I am stuck on level 5 I just destroyed the fuel tanks and cant find where to go to destroy the antennas with the C4.

thanks in advance we need this asap thanks!!!!!!!

The antennas are on the roof above the main frame. Hint have Conners standing near the front door with anti aircraft gun ready and Bradley standing next to conners as support against infantry. As soon as some one steps out onto the roof you will hear a gunship aproach have everyone retreat back indoors and then move conners out. The gunship will start to pummel Conners but you should be able to use him to take the gunship out with one shot from the antiaircraft rocket.
