One of the free things on my website, is a format for a 12 step group for veterans and families and friends. Recently I have gotten two phone calls from veterans who have been in 12 Step programs for 20+ years who are interested in starting Combat Veterans Anonymous. I hope it happens.
I wrote the format for Vets and Families, but like AA and Alanon, I think the two groups would do best to be separate. There are three or four other things on that page related to the 12 steps, too.
I am in a couple of 12 Step programs and find them really helpful in dealing with life, the universe and everything...
