Jimi Hendrix was not a paratrooper.
I thought it was interesting so read several short biographies. A couple said he entered paratrooper training but was injured and given an honorable discharge.
Others indicate he was discharged for less than honorable reasons.
Either way he served either less than a year of about a year. His biographies are really all over the place. It would probably be difficult to get a straight story about him.
I have spent a lot of time in the past trying to pin this down precisely, and unless you can come up with a good and solid source, we have to assume that he was Airborne.
Many sources credit him with 25 jumps by 1962, and Wikipedia describes him as completing jump training.
There is no question that he was booted out in time.
