A twin tandem 180 mm thermal-enhanced warhead with Du cones could easily penetrate 1 500 mm RHA. >AFAIK, there were a couple of M1A2-equipped battalions in Desert Storm. No, M1A1 (HA), with (HA) standing for (Heavy Armor). The US Army is supposed to have 77 M1A2s now. >Don't doubt that one - DU rounds were designed to rip through Chobham >armour like it wasn't there.

Du rounds were designed to deal with the T-72 after 105 mm M392A1 APDS bounced off the frontal armor of Syrian T-62's about 40% of the time in 1973. >Story time (it's been posted before, but I'll post again for the benefit of >those who missed it): During Desert Storm, a M1 managed to get bogged in a >mud hole.
