Who us, detour? We're just waiting around for new tips!
I heard of a case in the first gulf war where an M1 got pointblanked by a t72, they had run into an area where bunkered T72s had been left off for days to get their heat signature down, had marked all but one based on spotting Tank commanders using NV goggs. The round did penetrate the m1 and blow the ammo, all 4 crewmen were evacuated to other vehicles under their own steam. That'd be the bellringer to end all bellringers! The T72 never had time to get another in the pipe.
