acronym for light observation and attack chopper. Quite possibly the best chopper to grace the skies (nothing against the cobra). Also also known as the OH-6 and developed into the Hughes 500 civilian version. Frequently used in hunter killer missions in Vietnam. The loach would fly low drawing ground fire from VC dumb enough to shoot at it, then magically maneuver out of harms way allowing the cobras and Huey gunships to light the place up like a Christmas tree. Later adapted into the AH-6 Mh-6 little bird(that the special forces still know, love and use)denoted by it's horizontal rear stabilizer rather than the loach's Y-shaped tail. With it's own chain guns and rockets it was more than capable of unleashing hell from above.
The VC shot ground fire at the loach, hope they like napalm and hellfire missiles cause it's Charlie's ass now
