I'm a disabled vet also, and can give you info on 2 exceptional hunting opportunities.  First is the Idaho Disabled Veteran Special Permit.  This is a OIL permit where you pick the species and unit you want to hunt and if selected, you get a free permit. Not discounted, free.  I pulled a moose permit this year and will be heading out in 2 weeks.  The second opportunity is Wyoming Disabled Hunters. This is a non-profit organization dedicated to providing hunting opportunities to disabled people, with a separate category for disabled vets .  I just go back from a cow elk hunt on a private ranch where I took a nice cow.  All you have to do is get there; they provide housing, food, guides, tags, and any special equipment you may require.  Feel free to PM me for any additional info.
