United States Army Sgt. Brandon Griffin, a 23-year-old native of Tyler, Texas, right, assigned to Team Eagle, Task Force 2-7 Infantry, listens to Portuguese Army Sgt. Maria Campino of the Cavalry Regiment No. 6, Reconnaissance Squadron, Intervention Brigade, explains how her own Leopard 2A6 Main Battle Tank is very similar in design and function to Griffin’s Abrams M1A1 tank during Unity Day held at the Great Lithuanian Hetman Jonusas Radvila Training Regiment, in Rukla, Lithuania, May 15, 2015. Unity day brought together multinational armed forces and the local populace of Rukla for a parade and static display of weapons and vehicles. The Soldiers of Team Eagle are part of Operation Atlantic Resolve, an ongoing multinational partnership focused on joint training and security cooperation between the U.S. and other NATO allies.
