Operation: TREBUCHET was the last major UNSC offensive against the human insurrection before first contact with the Covenant empire. Our mod will focus on the struggles of the common soldier, rather than the elite spartan warriors, during that offensive. Experience the Halo universe from a new, brutal perspective. For the most up-to-date info regarding the mod and the community, monitor the official subreddit, r/OperationTrebuchet.

Um.Marines? By lore they are Army Troopers bro. Please change that. Pretty please. Lol. Marines HCW is fine but the whole Army Troopers being Marines is wrong. Could we get a group unit of HCW Marines too please? Thanks Bro. Great work.

De heck you talking about? In Halo almost all ground infantry are Marines? They do have UNSC Army and Airforce units but they are usually regulated to asset protection and garrisoning duties on individual planets.
If it is a unit that moves from planet to planet then it is almost definitely a Marine unit. Operation Trebuchet specifically mainly used Marine forces cooperation with Navy.

What do you mean by "canon" style marines? Nowhere, as far as I know, has it ever been stated that the marines wearing the M52B armour as seen in Halo 3 are universally what Marines canonically look like.

Is it really so hard to believe that a military organisation as vast as the UNSC Marine Corps could have a variety of BDU variants depending on operational necessity, inter-branch coordination, and even just differences based on unit tradition and de-centralisation of logistics? All designs of marine should be taken as canon.

As Max said

The specific variety of H3 marines will be for URBAN. That is what you are looking for.
I like the look of the H2 / H3 marines.

This version isn't updated to the most recent one. The steam workshop mod is, I think, the most supported.
