American troops must ready themselves for combat not only in Earth's orbit but in the region surrounding the moon, according to President Donald Trump’s top military adviser on Wednesday, following the first public revelation that the U.S. has deployed weapons in space.
Addressing military personnel and defense industry leaders at the Air, Space and Cyber Conference near Washington, chairman of the Joint Chiefs of Staff Gen. Dan Caine urged the armed services to adapt so the military "is prepared to fight, endure and win ... from the seabed to cislunar space."
