What makes TTR TTR?

[MaSwIcK]

calling in for airsupport ?
Like the thing they have in RO and Vietcong =) You call in this airsupport, and after a lil while these planes come and fire towards the ground and drop bombs.
AND, on certain object/defend map, or like on a assault/defend map, there could be this big door or this bridge you must call in support for.. And you must go to this place up high to get contact =) Risky job, but somebody has to do it =P
