HMM (Marine Medium Helicopter Squadron)

The first H means helicopter; the M means Marine; the M means medium. (NOTE) The three numbers following these letters usually identified the original parent Marine Aircraft Group and the sequence in which the squadron was first commissioned. HMM-161 was the first squadron commissioned in MAG-16. HML-367 was the seventh squadron commissioned in MAG-36. There were exceptions. HMH-463 was not the third squadron commissioned in MAG-46. MAG-46 did not exist in the active force structure. it was then and still is a Marine Reserve Aircraft Group. As a wartime expedient both HMH-462 and HMH-463 were commissioned in other aircraft groups and, when operational, were transferred to MAG-36 and MAG-16 respectively.
