Helicopter Attack Squadron Light
The "Light Attack" (HAL) designation was created in 1967 when HC-1's attack helicopter detachment was established as a separate squadron HAL-3. In 1988 the functions of the two Navy Reserve Light Attack squadrons were merged with the function of the single Navy Reserve Combat Search and Rescue Squadron (HC-9) the two light attack squadrons were redesignated to "Combat Support (Special)" (HCS). The HCS designation remained in active use until 2006 when one of the squadrons was redesignated to Helicopter Sea Combat (HSC) squadron and the other was deactivated.
