i got to wave 110 with this... wait till you hav 15 points, then get signaler. get parachute units. they are usually armed with good weapons and have a good rifle skill above 30(mostly). train an officer, than a jeep. afterwards get an engineer and make 2 bunkers. make a minefield in the middle of the map, preventing the germans from crossing...for a while anyway. build 2 mortars, than upgrade weapons. Then go nuts!!
