Well.. we kinda' already had one, from the first page of this discussion.
I'm not sure about naming them regiments though...
According to Dictionary.com:
Regiment
Military. a unit of ground forces, consisting of two or more battalions or battle groups, a headquarters unit, and certain supporting units.
Battalions -
Military. a ground force unit composed of a headquarters and two or more companies or similar units.
Company -
Military. a. the smallest body of troops, consisting of a headquarters and two or three platoons.
Platoon - military unit consisting of two or more squads or sections and a headquarters.
If anything, the Website becomes the Regiment, and then the States become Battalions, but the companies would fall under that somehow, and then platoons? squads?
I'd rather do it like the 501st does, with a Spartan Legion and State Garrisons/Outposts and Garrison Squads. It just seems more appropriate to me?
