Wow what a thought provoking topic.
When I was a kid, I was into everything military. We played war games with sticks for guns and pine cones for grenades. I played many board games solo, because I couldn't find anybody interested in these long complex games. However, as I grew older I realized, as mentioned above, that I could get killed very easily and no matter what I did (on the battle field) my survival was only a matter of luck.
I still enjoy war games, chess included, because of the strategy involved in solving the problem of beating you opponent.
I am in awe of all veterans, because I know that I would never be able to do what they did to protect our country (and the world) from evil dictators.
Just last night, when I was in my back yard throwing out the Christmas tree I imagined I was in the Ardennes on patrol. That must have been a terrifying experience. Every step on the frosty ground might reveal a hidden mine that blows you to bits or a German ambush. I do not know how the veterans and current soldiers do it. The fear must be paralyzing.
