Marshall Plumlee had been training his platoon for a week through combat scenarios with live ammunition, stumbling and learning until they completed the mission by blowing up a mine-wire obstacle with C-4 explosives. Plumlee, the former Knicks center, suddenly was hit with the same adrenaline rush he remembered at Duke, or the G League, or the NBA. “When I was able to help my squad leaders blow up that obstacle, in that moment, it was like the same as dunking on somebody in a basketball game,” Plumlee tells the Daily News. “It was a pretty surreal experience.”
