History
The 4th Low Altitude Air Defense Battalion traces its origin back to 1 October 1972, when the 4th Forward Area Air Defense (FAAD) Battery was activated as a combat support unit under the 4th Marine Aircraft Wing. From 1972 to 1988, 4th FAAD Battery consisted of (4) Firing Platoons and a Headquarters and Service platoon. FAAD teams employed the Red Eye shoulder-launched surface-to-air missile and used the M1A1 Jeep for missile transport and tactical mobility. In 1988, 4th FAAD Battery transitioned from the Red Eye and Jeep to the Stinger surface-to-air missile and the Humvee.
On 1 July 1989, 4th FAAD Battery was re-designated as the 4th Low Altitude Air Defense Battalion and was assigned to Marine Air Control Group 48, 4th Marine Aircraft Wing. The re-designation increased the size of the unit from four platoons to a Battalion headquarters, one Firing Battery and a Headquarters and Service Battery. At that time, 4th FAAD Detachment Alpha in Marietta, Georgia, was also re-designated as 4th LAAD Battalion, Detachment Alpha and increased in size from three platoons to a Firing Battery and a Headquarters and Service Detachment.

Why this record matters
The phrase “military unit” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Mar 31, 2024. The linked authority identifier is Q4639337. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1972, 1988 and 1989.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
