“It can do just about everything…” The USS Iwo Jima Amphibious Ready Group and 22nd Marine Expeditionary Unit have proven crucial to the success of recent operations in the Caribbean as part of #OpSouthernSpear. During testimony March 19 before the Senate Armed Services Committee, #SOUTHCOM Commander Gen. Francis L. Donovan told lawmakers how invaluable the Navy-Marine Corps team has been on a daily basis, demonstrating its lethality, precision and superiority to regional friends and foes alike. @USMC @MARFORSOUTH @22nd_MEU @USNavy @NAVSOUS4THFLT @DeptofWar @SecWar @iimefmarines

Applying total systemic friction on the cartels. On March 25, at the direction of #SOUTHCOM commander Gen. Francis L.

Four male narco-terrorists were killed during this action. No U.S. military forces were harmed. @DeptofWar #OpSouthernSpear
