 Purpose of this exercise is to help meet some of the training requirements for our gunners to make sure that they're proficient in firing a Stinger missile, also incorporating quick reaction drills and support by fire positions utilizing the Stinger Cal. In the event that uh that there should ever be a time where the United States has an air threat against them or we have not yet established their superiority, we want to make sure that we have gunners on the ground that are able to eliminate that threat. Out here today we utilize both the Stinger missile and the Stinger Cal of Ortinga. The Stinger missile obviously for air defense we're able to eliminate any air threats that were coming towards our simulated convoy by utilizing quick reactions. We also have the Stinger Cal out there for any ground threats that we had simulating a support by fire type position while the Stinger came engaged in the aircraft. It's always good to get a real miss on your shoulder, an opportunity to actually fire even though they are remote control aircraft it is still an aircraft flying up there and it lets them go to the fundamental to firing that missile. I'd say the biggest thing that they've gained is the experience, the ability to actually feel that adrenaline, be able to pull that trigger and actually watch effects on targets.
