This is an old post, but I thought I would join in.
To me, there is a big difference in being involved in a war and joining the service. I was never in the service. At the time when I was 18 there was a war on, and I was afraid of being injured, not killed. I knew a lot of guys brothers who we injured. I was not an Adventist till many years later.
I later learned the on 20% serve on the front lines, 80% are logistics.
The one regret I have is that I did not at least try to join the service. I think a few years of taking orders and obeying, would have been good for me. And the benefits are terrific.
I know a guy from a family that could not afford to send him to college. He joined the service as a diesel mechanic. Served his time and got a great job after.
