Arm 5 Conscripts or any units except crazy Ivan.arm the only 1 by one.which means do it like you arm a unit and put it in a flak track and arm another 1 and place it in a flak tack and so on and so forth.then just send the flak track beside an enemy building and disembark.its going to be a lot stronger if you made 4 flak tracks and place them in the 4 sides and disembark.but in case it wont work use a conscript.
