If he's only an Gulf War era Vet, he won't qualify for the VFW. Hubby is Vietnam era Vet, and can only join the AM Legion.
Gail, if your husband was in combat in Viet Nam then he most most certainly can join the V.F.W. !!! He should have received a Viet Nam Service Medal for combat service.
Here is the link for all those eligible veterans who have received a combat action ribbon for service overseas, who can join the V.F.W.
Viet Nam Service Medal
July 4, 1965 until March 8, 1973
