Play the first mission, "Afghanistan Operation Swift Caravan" in Terrorist Hunt mode under the easiest difficulty setting. Having two characters with flashbangs, two breach charges, and a UAV will make this easier. Use the UAV at the start to learn where the enemies are located. Breach both entry points with charges, clear out the first two rooms, and try to position your squad members away from line of fire of the other two rooms to prevent incoming fire if terrorists appear from them. Toss flashbangs into the other two rooms, then send the non-flashbang thrower into the room to clear it.
