We need your assistance! Our current top priority is to assist the Fort Sam Houston Caisson Section with replacement horses. The Fort Sam Houston Caisson Section is one of only two active duty, full time caisson units in the Army. The Uniformed VMA has assisted with raising funds for the purchase of several horses but still needs your assistance in raising funds for additional replacement horses. The Uniformed VMA is a 501(c)(3) corporation, all dues and donations are tax deductible. Donate today!
