That guy has always impressed me. But another thing I always think about is the soldier driving the tank. He was likely drafted and forced to go against his own people. That had to suck.
just for the record... once the tanks were in place, there were as many or MORE tubes pointed back the out from the square as there were pointing into it. they didn't know if they'd have to fight part of their own Army when word got out what was going on inside he square.
