“They left me out there for a while, but they gave me a morphine drip, so I didn’t complain,” Sargeant said Saturday at the culmination of a seven-hour mass casualty drill. The exercise involved moving 55 “victims” from a propane blast at the Fort Seward parade grounds to a seven-tent mobile hospital near Third Avenue and Main Street.
