HECU

The Hazardous Environment Combat Unit, or HECU hyphenated is an elite marine unit in the US Marine Corps, tasked with containing hazardous materials and events. The unit is dispatched during the Black Mesa Incident, tasked with not only killing aliens, but killing the innocent BM Staff & BM Security. However, during the deploying of Black Ops, and as Xen creatures get tougher and tougher, HECU soldiers may team up with the staff and security of Black Mesa, in order to survive, and most importantly, escape.

Main Info
The HECU Marines are sent in to clean up the Black Mesa Research Facility following the incident, their mission being to eliminate anyone with knowledge of the research project and the extraterrestrial life involved. They are specially trained at the Santego Military Base to deal with a variety of indoor combat situations, particularly those involving dangerous environments and unconventional hostiles. Apart from combat roles, they make take on specialized capacities such as becoming Medics or Engineers. They are initially described as working in cooperation with the Black Mesa Security Force in case of emergency circumstances, a role that changes during the progression of their mission.

Roles
When it comes to making a team, combat specialists and support specialists are useful in the field. When it comes to securing areas and training soldiers, bootcamp specialists are recommended for you.

Average Soldiers
These soldiers are generic marines, usually being grunts carring rifles such as M16s, M4A1s, MP5s, and M16A2s with M203s. These soldiers are the base of a team.

Combat Specialists
These are specialists that mostly use different weaponry than average soldiers, these being:

Shotgunner
The Shotgunners are troops with shotguns as their main gun (M1014 or SPAS-12), they usually flank their enemies and surprise them from behind, very dangerous in urban combat. Most Shotgunners use PCVs.

They may flank you while the other units supress you. Take advantage of them in long ranges because their shotgun is buckshot and there would be no accuracy, most rounds would disperse and you can end up losing ammo if you keep trying and their pistol loses effectiveness on long ranges.

Machine Gunner
The Machine Gunners are by far dangerous on both long and short ranges due to their main gun being a LMG (M240 / M249, M249 recommended mostly due to M240 being heavier than the 249's). Most Machine Gunners use PCVs.

They usually suppress the enemy and support the other units in combat so that another member goes to the enemy's position and attack them on surprise, It's recommended to try and flank them instead of directly going in combat with them.

Snipers / Ghillie Suit Soldier
Ghillie Suits, or snipers are units that are mostly hidden on mountains or straight up on foot. Still, they can be very dangerous. These soldiers don't have PCVs

Mostly seen using M40A1's, ghillie suit soldiers can also have ARs or SMGs when on foot. If there's a big wave of enemies, it's recommended to stay low when in foot, while in mountains its recommended to take em out 1 by 1 or stay low also.

Ghillie Suit Soldiers can also come in with forest ghillie suits that can possibly make an cactus-like camoflauge. Not recommended in mountains.

Squad Leaders
Squad Leaders are leaders that gives orders to soldiers. (WIP)

Support Specialists
Sure, combat specialists are needed when alone in combat, but there's also soldiers who will help you when you're injured or when your stuck. These are specialist who

Medic
The medic is a important specialist, this specialist can bring bigger I.F.A.K's, medkits and injectors to the field and can heal any injured men.

Mostly needed whenever a man is downed / severly injured. Medics can treat wounds fast due to them being trained for these types of situation. These specialists are mostly seen with a 357. feeded Desert Eagle. This specialist must be protected at all cost due to just having a pistol (May grab different weaponry as the time passes),

Engineer
The engineer is a important specialist, he's prepared with a blow torch for any locked door found on Sector L / J, Engineers can also set down turrets in replace of the blow torch w/ gas tank.

Same with the medic, this specialist must be protected at all cost due to just having a pistol. The engineer cannot open any blocked doors, anti-blast doors or thick doors.

Bootcamp Specialists
Bootcamp specialists are soldiers that guard the Santego Military Base and make trainings to recruits. MPs and Drill Instructors can also be seen on BMI's Bootcamp.

Military Police
The Military Police, or MP consists of members of the United States Armed Forces that uphold the law among their fellow soldiers. They assist the Hazardous Environment Combat Unit in their duties, they werent send during the Black Mesa Incident. Premium benefits only.

Drill Instructors
Drill Instructors are marines that make trainings to teach recruits. They are usually the most cruel people you'll meet as a HECU marine. There is atleast 2 drill instructors in each training.

Miscellanea
Misc specialists are not really needed in field. They're just there to help wounded man and attend trainings.

Stretcher
The stretcher (for his namesake) is a specialist that morphs you into a medic and another medic holding a stretcher. Not really needed in field, just to transport downed men.

Recruits
Recruits are not specialists, they're just there to attend PCV training, if they make it they'll obtain a PCV. If not, they'll get a regular combat vest.

Technology
The HECU engineering and technology is variable, from blow torches to powered combat vests. Here's a small list of the HECU technology.

Blow Torch
The blow torch is a small object that allows you to break any door by breaking its weld, used by HECU Engineers. The Blow Torch can be buyed as a handheld item. This can also light up cigarretes (Seen in OP4), but its not recommended at all.

Gas Canister
The gas canister is used by HECU engineers on their back, aside of the small backpack they wear. This is necessarily needed when going in as a HECU engineer with a blow torch.

Turrets
A Turret or Sentry Gun is a AI controlled object that can be placed anywhere, will come out of its 'sleeping process' when anyone steps close to the turret or walks into a red turret beam, deployed by HECU Engineers. A turret gamepass can be buyed, morphing you into a HECU turret.

I.F.A.K
The I.F.A.K (Invididual First Aid Kit / Improvised First Aid Kit) is a vest pouch used by every troop in case they get injured. HECU medics carry bigger IFAKs to combat.

Powered Combat Vest
The PCV is a combat vest powered by power. It can protect you from bullet shots, hazardous chemicals and etc at cost of its power. The PCV also has pouches for magazines, grenades and misc. A sling can be placed on the PCV, allowing to place LMG ammo and 12 Gauge buckshot rounds.

PCV Helmet & Gasmask
"In addition to providing protection, your PCV has other capabilities. Once the light goes out, the door in front of you will open. Activate your night vision goggles to navigate this maze and exit on the other side. Now move like you've got a purpose!"

The PCV comes with a helmet & gasmask. The helmet is an average helmet with urban / forest camo on it, meanwhile the gasmask is a electronic device that connects to the PCV, the gasmask haves a HUD (Heads-Up Display) that monitors the state of the user and PCV, how many ammo does the current weapon on hand haves, the weaponry you have and the wounds & waste the user has been suffering. The gasmask also contains built-in night vision goggles.

PCV Gloves
Possibly, possibly the PCV haves also gloves that monitor how many ammo is there on the mag. The technology possibly seems to have a camera that analyze via heat vision how many bullets there are on the mag, the process is way too fast. Either this, or the helmet also haves a hidden camera that sees through heat vision the weapon's mag, bla bla bla.

Tripmines
Tripmines are green objects that resemble binoculars. They can be placed on walls and emit a cyan laser. When something is detected by the laser, the tripmine explodes. It can be disabled or blown up prematurely by shooting at. Perfect for taking out multiple targets.

Satchel Charge
A satchel charge is an green pouch with explosives on it, resembling C4s. The satchel charge also has a detonator to detonate the explosive. Perfect for taking out multiple targets. Just like the tripmine, it can be disabled or blown up by shooting at it.

Trivia

 * The H.E.C.U is famous among the 2 Gear / HLRP community.
 * Most of the HECU marines (BMI) are fail roleplayers, this due to not reacting to other players, not understanding the game lore or simply just retarded.
 * This is the most used team in BMI.
 * The MK2 Grenade, which is used by HECU, is a grenade used back in WW2, and later replaced with the M67 grenade. Black Mesa can take place from 2000 to 2009.
