Programs whose members are veterans who have joined together on a voluntary basis to promote mutual interests. Activities may include advocacy for the preservation and expansion of earned privileges and benefits, testimony before Congress on issues affecting veterans, awards and other measures for promoting appreciation of and recognition for veterans and their accomplishments, community service programs, and social activities for members. Some organizations may provide active support for the democratic principles of religious and political freedom; offer benefits such as health insurance, life insurance, credit cards and financial planning services for members; or maintain special burial funds to help indigent veterans and their families.
