The Navy League’s online edition of Seapower Magazine reports that an “Advanced Interdiction Team” [Army, Navy and Coast Guard] from the destroyer USS Winston S. Churchill (DDG 81) had seized weapons found on two stateless dhows off the coast of Somalia.
“The cache of weapons consisted of thousands of AK-47 assault rifles, light machine guns, heavy sniper rifles, rocket-propelled grenade launchers, and crew served weapons. Other weapon components included barrels, stocks, optical scopes and weapon systems. “

Maybe the Army is there to recognize the origin of the weapons.
