President Trump on Tuesday said he was considering adding a sixth branch to the U.S. Armed Forces that would specialize in military action in space: the Space Force.

“You will be part of the five proud branches of the United States Armed Forces: Army, Navy, Marines, Air Force, and the Coast Guard. And we’re actually thinking of a sixth, and that would be the Space Force,” Trump said when presented the Commander in Chief Trophy to the U.S. Military Academy football team in the Rose Garden.
