The Revive

This must be your first BF game?  Everyone in your squad can revive you.  Only 2 of the specialist can revive everybody.  So if the other players that aren't in your squad are not those 2 specialists then they cant revive you.  That and it has always been like that in BF games.  Rarely will you find a medic that will revive in any BF game.  I on the other hand give out ammo and revives like a stranger giving kids candy!
