 Today, one of the big major lessons learned is how we would do interoperability between a U.S. engineer from UNIT and a Slovenian tank platoon. It's very good, you got a lot of experience, you learned a lot of new things and some old things. Well, today they're digging up our defense positions, so we'll be in the defense and try to destroy our enemy. We showed the plan, we showed what we recommend to do based on our understanding of the terrain and how the engineers would want to dig in positions. It's important because when we push the spoil of what we dig, it's concealing the whole obstacle. So if it's in the second tier and you're driving past, you're not going to see that tank. And by the time it goes up to the first tier, it's already too late. It's pretty cool seeing the stuff we do that they can use it to the best of their ability and we can alter it to however they want, whether they want it deeper or shorter. It's pretty cool actually. Every training, even though you did it a hundred times, a thousand times, it set up some new information of your preparation and your tactics. So overall, what a great opportunity for U.S. engineers to pair and partner with a Slovenian tank platoon to conduct a defense and then together we were able to accomplish the mission together and complete the objective together.
