The OH-6 Cayuse was quickly nicknamed the 'Loach' after its initial designation LOH (Light Observation helicopter). Its high speed, maneuverability, and small size made it an excellent scout helicopter, even though much of its work was done at low speed while flying at or below treetop level.
Armed with a M134 minigun and a M60 machine-gun, the OH-6 Loach could still deliver a nasty sting of its own.
