 So, the last two days we've been out in the training area and we've been doing some demolition training. Today we had no vehicles to be able to get out there so we decided hey, we'll do cold training. We'll break the robot out, practice how we would use it with actual charges. We figured we'd get them in there, get some time on the robot itself and try to do the harder things with it. The Tunisian UD may not have the same equipment we have and they still manage to get the job done just as well. So, getting to see how they do it, it just gives us different tools to put in our tool belt. They have been very willing to learn. They ask engaged questions. They're very focused on the training once we get them out there. It's been a solid exercise. There's been a lot of rounds fired, a lot of training. It's been pretty much wake up every day, get training in and then wake up and repeat. Do more training, different training every single day.
