"But it is just a fact that when a T-72 or any other Iraqi tank was hit by a DU round from a 120mm gun there were no survivors."

All that I can say based upon game experience is that when iraqi T-72s meet abrams they tend to die rather quickly, as they should.Not everyone plays exclusively GW1 scenarios,do you really want to make the T-72s weaker than they should in others scenarios against others threats to have less crew survivors running around in 1991?
You cannot simulate accurately everything here,consider the lack of tandem HEAT warheads for guns and RPGs for example.
