I volunteered, twice. Once to enter boot camp at Lackland and the 2nd time when they asked who was volunteering to go to Viet Nam. My MOS was frozen for Nam but I stepped forward anyway. I didn't go, didn't even serve active due to my health however I was ready and willing but less than able according to the AF doctors. I tried contesting it with my Representative but he warned me that if I made too big of a stink I could end up with a General rather than Honorable Medical, so I caved.
