The Boeing (McDonnell Dougles) (formerly Hughes model 369) OH-6A, was designed for use as a military scout during the Vietnam war to meet the U.S. Army's need for an extremely maneuverable light observation helicopter (LOH program). The Hughes OH-6A Cayuse was quite effective when teamed with the AH-1G Cobra attack helicopter as part of what were known as 'Pink Teams'. The OH-6A 'Loach' would find targets by flying low, 'trolling' for fire, and lead in a Cobra, or 'Snake', to attack. The OH-6A could be armed with the M27 armament subsystem, the M134 six-barrel 7.62mm 'minigun' or the M129 40mm grenade launcher on the XM8 armament subsystem.
