In Half-Life and Black Mesa, the HECU are never referred to as Marines specifically. They were always called "The Military." In fact, Black Mesa adds more confusion with lines referencing the Army, lines referencing the Marines, and textures with USMC on them. However, the grunts look like their in the Army, and they have an apache helicopter! So I always figured the HECU in Half-Life were a PMC, while in Black Mesa it was a joint operation. However, rather than giving them urban camo for some reason, I decided they both should get their own uniforms.

I hexed a set of models to use my Multicam textures, while the original models are using M3Luckycharm's Marpat textures. If you don't like either when it is released, you can still use these hexed models for "damaged body types" or something. I also had to change some variables in the code, but nothing major. It's just a small script edit actually.

The grunts randomly select the texture for the most part, but certain individuals the Black Mesa team coded to use a specific setup each time. So the cutscene grunts and the RPG grunt will always use the model type defined by the code, and I can't really do anything about that. Well, I maybe could, but it isn't that big of a deal right now. With that established, sometimes I end up running into a primarily-to-all Army group, and sometimes it's primarily-to-all Marine group. I still haven't set up the "Army" grunts to gib yet, so it's still very WIP. Additionally, both grunts use the same helmets, gasmask, beret, and gloves. But that is easily fixable by just changing the textures inside either the Marine Folder or the "Barine" folder. Why Barine? Because I wanted to hexing process to go as smoothly as possible.

Right now, I'd say the hack is about... 80%? I don't know how much work that gib system will be, or whether or not I'll make the system even more random.

EDIT: Both groups now gib! When you blow up a "Barine" you'll see "Barine" gibs, and when you blow a vanilla Marine vanilla Marine gibs will show. Additionally, I changed the facial system a bit. There will be a new set of faces on both sets of hgrunts, and standard hgrunts don't all wear gasmasks anymore. It is more like it was in Black Mesa's beta, where hgrunts will have different body groups. Standard hgrunts now also have the ability to smoke cigars, but won't if they wear a gasmask.
