A1: Not sure about a regular will, but you can get a living will through the VA for free. (HO) 6/27/18

A4: If you are a veteran in the VA healthcare system, you can get a will done at the VA clinic or hospital in your area. (AP) 6/27/18
A5: It depends...try and find a proficient attorney in each state where you own property (both in real estate and financial) knowledgable about changing law (especially "order of succession" for bequests and debts).
I am not sure about free will preparation on board a military installation, eligibility and all that. Costs of preparation vary depending on the amount of property you (or within a Trust) own, as that property needs to be eventually represented both on paper and in probate court, if necessary. Most attorneys with whom I work typically offer will preparation at a reduced cost, if only to service their client and their family with other eventual products, as a "foot in the door." so-to-speak.
Another item to consider--which many attorneys overlook-- is your "digital legacy" (think "web-based" activity, like banks, emails, 401K/IRAs and similar). It all depends on how much you want your executor to know and handle.
Find and copy your DD-214--page4 (it can be placed on your smart phone for ease). Also make a list of VA phone numbers for your family to follow. If you're not married, ensure your will specifies who can retrieve and control your corpus, say, for cremation. Place a copy of all this paperwork--as they're revised-- on a usb flash drive
Hope these ideas help...(RB) 4/10/20
A6: You should be able to find a basic Will on the internet, look for one that fits your needs. Be sure to have it notarized, and share a copy with someone like your beneficiary or executor you trust. (MB) 9/15/20
