Welcome, BB, to JWD. That's quite a first post.
First, thanks for your research and work—that was no small task!
A few thoughts and observations:
1. Could you put together a condensed version? You would get more people watching it if it were 30-35 minutes rather than nearly 1 hour and 19 minutes.
2. Why did you choose AM II/III and not some other GB member? Is it because more public records are available for him than the others?
3. Any plans to do this with other GB members?
4. Some thoughts on AM's military/Viet Nam service. At that time an enlistment was 4 years of active duty whereas the draft was 2 years. Most draftees went into the army rather than the other services (but admittedly in practice that was somewhat arbitrary). I know one veteran who came back from SE Asia on a huge Medivac flight, a C-140 flying hospital, with men being operated on during the flight over the Pacific, some even dying on board. He said that about half the patients on board were diseased rather than being injured in battle. That's how common getting sick over there was. Some had come down with the very diseases they had been vaccinated against before leaving the USA. Others had diseases that were never fully diagnosed. AM worked in a hospital and was exposed to a large variety of sick patents. Even today in a hospital in far healthier conditions than one in a tropical jungle, nurses, orderlies, and techs often become ill from treating patients, and patients come down with diseases from fellow patients. So I think it's unwise to conjecture why AM became ill.
On a related but really different point, if AM had not wound up sick, we might be able to conclude that he was drafted rather than having enlisted, given his 2 years of active service (but he could have been medically discharged as an enlistee). However, if his being an elistee were the case, we might expect a disability from the VA, perhaps a partial one, common during Viet Nam and still practiced today. Furthermore, the US military is not eager to discharge someone who has two years left on their commitment. After all, they have invested thousands of dollars in that one's training. In sum then, it looks more like AM was a draftee than an enlistee, IMO.
Thanks again for your work.
