The U.S. Army has begun to test four platforms that work to protect combat vehicles from anti-tank guided missiles and rocket-propelled grenades, Defense News reported June 29.

Jen Judson writes the service branch considers three active protection systems from foreign companies and one platform from a domestic firm for integration with Stryker, M1 Abrams tanks and Bradley Fighting Vehicles as part of the Modular Active Protection System program.

The Army plans to deploy the APS as an “interim” platform in an effort to address the operational requirements of warfighters in Europe, Judson reports.

Katrina McFarland, Army’s acquisition chief, told Defense News that some of the APS that the service branch considers for its fighting vehicles include Israeli Military Industry’s Iron Fist, Artis’ Iron Curtain and Trophy from Israel-based Rafael Advanced Defense Systems in partnership with DRS Technologies.

The report said the military branch also plans to integrate Rheinmetall Defence’s Active Defense System with its combat vehicles.
