Guardian or Team Leader

This is taken from a game and is REALLY simple. I just want to post here to see if I can get feedback on how to tweak the game mode a little to work in airsoft outside of a video game. For any players of Gears Of War 2 or Rainbow Six Vegas 2, you know how this works. Basically two teams of equal numbers start opposite of each other. A team leader is elected from each side. So long as your team leader is alive, your team is allowed to respawn. You're team leader is a single life soldier and upon being hit, the team loses respawns. Your objective is to keep your team leader alive while eliminating the enemy team, requiring you first kill the enemy team leader. In Rainbow Six vegas, they have an added objective. Either kill the entire team or get your team leader to an extraction point. It definately promotes movement against camping. Any ideas or possibilities of bringing this onto the field?
