Qwai River, Chinese APC firing out of Main

for about half an hour now the Chinese APC squad is firing out of their main, i destroyed one of their VN3s with the HAT but apart from that i cant hit them, im on the US team and i dont know their names and the game should be over soon, also i suspect one of the Chinese APC gunners to Hack since he was behind a hill and he shot and hit me throught the hill (could also be some PR texture glitch that doesnt show the vehicle to me)
Edit: the Chinese APC squad ended up best squad, names are
Squad lead:
