Help! I can't get past the Radio Tower mission. Does anyone have any suggestions on how to get past it? It's driving me crazy! Please Help!!

i had trouble too....its pretty easy, wait for the bombs to come, then take cover. after that get onto the rightside of the ruins, ( where 2 of the 3 guys went) shoot a few of the guys (esp. the rpg) behind the rocks in front. Then follow instructions till u see the tower. Here is kinda hard. U HAVE to stay to the right of the rock and put obj A right in front of u, and have the rock covering ur left side ( u WILL get shot beacuse ur team will not shoot the '203 behind the rock' forever....shoot the guys in the building and then u have to peak around the rock at the guys flanking ur left....the rest is pretty easy, just follow the instructions
