The difference here is that the 1 shot kill MAY happen to Abrams and WILL NOT happen for the chally. If you fire at the Abrams in cover, it may die at any moment, but you have to wear the Chally down. That is a big difference.cordas said:Now if you take those 10 shots at an Abrams cover (1 of which will kill) and fire those same 10 shots at a Challie in cover the Challie will be just as dead from failed armour saves.... Ok its not going to be one shot killed, but those 1 shot kills either happen all the time or never.
As for better anti-infantry capabilities and speed: one inch speed difference is not that much, the Challenger may open an extra fire zone as well (with the GMPG) , so the only difference is one MG less (and GMPM instead of .50 cal) - not that much...
