My uncle did 5 years hard time in prison during WWII. He was a gentle soul and suffered brutal treatment. He was never the same after his release. I'm sure he suffered from PTSD among other serious emotional problems. His younger bro. enlisted and became the family "black sheep".
A number of friends and family went to prision during Viet Nam. However, the conditions were not as bad as during WWII. The ones i knew went to Safford Az where the JWs got to be together and usually went home in 18 months or less. The Lottery saved my 1st hubby. He drew 360 out of 366 in the 1st round. He quit pioneering the next day. LOL
Like someone said, Pioneering helped much more in WWII than Viet Nam to get a minesters classification. I still have the "Consolation" mag from 1941 that listed the names of the brothers who the WTS helped to get their minesters classification. My father, my stepfather, his brother, hubbys uncle etc. etc were all listed.
