The Top row “Relick” ERA (especially the 4 ERA plates near the driver optics) on T-80BVM’s front armor not work properly, it can pen by DM53 or slppprj m/95 or M829A2 over 400m in some cases while playing gournd RB, which will definitely not happen in the protection analysis, please check and fix it.
its called relikt, also ERA does work properly just that some shells have enough brute force to go through
Don’t rely on protection analysis.
It’s better for a general guess, but not to be taken as a hard fact.
