 Evolving from test units, ARA gunships (along with those assigned to lift companies and air cavalry troops) provided a source of supporting fire in Vietnam known for its "flexibility, accuracy, and immediate response" to any combat situation within range.The AH-1G Cobra was a direct result of the successes of the early armed UH-1Bs and UH-1Cs and remained in service after the last ARA battery was decommissioned.In 1970 the designation ARA was changed to AFA (Aerial Field Artillery).
