Lower Plate Critical Hit ?

Draschel: What ammunition where you using? HE or HESH?If so, striking the LFP can splash the tracks with HE effect. The shot itself may deal no damage as in too weak, say when you attack something thick like Maus or 268V4 with tiny caliber HE, but radius maybe enough to damage track module. But if you were using HEAT, AP, APCR. I am sure this is what happened::https://ibb.co/GkTf083 It may appear you shot LFP, as many cases they are the same appearance. But you instead shot spaced armour struts that envelope the axles and road wheels. You penetrate the spaced armour easy, usually 30-50mm, but then fail to pen the tank body afterwards. The critical hit** is for penetrating the spaced armor.
