I think they do. The flare gun DOES alert friendlies about enemies (Without giving away the position of the sniper, as the flare is pretty dim until "detonation". So unless it's a night map, then you'll be safe.), and I'm sure that if a tank shows up, that they're gonna get some type of air support on the horn.
