A Slovenian Valuk, a light wheeled armored vehicle, provides security during a live-fire exercise as part of Exercise Rock Sokol at Pocek Range in Postonja, Slovenia, March 3, 2016. Exercise Rock Sokol is a bilateral training exercise between U.S. Soldiers assigned to 173rd Airborne Brigade and the Slovenian Armed Forces, focused on small-unit tactics and building on previous lessons learned, forging the bonds and enhancing readiness between allied forces. The 173rd Airborne Brigade is the U.S. Army's Contingency Response Force in Europe, providing rapidly-deploying forces to the U.S. Army Europe, Africa and Central Command areas of responsibility within 18 hours. The brigade routinely trains alongside NATO allies and partners to build stronger relationships and strengthen the alliance. (U.S. Army photo by Visual Information Specialist Paolo Bovo/Released)
