I worked the towers. Closest to combat for me were situations where a few of us nearly got hit with a stray bullet while walking on the compound, the time an IED was dropped in a blind spot and a humvee hit it, a mortor hit not too far from where our bay was, and other various explosions that were too close for comfort, such as the time a suicide bomber tried to take out the tower closest to the wall. Said tower was the next tower over from the tower I was in. But regarding having to fire my weapon, I didn't get the chance. I was just in positions where I had to prepare to lock and load.
