Exactly what I was thinking. Are there any instances of the Crew Compartment of a buttoned-up US-Spec M1A2 being penetrated? I know one got “knocked out” when an RPG-7 firing a tandem-warhead round severed a fuel line in the engine compartment, but I know of no instances where the crew compartment was fully penetrated.

The Saudi M1A2S only have their electronics upgraded to the SEP standard, they have the armor of an A1 (no DU)
