 So, recently what we did was we worked with the Dutch Royal Navy and the Dutch Royal Marines. What we're doing was loading the AAVs onto their landing craft utility vessel and crossing a fjord and just working with both us and the Dutch and pretty much just seeing if we were able to even get AAVs loaded onto their platform and be able to cross utilizing their resources to cross the fjords. We then utilized the Dutch ground guides in order to load the AAVs onto the LCU. Once they are loaded onto the LCU then we went ahead and crossed the fjord, landed, and then offloaded the AAVs onto the roads. And then from there it was just a round robin process, went right back on the LCU utilizing the Dutch Marines and then crossing back again. We did that several times. The challenge would really be just the language ability. They use the metric system and we use a different system as far as weights and measurements so that can create uncertainty to a degree just because if I tell them a certain weight or length it's going to be, we're going to have to convert it. I'd say the biggest takeaway was just the interoperability amongst us and the Dutch Marines enjoyed that as well as the Dutch so we just built some good ties with that and I know some of the Marines have just made friends out of that.
