Aside from the fact that most HECU Marines died in the Black Mesa incident (in combat with Xen creatures/ Freeman / after the nuke went off etc.), HECU is a military unit of the United States. In HL2, the world has already been destroyed by the Combine. There's no US anymore, let alone any organized army.

Jan 26, 2024 · Had the HECU and Black Ops not invaded, slaughtering countless Black Mesa personnel and eventually destroying the entire facility, then it's entirely possible (if not necessarily likely) that the surviving scientists of Black Mesa, with the Nihilanth defeated and the worst of the Resonance Cascade over, would be able to end/prevent the Portal ...

Mar 26, 2023 · The HECU have gas masks though which fits the hazardous environment, but the power armor they have in Opposing Force probably didn't exist. I like to think a lot of their equipment is whatever they had in stock from Black Mesa or laying in boot camp, which likely isn't that up to date when you're dealing with mass logistics like this operation.

Feb 12, 2023 · There's no indication that the soldiers Freeman fights on day 1 are HECU, and there are definitely non-HECU forces present at Black Mesa, such as the US Army Apache helicopters. We also never find out what Shepard's team's orders are, so it's not necessarily confirmed that all troops on site had the order to kill scientists on sight.

The HECU are ordered to contain the situation at Black Mesa by killing scientists, security guards and any other personnel. Military personnel are trained to follow orders without question and hesitation, and it takes a lot to make them question an order, especially with a modern, Western professional all-volunteer force like the US Army and ...

Apr 23, 2023 · The HECU do use a mounted M203 during the "On a Rail" chapter of HL1, but that is an only time event. The HECU also use the tripwire mines a lot more often, but the Combine only use the tripwires in Nova Prospekt during HL2, …

Nov 28, 2021 · Unlike HL1 common HECU grunts with white helmet and gas mask, there's just grunts with green helmet anyways in HLOP4. There is some cut sequence that shows common LD HECU grunts jumping off a green truck with white helmet, directly at the same spot in the robot operation sequence in HLOP4.

HECU may be 'busy' with evacuating with other civilians; or Gordon is instructed by the other scientists to fetch Y or do X - seeing how he has an HEV and 'some' guns. Thus delaying him from joining the group out. Gordon may encounter the odd-end HECU that is cut-off, fighting aliens or open to offering some supplies here and there.

The HECU absolutely lost at Black Mesa. Keep in mind that the HECU is a specialized set of marines - thus their numbers are fairly limited. The aliens likely have WAY more numbers, and have even better technology in some cases. This alone probably means the HECU is going to lose over time simply via attrition and wounds.

Jul 5, 2019 · With HECU'S help Freeman is sent deeper into facility where they try to stop the Xen. HECU lose contact with him and eventually we hear " FORGET ABOUT FREEMAN" because HECU think Freeman is dead. Adrian Shepard escorts Dr.Kliener to a hecu osprey extraction where black ops take control. Hear Barney rescued a lost hecu on a radio.
