ERA Blocks on Tanks?

So been noticing that tanks with ERA Blocks seem to keep that protection after hitting the area, am I mistaken shouldn’t those areas no longer have any addition armor values so the round should penetrate the location with the next round.

But doesn’t seem to be working that way in game I’ve smacked T-80 in the same spot 5 times and the round is L27A1 so shouldn’t be a issue pinning the tank but its like the ERA blocks are still effecting the armor values because the round just melts away and no damage.

So could it be possible that they are not working the way they should be?

My guess is one of the issues with the game’s computing. This also happens with HEAT rounds where even if you hit and detonate a portion of ERA on a specific spot, shoot it again, the probability of the HEAT being detonated and ineffectively penetrating is high. As if the ERA wasn’t exploded.

L27A1 just sucks. If it is T80B, might just be tough luck, happened to me also with even stronger rounds like DTC10125, if it is T80U, well, not much I can say.
