Yeah, I just meant what branches specifically. Like Navy/Marines or what type of Marines they were, etc. Just curious. The Halo Marines, as I've stated above, are some of my favorite fictional military characters, mainly because Bungie (and now 343) has always been very detailed and true to actual military ranks, names, structure, etc. They base their ranks, names, terms etc. off of the actual US Marine Corps. So as someone who has an interest in the military and military friends, these details are fun for me.
