Membership in the men's auxiliary is open to men and boys 16 and older who are the husbands, widowers, fathers, grandfathers, sons, grandsons, brothers and half-brothers of eligible VFW members.
In 2003, members of V.F.W. Post 7666, Guilford, Connecticut, made a motion to amend its by-laws and sponsor its own Men’s Auxiliary. The motion carried, with 100% of the members present voting in favor. On May 21, 2003, the V.F.W. Post 7666 Men’s Auxiliary was officially chartered.
