How did Kersey and Charlie meet during the Korean War?
If Kersey was a conscientious objector?
Was he just hanging out in war-torn Korea and happened to meet Charlie on his leave? Kersey didn't care for forced military service but but loved death and destruction and wanted to be where all the action was? Like an FU to the government? (You can't make me go to war! I'll go to the war on my own!)
Maybe they met back in the USA after Charlie's tour was over? That would almost be like me saying I met my good friend Jim Dangle during the Iraq war, even though we really met in a McDonald's bathroom in Nevada, but it did technically happen sometime during the 8 years of the Iraq war.
