Tank and maintenance crews with 1st Battalion, 66th Armor Regiment, install reactive armor tiles onto a M1A2 Abrams tank at the 7th Army Training Command's Grafenwoehr Training Area, Germany, Feb. 28, 2017. The installation of the Abrams Reactive Armor Tile system will enhance the tank's defensive capabilities, providing a greater deterrent against aggression as the 3rd ABCT maintains a persistent presence in Central and Eastern Europe as the rotational ABCT for Atlantic Resolve.
