5/5 beat the game first try what i did is: Use M1A1 Thompson (first gun) until you have have enough for the BAR repairing you're fort fully after every round. Than use the Bar until you have enough for the browning repairing youre fort every roung. Than use browning and get a bazooka use the browning than when you see some vehicles switch to the bazooka shoot them switch back than like 8 secs. l8er switch backa and repair your fort FULLY after EVERY ROUND.hope i helped
