Both the M1A2 and Challenger 2 have successfully defeated dozens of RPG-7 rounds per tank.

dont forget the TUSK ERA scales that can be fitted on a M1A in addtion to the DU enforced 1st generation chobham the challenger got the longest range t2t kill at 5.1 km the M1A1 has engaged upto 4km. but chally only got the 5.1 km opportunity becasue the terrain was flat and conditions right. Rifled guns are more accurate and the longer barrel gives it more velocity but smoothbores are more detructive outright. Britaina nd india re the only 1's that still use rifled. Although smoothbores are less acuurates the M1A2 targeting makes up for it. The M1A has a C4ISR interface all combat data can be quickly relayed to other M1A2's,Strkers,Apaches,Super Cobras,F 18 E/F's, A10 's bomber etc and command &control. This allows the M1A2's to coordiante a lot more firepower than the challenger. STAFF although cancelled can give M1A2 extended range beyond conventional munitions to amek up for the Chally's slighly longer range.ANd a british capatain said the armor protection levels are similar(but thats without TUSK)> equal in most respects but theC4ISR gives the M1A2 an advantage.(calling in superhornets to launch mavericks at challys ays quite alot.
