 I'm with the 28th MP company and we've been conducting annual training. Today we're doing the IED lane and we were reacting to an IED. IED is an improvised explosive device. They're used by the enemies to disable our vehicles and take out personnel. I was the gunner on the second truck in the convoy. The first truck spotted the IED on the right hand side of the road. My job is to help relay information to the other trucks and just to maintain sectors of fire to make sure nobody enters the area and wait for EOD to arrive. On the left hand side of the road, not in my sector fire, we received small arms contact. There was an overpass that we went under and while going under the overpass we received small arms fire from on top of the overpass which I returned fire and eliminated them throughout. It was a fun experience but extremely humbling. When you're actually going through it, it's a lot of people with a lot of different responsibilities. Great coordinates for the LC. Great coordinates of where we're located, our routes, positive identification, and our roles and engagement. I'm a more hands-on learner so this experience definitely helped going through and seeing how the parts should be moving.
