Soldiers from U.S. Army Europe's Alpha Battery, 5th Battalion, 7th Air Defense Artillery Regiment, familiarize members of the Polish military on how to conduct preventive maintenance on the Patriot missile systems in Morag, Poland, June 1. This is the first time a U.S. missile system has come to Poland for a new rotational training program intended to familiarize Polish armed forces on the Patriot Missile system. The training is designed to provide mutual benefits for improving Polish air defense capabilities while also developing the skills of U.S. patriot crew members. This type of mutual training helps to expand U.S. and Poland air and missile defense cooperation while helping to strengthen the partnership between the U.S. and Poland.
