So the Skoal chewing machine gunner he writes about - Lee James Stoker - was my "Drill Sargent" in basic training in Israel. They're not DIs in the US sense but he was papa for that time period. A good guy, honest, patient and skilled. One of ours also chewed and they kept each other in smokeless. At our passing out parade we did a group (western immigrants) shew-spit at the appropriate moment. The sabras (native Israelis) never took to the stuff. He never gave us too many details about his Lebanon time; it was all 3rd party.
