Military Assault Command Operations was a 22nd Century United Earth organization formed as a military defensive/security force. All MACO troops attended West Point Military Academy in New York, North America. They provided security services aboard the Enterprise NX-01 on its mission, proving crucial to its success in several skirmishes and battles against the Xindi between 2153–54. A “may-ko” soldier was well equipped, even ahead of their Starfleet comrades, with armor and weapons at the cutting edge of United Earth technology and design. —Operations Division Supplement, 95
