In 2011 I was deployed to Afghanistan. During our first mission we searched some caves that were believed to be used by insurgents prior to attacking our MOB, my Military Working Dog and I went through the caves and cleared them with no issues. We then continued on down a footpath for roughly 800 meters before finally heading back to our waiting vehicles. Before we got into our vehicle I decided to give him the opportunity to take a break (i.e., piss) while he was doing his thing he showed a distinct change-of-behavior and began bracketing towards a n area our search wasn't focused on according to intel. I followed him and he made his way to a firing pit roughly 6' deep and 5'x7' in width and length. He pinpointed on the side of one of the walls and hastily buried in the wall were 9 mortar rounds, in the bottom of the pit were four rockets. The firing emplacement was only 400 meters from the perimeter! After the countless hours of training my MWD had his first real find, knowing that we managed to prevent a few rounds from heading towards the base was a wonderful feeling.
