Fireteam 1. immediately after touchdown our machinegunner informed us of a problem on his Sound system, he could only hear TS, I decided to keep him on but stay on a supportive role in the mission, however after taking heavy losses at RP1 (we lost sam, our MG) we had to step up, the mission was confusing to us until we moved from the RP1 to 2nd AA position. there we were ambushed by 2 enemy LMGs and a couple riflemen luckily Fireteam 4 aided us and we took only 1 casualty and 2 wounded. By this time the rest of the fireteam 3 had emerged with us. after dealing with the ambush we took out enemy Tunguska, we got ambushed again and lost 100% of our manpower.
