The USO Show Troupe performs at the U.S. Marine Corps Reserve Centennial celebration in Times Square, Aug. 29, 2016. For 100 years, the Marine Corps Reserve has answered the call, serving as our nation’s crisis response force and expeditionary force in readiness. The centennial commemoration is a way to honor this selfless service and celebrate the Marine Corps’ rich history, heritage and esprit de corps. It also provides an opportunity to thank their families, employers and community for their continued support. (U.S. Marine Corps photo by Sgt. Sara Graham)
