The Ultra-Heavy Engagement Chassis fulfills a niche role in 
PHYSICS Division operations: namely, engaging massive or heavily 
armed Threat Entities. In the past, encounters with such entities 
could be resolved only by evacuating the area and escalating to 
Response Level 5. Furthermore, in encounters against enemies 
armed with heavy weaponry or armor, Strike Operatives tended to 
fall short due to a lack of armored cavalry support. In light of this, a 
new system was developed to provide both the ability to engage 
massive KTEs, as well as provide rapid and mobile heavy armor 
support. 


Mk. | and Il U-HECs suffered from multiple drawbacks in their 
design: for instance, the ground pressure caused by a bipedal 
machine the size of a tank caused severe damage to paved roads, 
as well as resulting in the machine and operator bogging down or 


collapsing urban structures. Further problems included operator 
exhaustion, overheating, and balance issues. As time went on, 
however, advancements in the fields of nanotechnology and 
Tangential Technology allowed U-HECs to be built lighter, faster, 
and much more responsive. The modern U-HEC (the Mark III 
"Orange Suit") is a much more mobile and agile unit, although still 
requiring infantry support from Strike assets. 


Overview 


U-HECs are designed for situations in which a Threat Entity 
possesses extreme destructive potential, such as a large cryptid, 
Tier 5 or higher energy manipulators, or persons with access to 
heavy weaponry. As stealth is practically impossible due to the size 
of the unit and the noise caused by its operation, U-HECs are 
equipped with "Banshee" audio-visual cognitohazard generators to 
induce panic in non-inoculated personnel. Believing that the system 
is more effective if it has the full attention of the target, some U-HEC 
operators use bright colors or gaudy ornamentation to draw the 
attention of the enemy. 


The exact construction and composition of the Mark II] U-HEC is 
classified, but are known to include: 


¢ Buckypaper bilayered with dilatant gelatin in order to absorb 
shock from bullets and explosives. 

Silicon nanofluid cooling system integrated into a bodysuit 
similar to that worn with the White Suit. 

« Pseudomyomer exomusculature similar to that used in the 
White Suit, but augmented with miniaturized high-torque 
electromechanical servos for greater strength at the cost of 
some response time. 

Ceramic plating to reduce electrical conductivity. 

Vaporizing liquid extinguisher for protection against flammable 
agents. 

¢ Ultra-high-molecular-weight polyethylene (UHMWPE) outer 
shell. 

Full environmental hazard protection, including toxin filters 
and rebreathers. 

* OCULUS sensor suite, including VERITAS imaging system. 


¢ Ram-Air Parachute system for aerial deployment. 

¢ "Firestorm" Antipersonnel Directional Explosive (ADE): scaled 
up version of the "Roomsweeper" hemispherical claymore 
mounted on the White Suit. This system was added to early 
U-HECs after an incident in which a U-HEC operator, cut off 
from infantry support, was overwhelmed and killed by multiple 
enemy infantry who climbed onto the suit and prised the 
operator out of the pilot compartment. The system consists of 
a series of directional mines mounted on the exterior of the 
unit which can be set to detonate at the command of the 
operator. 


I've operated with U-HECs six times, and each time, it's 
been fucking intense. Even if you're inoculated against 
the cognitos, it's fucking terrifying to see that huge thing 
smashing through small buildings and shrugging off 
small arms fire like rain. | can't imagine what it must be 
like for anyone who has to go up against that thing with 
the full force of the Banshee shrieking at them: shitting 
their pants and running screaming for the hills is the 
kindest thing I've seen happen. 


The downside is, it's easy to feel invincible with a giant 
fucking golem smashing everything in your wake, but 
that's when things get the most dangerous. Not everyone 
turns and runs. Some people respond to abject terror by 
going violently berserk. Plus, even when you're wearing 
a tank, there's plenty of things out there that kill tanks 
just fine. Some of them are out of Banshee range, too. 
So if you ever have the honor and privilege to wear an 
Orange Suit, remember: you're not invincible, even if 
everyone else acts like you are. And that thing you're 
wearing makes you the biggest target on the battlefield.

SCP-648: The Labyrinth 


Item #: SCP-648 
Object Class: Euclid 


Special Containment Procedures: As SCP-648 cannot be moved, 
it is contained on-site under the cover of a secondary entrance that 
is closed indefinitely for maintenance. At least two (2) armed, 
undercover guards disguised as site workers must be on duty at all 
times, and any individuals attempting to gain access to SCP-648 
must be detained for questioning. 


Exploration or experimentation within SCP-648 may only be 
performed with prior permission from at least one (1) level 4 
personnel. 


Description: SCP-648 is a hidden entrance of the hedge 
maze near [DATA EXPUNGED]. Although no official record of this 
entrance exists, evidence suggests that SCP-648 was incorporated 
into the hedge maze shortly after its construction. 


When subjects enter the maze via SCP-648, they are displaced to 
what appears to be an extradimensional space separate from the 
real maze. So far, several anomalous properties have been 
observed: 


* The maze behind SCP-648 blocks all radio transmissions, 
preventing communication or remote recordings of the inside 
of the maze. 

* The maze behind SCP-648 has a size inconsistent with the 

hedge maze. Manned exploration attempts have 
explored over 14 square kilometers of maze without reaching 
any exit or edge to the maze. 

¢ The topography and layout of the alternate maze occasionally 
shifts, with the time between each shift completely 
unpredictable. The lower time limit of these shifts is 


Pressure Environment Suit 
(Blue Suit) 


GEN+1 


History 


Early GOC underwater operations utilized SCUBA gear and wetsuits 
no different than those used by military or civilian divers. The limits 
of this system soon became apparent: lack of protection from water- 
borne threats made it completely unsuitable for GOC mission 
objectives. As time has passed, SALPES has evolved as well: the 
modern variation is a far cry from the crude systems used in the post 
World War II era. 


Overview 


SALPES is utilized for underwater operations (both termination of 
KTEs and investigation of PTEs) when a full Atmospheric Diving 
Apparatus (hardsuit) is unavailable or inappropriate. The most 
recent version of SALPES includes: 


¢ Water electrolyzer for production of hydrogen and oxygen 
while underwater. 

¢ Hydrogen powered fuel cell for the SALPES electronic 

systems. 

Form-fitting buckypaper garment bilayered with dilatant gelatin 

to provide ballistics protection, with Nichrome heating 

element. 

¢ Water-resistant "Trident" model OCULUS vision-enhancement 
equipment. 

¢ Rebreather system/SCUBA gear, depending on mission 
parameters. 


Mark IV Vital Energy Radiation 


Imaging Tactical Awareness 
System ("VERITAS") 


TanGenT 


Note: Because of the sensitive nature of this technology, all 
information regarding the true nature of Etheric Resonance Imagery 
(ERI) is classified Level Q by order of GOC High Command. This 
document will cover only the operation of the VERITAS device by 
GOC Field Operatives. The device itself is classified as "Black Box" 
technology and should not be repaired by anyone other than an 
authorized Coalition technician. ERI technology is to be considered 
Tangential Technology, and must be outfitted with a self-destruct 
device to prevent downstream technology from being released to the 
civilian population. 


Overview 


The VERITAS Resonance Imager is a fourth-generation device 
based on the principles of Etheric Resonance Imagery originally 
discovered by Semyon Kirlian in 1939. This is not to be confused 
with what is commonly known as "Kirlian Photography," which is a 
simple corona discharge phenomenon. Prior versions of the system 
(including COLLICULUS), required a separate Resonance Imager 
and Viewer, making the system too bulky to be carried by a single 
person. Recent miniaturization advances have allowed the entire 
system to be incorporated into a single headpiece, most commonly 
combined with low-light, infrared, and ultraviolet imaging technology 
in the OCULUS vision enhancing headset. 


Like all ERI devices, VERITAS functions by detecting the distinctive 
Aetheric Energy Fields (AEF), or Elan Vital Energy (EVE) given off 
by living creatures during the course of normal life functions. By 
measuring the wavelengths and intensity of these energy fields, 
information regarding the nature of the life form, its mental and 
physical state, and any paranormal alterations can be determined. 


In its simplest configuration, a single VERITAS unit can be used to 


detect the presence of higher life forms, even through a wall or other 
vision-obstructing obstacle. However, the device's true potential is 
only reached when two or more units function in tandem. By 
triangulating the position and nature of various AEFs, a three- 
dimensional map of the area (including the locations of all hostiles) 
can be provided to a mission commander or overwatch.

Excerpts from PHYSICS Division Field Manual 13: 
Special Circumstances, Humanoid Threat Entities 


Introduction 


Reality Benders (Type Greens) have a certain mystique among 
GOC operatives. Some operatives even argue that it is impossible to 
terminate a Type Green, and it is suicide to even try. The kill record 
of our organization says otherwise. The key to terminating Type 
Green entities lie in finding and taking advantage of their few 
weaknesses. In 95% of cases: 


¢ Greens cannot predict the future and can be taken by 
surprise. 

* Greens have limited range and cannot affect what they cannot 
perceive. 

* Greens cannot impose their will on anything if they have no 
will to impose. 

¢ Greens have human foibles and can be manipulated 
emotionally and/or rationally. 


Sequence 


99% of Type Greens undergo the following sequence of 
psychological changes as their powers progress. 


PHASE 1: Denial: The subject refuses to acknowledge their ability to 
warp reality. The Type Green will attempt to rationalize away their 
abilities by various means. In some cases, the Type Green will end 
here: their ability will be self-suppressed, and they will not proceed. 
However, most then proceed to: 


PHASE 2: Experimentation: The subject acknowledges their abilities 
and begins to test the limits of their powers. In general, Type Greens 


tend to experiment in one of two patterns: slowly, methodically, and 
carefully, advancing a small amount at a time, or in a small number 
of sudden jumps. In any case, the subject will generally remain in 
this mode for some time, before proceeding to: 


PHASE 3: Stability: The subject reaches the limit of their powers, 
and determines the boundaries of their abilities. The Type Green 
achieves control over their reality shifts, and can manipulate them as 
necessary. More importantly, they can choose not to utilize their 
abilities, if needed. 


Phase 3 is usually characterized by attempts to live a "normal" life. 
The subject will continue in normal routines, and aside from 
necessary precautions to prevent losing control, will utilize their 
abilities only in private, and only in a manner that will not harm 
others. These Type Greens may be classified as Threat Level 1 
(monitor, do not engage), but should be monitored closely, due to 
the risk of proceeding to Phase 4. 


PHASE 4: The Child-God: Sadly, the majority of Type Greens will 
eventually progress to Phase 4. During this phase, the reality bender 
becomes obsessed with the power it possesses and will attempt to 
utilize it for personal gain at the cost of others. This phase is marked 
by reduced empathy for other humans, inability to accept personal 
faults, and increased megalomania. 


Although warning signs are numerous, the key aspect of a Phase 4 
is the use of their abilities to manipulate other humans. Teenage and 
young adult Type Greens will typically use their abilities for sexual 
purposes, while children will attempt to make strangers their 
"friends." Older adults may attempt to manipulate others for love or 
financial gain. Although a few cases have resulted where the Type 
Green then reverts to Phase 3, 99% of them will remain at Phase 4 
until eliminated. For this reason, Phase 4 Type Greens should be 
considered Threat Level 5 (Immediate Threat) and eliminated 
immediately, as they represent a major threat to all aspects of the 
Fivefold Mission. 


Termination 


Any attempt to eliminate a Type Green must take into consideration 
the three factors for Dynamic Entry in close quarter battle. 


Speed: Type Greens are able to quickly react to any threat. In order 
to ensure a successful kill, the operation must take no longer than 
one second from initiation of hostilities to termination of subject. This 
is the average time it takes for a human being to reflexively react to 
an unexpected threat or event. 


Surprise: Type Greens are able to quickly adapt to known threats. It 
is recommended that a bluff play be carried out: an overt threat is to 
be presented to the subject for them to fixate upon, while the actual 
kill is carried out from an unexpected direction. 


Violence of Action: The kill method chosen to eliminate a Type 
Green must ensure a successful termination on the first shot. Sniper 
weapons should utilize large caliber rounds, preferably hollow-point 
for maximum expansion, or armor-piercing, as needed. Firearms 
are, of course, a secondary kill choice: explosives are 
recommended, but may not be usable due to collateral damage 
risks. If firearms must be used, multiple shooters should be present, 
and all should aim for head shots, if possible, or center torso shots if 
necessary. 


Example 


(Names have been redacted for security purposes) 


Subject Alpha ("Alice") was a 90 year-old Caucasian woman living 
on a farm house in Town A ("Anytown, USA"). Alice first came to the 
attention of the GOC following reports of "ghosts" haunting the fields 
outside her town. Initial covert investigation was able to rule out the 
presence of actual spectral entities through VERITAS scanning. 
Further investigation was approved. A GOC Special Observer 
("Oscar") proceeded to Anytown with a full support team, posing as 
the cast and crew of the reality television program "Ghost Finders 
Inc." 


Subject Alice was discovered to be living alone with two cats. She 
had been widowed three years prior, and her children all lived out of 


state. Subject Alice proved personable and charming, and often 
engaged the operatives in conversation and provided them with tea 
and home-baked cookies. 


Oscar soon determined over the course of the next few days that 
Alice was the proximal cause of the apparitions, as they only 
appeared when Alice was either asleep, or not present. Upon 
engaging her in further conversation, he discovered that she was a 
lapsed Catholic, now agnostic, who expressed a desire to believe in 
an afterlife but was not satisfied by her faith. Agent Oscar theorized 
that Alice was a subconscious Type Green who was expressing her 
grief over her husband's death by manifesting apparitions of his 
ghost.
