Alright all you need to do with this level is send every thing you can thru the middle.(do not concentrate on the flanks.) Start with rifle men,an assault squad and a machinegunner. Then send reinforcments thru the midle as they move on. Tip:they will most likely send a mortor team out first,so keep your men moving. And watch for bazooka teams as they will do the most damage to your mass of troops.
