Rapid Response Team 59

RRT-59 - the "Fifty-Niners" - were a Starfleet Special Operations unit stationed aboard the USS Monitor. They were involved in several covert actions during the Dominion War. Between 2374 and early 2375, their commander was Lieutenant Therav th'Shan.

By the second end of the war, the unit had become integrated more fully with the ship's tactical and security personnel, as the casualties mounted.

In 2374, the unit was infiltrated by a Founder posing as a squadmate. The Founder remained with the unit for some time before being detected, resulting in a sabotaged mission and the death of Assistant Chief Tactical Officer Lieutenant Enrique Mendoza by friendly fire. It is considered either heroic or lucky that half of the team survived.
