 Here at the Novo Selo training area in Bulgaria, soldiers from three partner nations are learning advanced infantry tactics with U.S. Marines. Check your left, check your right again. Back bless, clear! Rocket! U.S. forces have been training with Bulgarians, Romanians and Serbians every day for the past week at Exercise Platinum Lion 15. Hey, good job, guys. I hope you enjoyed it. It's amazing. No problem. Improving military effectiveness of U.S. partner nations is a top priority for the Marine Corps, as Defense Secretary Chuck Hagel told a group of Marines earlier this week. We'll help, we'll support so that they have capabilities. They have the capacity. They have the institutions to defend themselves. Hagel described U.S. service members as both warriors and ambassadors, and Marines from Black Sea Rotational Force have worked to exemplify this idea since 2010. When you're done firing, you flip it back down. It's not about us training them, it's not about them training us, it's about us training together. It's about learning who these people are and building relationships for the future. So it's pretty neat to see a lot of these people that we've worked on prior exercises with come back here and we get to further our relationship with them. My name is Dimitri. Dimitri, yes. Nice to meet you. Nice to meet you. This platinum line will offer plenty more opportunities for building friendships as Marines live and train with soldiers from partner nations. Reporting from Bulgaria, I'm Sergeant Russell Midori from Marine Forces Europe and Africa.
