DESCRIPTION

1-5. EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES.

The Aircrew Survival Armor Recovery Vest, Insert, and Packets (SARVIP) is a three part system: survival vest,

armor insert with carrier, and survival, signal and communication components.

Vest. The vest Is fabricated from raschel knit and fire resistant aramid oxford fabrics. It contains a total of twelve

pockets; ten outer and two inner. Together these pockets house all survival, signal and communication components. For

rescue-lift, a nylon webbing harness system is permanently attached to the vest in a cradle fashion and contains both leg

and chest straps. The chest strap also provides the means for attaching the LPU/10 life preservers. The vest also

provides means for attaching a motor housing and face mask carrier when wearing MOPP clothing.

Insert. The armor insert consists of a laminated ceramic/fiberglass composite backed with a 3/4 inch thick foam

padding. The foam padding provides blunt trauma protection when

1-2
TM 1-1680-359-10

1-5. EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES (Cont)

struck with small arms fire. A fire resistant aramid oxford fabric carrier with seven layers of Kevlar (R) is provided to

carry the insert. The Kevlar (R) provides the necessary spall protection from the insert when the insert is impacted with a

round. A cradle type harness arrangement on the carrier is used for holding the insert on the body. A quick release strap

located on the bottom of the carrier allows the insert to be jettisoned during emergencies.

Survival Signal and Communication Components. Placed in the various pockets on the vest are the following

items: compass, mirror, smoke and Illumination flares, sea dye marker, distress light marker, chemical agent detectors,

distress signal kit, operators manual, and survival packets consisting of medical and basic components necessary for

survival.

A pocket is also provided on the vest for carrying a PRC-90 or PRC-112 radio. Operation of the AN/PRC-90 or

AN/PRC-112 will span a wide range of weather extremes. Although the radio circuits are operable over a temperature

range of -30° to +500C (-22° to +1220F), the battery power supply is only effectively operable over a 0° to +54°C (+32°

to +1290F) temperature range. Operating at low temperature reduces battery life. The radio may be stored over a

temperature range of -60° to +60°C (-76° to +1400F).

Section III. OPERATION UNDER USUAL CONDITIONS

2-4. GENERAL. This section provides instructions for wear and use of the SARVIP under normal operating conditions.

2-5. ASSEMBLY AND PREPARATION FOR USE

a. Fitting Armor. To ensure the proper armor insert is selected, individuals must do the following.

(1) Sit erect as shown; adjust feet to ensure that upper thighs are on a horizontal plane.

(2) With upper arms hangingrelaxed, extend forearms and hands forward horizontally.

(3) Place a 4-inch block of wood across your lap so that it is close to the body and in a horizontal position.

2-19
TM 1-1680-359-10

2-5. ASSEMBLY AND PREPARATION FOR USE (Cont)

(4) Select an armor insert that, when placed vertical on the block of wood, the top of the insert is

approximately 1 inch below the suprasternale location. (The suprasternale is the small indenture above

the sternum.) An insert which comes closest to 1 inch below the suprasternale location is your correct

insert size.

b. Fitting Vest.

(1) Put on required flight, MOPP and/or cold weather garments.

(2) Select a vest based on your measurements (refer to paragraph 1-8 for vest sizes available).

c. Attaching LPU-1O/P Life Preservers. The illustration below shows proper placement of LPU.

2-20
TM 1-1680-359-10

2-5. ASSEMBLY AND PREPARATION FOR USE (Cont)

(1) Open vest and lay flat (outside exposed).

(2) Extract chest strap from right pocket tunnel and three retaining loops on rear of vest.

(3) Insert strap through retaining loops of LPU-10/P (ensure LPU-10/P is face up with inflation lanyard facing

down) and through three retaining loops on rear of vest.

(4) Insert strap through retaining loops of second LPU-10/P (ensure LPLI-10/P is face up with inflation lanyard

facing down) and through pocket tunnel on right side of vest.

d. Putting On Armor. For maximum comfort and protection, the body armor must be properly adjusted. The insert

must be worn straight and centered on the front of the chest. Twisted or off center armor affects body balance

and interferes with activities. For proper balance, the shoulder straps must be adjusted evenly. Armor should be

snug but not too tight, as overtightening may inhibit the armor insert quick-release capability.

2-21
TM 1-1680-359-10

The Metric System and Equivalents

Linear Measure Liquid Measure

1 centiliter = 10 milliters = .34 fl. ounce

1 centimeter = 10 millimeters = .39 inch 1 deciliter = 10 centiliters = 3.38 fl. ounces

1 decimeter = 10 centimeters = 3.94 inches 1 liter = 10 deciliters = 33.81 fl. ounces

1 meter = 10 decimeters = 39.37 inches 1 dekaliter = 10 liters = 2.64 gallons

1 dekameter = 10 meters = 32.8 feet 1 hectoliter = 10 dekaliters = 26.42 gallons

1 hectometer = 10 dekameters = 328.08 feet 1 kiloliter = 10 hectoliters = 264.18 gallons

1 kilometer = 10 hectometers = 3,280.8 feet

Square Measure

Weights

1 sq. centimeter = 100 sq. millimeters = .155 sq. inch

1 centigram = 10 milligrams = .15 grain 1 sq. decimeter = 100 sq. centimeters = 15.5 sq. inches

1 decigram = 10 centigrams = 1.54 grains 1 sq. meter (centare) = 100 sq. decimeters = 10.76 sq. feet

1 gram = 10 decigram = .035 ounce 1 sq. dekameter (are) = 100 sq. meters = 1,076.4 sq. feet

1 decagram = 10 grams = .35 ounce 1 sq. hectometer (hectare) = 100 sq. dekameters = 2.47 acres

1 hectogram = 10 decagrams = 3.52 ounces 1 sq. kilometer = 100 sq. hectometers = .386 sq. mile

1 kilogram = 10 hectograms = 2.2 pounds

1 quintal = 100 kilograms = 220.46 pounds Cubic Measure

1 metric ton = 10 quintals = 1.1 short tons

1 cu. centimeter = 1000 cu. millimeters = .06 cu. inch

1 cu. decimeter = 1000 cu. centimeters = 61.02 cu. inches

1 cu. meter = 1000 cu. decimeters = 35.31 cu. feet
