Elimination
Usualy at BG when your shot, give your armband to a marshall or it'll be taken by one, then you either find a medic to get a new one, if there going to be running those this year (god i hope not) or exit the game field, take a break, pod up, air up then head back in through an entry point, grab a fresh armband and repeat. Rules will properly be on the BG site or fully explained in the rule book which is sent prior to the game to all the people who booked.
