question for anyone... ok I killed everything blew up both tanks an now it tells me to cover fire for the CHA soldiers... I cover the area but I can't get the soldiers to move... what am I doing wrong? please help thanks...

hey dude. im havin probs with that screen too. ive beaten it b4 but my memory got erased a few months ago so i just recently started all over. ok, u r supposed to be able to go up to the soldiers, open ur command menu and a "CHA soldier" tab appears under the fireteam, able, bravo tabs. go into that and there is an instruction to tell the guys to clear out. ive been able to get the guy in the church out but everytime i get to the guy laying down in the middle of the court area, its not letting do anything else. plus how the he*% do i blow up the tank that is parked and bunkered in and the anti aircraft gun? i seem to remember placing a sachel on the anti aircraft gun but it wont let my command any of my boys to place the sachel. do i have to be in a specific place or something? and ive never figured out how to get into the bunker surrounding the parked tank....any help?
