 17 NATO allies and partners came together to plan and execute one of the largest northern European exercises in the Baltic Sea. This year's operation took historic steps, when U.S. Marines, transported by the joint Finnish and Swedish Newland Brigade, arrived at Sindelen, Finland. It's a win-win situation, NATO, U.S. troops, and Finland, Sweden, all exercising together. This is the second time in Baltic history when you have amphibious troops and landing force in this exercise. Corporal Chase Grenier, with the U.S. Marines 38 India Company, out of Camp Lejeune, describes his experience in Finland. They're very welcoming, very respectful people, and they've led us land in Finland on their own Finnish U-boats, and that was a cool experience to ride on those boats for the first time and see the technological advances that they've made in warfare. They seem just as disciplined as we can be, and they seem like they're ready to get into a real-world situation and be capable of handling anything that comes their way. U.S. Marines will continue to train alongside NATO allies and partners for the duration of Baltops 2016 throughout northern Europe. Reporting from Hanko, Finland, I'm Petty Officer Rebecca Sunderland.
