Alvin Holsey, the Navy admiral overseeing military operations in the Caribbean, will retire in December.
Holsey, who leads U.S. Southern Command, has been in his position since November, overseeing an area that includes the Caribbean Sea and waters off South America.
The news of his retirement comes two days after the U.S. military's fifth deadly strike in the Caribbean against a small boat accused of carrying drugs.
The Trump administration has asserted it's treating alleged drug traffickers as unlawful combatants who must be met with military force.
Frustration with the attacks has been growing on Capitol Hill.
