Having played this against LDDK tonight and been absolutely hammered in the spawn area by a Bradley charge, I would reccommend that the bradley be somehow limited to the town/its outskirts.
Options could be:
Lack of fuel
Mine fields?
tether range (go too far and you automatically lose - would need to be metioned multiple times in the briefing!)
Anything to prevent being shot to bits while we're still mounting up in the trucks!
Also, the MAT team only get an RPG-7, which is pretty pathetic.
I would suggest something a little bit more powerful, but maybe with only one shot? That way if you make it count, it COUNTS, but you're not tooled up so well that the bradley is just target practice...
