Military of Puerto Rico

The military defense of Puerto Rico is the responsibility of the United States as part of the Treaty of Paris. Locally, Puerto Rico has its own National Guard, the Puerto Rico National Guard, and its own state defense force, the Puerto Rico State Guard, which, by local law, is under the authority of the Puerto Rico National Guard. The commander-in-chief of both forces is the governor of Puerto Rico, currently Ricky Rosselló, who delegates his authority to the Puerto Rico Adjutant General, currently Brigadier General Isabelo Rivera The Adjutant General, in turn, delegates the authority over the State Guard to another officer but retains the authority over the Puerto Rico National Guard as a whole. At the national level, the commander-in-chief is the President of the United States, currently Donald Trump.

A branch of the U.S. Army National Guard is stationed in Puerto Rico —known as the Puerto Rico Army National Guard— which performs missions equivalent to those of the Army National Guards of the different states of the United States, including ground defense, disaster relief, and control of civil unrest. The local National Guard also incorporates a branch of the U.S. Air National Guard —known as the Puerto Rico Air National Guard— which performs missions equivalent to those of the Air National Guards of the U.S. states.
