Ranger, the A-4Mike missed Vietnam.
Marine line units received A-4M on the following dates.
VMA-211 September 1976, El Toro
VMA-214 Early 1973, El Toro, first deployed to Japan July 1977
VMA-223 May 1975
VMA-311 Established September 1974 with the assets and personnel of fromer VMA-324
VMA-324 April 1971 (first A-4M unit), deactivated August 1974, no Oriental deployments
VMA-331 1971, Beaufort, first deploying to Iwakuni Japan in 1980
all the remaining A-4M squadrons were USMC Reserve squadrons, so those did not deploy, either
Closest an A-4M USMC unit came to deploying were the weapons deployments and the CarQuals
hope this helps
