New Specialty Ambush battle modes:
Infantry battle: Infantry only battle, no vehicles can be called in.

Tank Battle: The entire map is red-zone for infantry and vehicles except tanks. Only infantry area is the initial spawn. Tanks can travel the map normally, but if an infantry hops out, he's instantly in red-zone with a super short timer. The only vehicles that can be called in are tanks.

Dropship Battle: The entire map is red-zone for infantry and vehicles except for Dropships, who can traverse the map normally. The only vehicles that can be called in are dropships.

LAV Battle: The entire map is red-zoned for infantry and vehicles except for LAVs. Only LAVs can be called in.

+1 but only to infantry-only ambush.
Tanks only would be awesome super fun lines of snipers.
Dropships only would be railguns railguns everywhere. Also dropships go down pretty easy.
LAVs only nobody dies ever. Except gunners and that'll be rare one way or the other.

Custom "gladiator" matches where these rules are set or organized beforehand. The ability to set all kinds of restictions or buffs or mods but you don't get money and SP the same as you would in "real" games. Then you guys can peek over hills in your tanks all day. Or do certain weapons only. Shotguns only sounds fun to me I guess.
