receiving antenna in 17-mission 2. Intel is on the second floor. 2 in the way to follow the captain

You will see a temporary camp full of terrorists, on the platform consisting of a bunch of huge barrels next to the two enemies on the mouth of the Mac captain said "boo". To get the intel, either sneak away or take out all the enemies. Note: Do not want to go over and then come back to take 21-branch mission 2 in the truck under the sneak to a building, a sniper guarding the fire escape.
