U.S. Army Spc. Barrett Deisher, paratrooper, 3rd Platoon, Company D, 2nd Battalion, 503rd Infantry Regiment, 173rd Airborne Brigade, clears a stairwell in an abandoned building during a bi-lateral training event with the Polish 6th Airborne Battalion, 16th Airborne Brigade (not pictured), in an urban operations training facility in Wedrzyn, Poland, Nov. 21, 2016. A part of the mission throughout Eastern Europe for the 173rd Abn. Bde. is to help strengthen the NATO Alliance. This is done in part by enhancing Allies' light infantry tactical capabilities by sharing tactics and training techniques and procedures. The integration of this goal into everyday training is the key to success for the unit during its rotation at Atlantic Resolve. (U.S. Army photo by Sgt. William A. Tanner)
