[Colonel]

The comm tower is the last level. The way I did it, after getting killed several times in a row mad: , is to kill the first couple of guys that come up to set the bomb from the balcony. Then I ran down to the next level and sniped by leaning around the edge of the arched window. I didn't worry about killing all of the guys, I would just snipe the guys setting the bomb. As soon as you hear the tank coming, run back up to the balcony and snipe another guy at the bomb and then go to the radio so you can send the signal as soon as he yells for you to.
