seems awfully small for a 3v3
anyway, with 3 people on each side i think you need to put in more cover on the outskirts of the town area. the way it looks to me those areas can be locked down with 1 HMG, 1 PAK and a Mortar.
it also seems like that if you place say, an 88, on the outskirts of town it may be able to shoot into the spawn area, not a good thing.
also, with only the small openings in the houses its very easy to lock it down with tank traps and wire and if attacker doesnt have panther/tiger/pershing or bulldozer shermans they are fucked.
