Vehicle Damage made armors very hard to be destroyed

[acknowledge14]

Hi, I notice in singleplayer mode, the armor vehicles are too hard to destroy(most of the time), even with direct hits from multiple powerful rounds. This makes some missions unable to proceed(some tasks can only be completed with certain armors been total destroyed).
I use zeus enhance mod to check, and found out those armor vehicles' hull component damange to be 89%(max).
Is there something I can do?
