I believe a battalion needs "deployed" members in order to form. Anyone can join a battalion, but to form one you need 5 members with completed suits that have submitted for deployment.
You might be getting ahead of yourself [USER=31442]Brazen[/USER] . You should focus on finishing your suit, then start attending local conventions to inspire others to make Halo suits. Good luck and happy building.
