I thought this was a thread about videogame teams, (In which case I can cover Sniper or Ninja)
Well, in games, it depends. If it is capture the flag, a favourite around my part of the world, I'm the sneak. Whether its defensive, and the enemy thinks they are all alone to find I am above/behind/DIRECTLY IN FRONT/to the side of them. Or offensive, where they have 20 man patrols around the intelligence flag and suddenly... What?! Where did it go!?!
