Imagine being found unsuitable for military life... 
and mustered out!
Intersting time for the military, interesting for me to think back and remember those times. The draft during the Vietnam era brought a lot of undesirables into the services. That was OK with Big Brother though, they had lots of body bags to fill over there.
Some recruits were undesirable for many reasons that varied widely, but not necessarily for intentionally not following the UCMJ, etc. More often for personal habits, laziness, just plain too uneducated (or downright dumb) or not physically able fit some of them. And some of them "faked" same so they could get out in boot. So mustered out was common enough in boot camp when I was there in 1967, and they usually got an AELS discharge, neither honorable or dishonorable, unless for just cause to get a punitive DC, BC or GOTH.
I remember a few who were mustered out simply because they couldn't do the basic requirements of boot. Many of those were Filipino's who sign up for a 6 year hitch in the Navy to gain US citizenship. They did nothing legally wrong, actually tried very hard... but just couldn't make the grade. Most got AELS discharges I think. I remember one in particular, Arturo Aurora (spelling?). Remember him both because he was quite small and thin unlike most of the other Filipinos, and because he was the best in the company and battalion when it came to drill and inspections, was always in the top 10% on written tests. As the RCPO of the company I called on him often to help others struggling in our company with military requirements. Very sharp guy, very hard working, and very well liked in our company. But he just couldn't pass any of the water tests... basic swimming, floating with a PFD made from his clothing in the water, or the high tower jump. Out of the ordinary he was allowed to try several times, our CCO and BCO really wanted him to pass. Being on a ship would have been out of the question for him, so they finally had no choice but to send him to SEPS. Pretty sure he got a GUHC instead of the AELS simply because he was an exceptional squirrel otherwise.
After boot a discharge for undesirables or for just cause was more often either an AOTH, DD or BC. Which makes Jimi's honorable discharge as an undesirable "interesting" to me. Probably should have been a GOTH.
Matters not, he accomplished more, did far more good as a musician than he ever would have as a soldier IMO.
