I could really use a step by step process of volunteering for military service, specifically during the Vietnam War. I vaguely understand that young men would go to an army recruitment center (that seem to pop up more during war time?) and get a pre screening of sorts. A bit of a medical check like vision, weight, ect. They meet with a recruiting officer for an interview--

What would be some questions that would be asked? I get that generally it's questions like "Why do you want to join? What kind of career do you want out of this?" but I feel like during war time, when the army is pressed for men, questions like that wouldn't be asked? Maybe more direct and urgent, like what MOS they were interested in?

From there it's the MEPS? Or are MEPS and recruitment centers the same thing? And that's a more detailed screening, but I'm not sure what would be the difference, if there is one.

Then it's off to BT for six months, where they would be trained with a unit to be a soldier. Do units ship out and fight together? Or would you be re-assigned upon landing in Vietnam?

I'm sorry for my complete lack of understanding and thanks for the answers. There's so much on the draft during Vietnam but I'm having a hard time understanding the process that volunteers when through.
