Yeah but why can a medium tank can take 5 hits when the more expensive P4J only takes 4 hits? That does not make any sense.
The Auf J has 234 armour and typically faces at far range:
- AT guns with 190 pen or less
- PTRS (A meme vs this unit)
- PIATs (A meme vs this unit with 110 pen)
- Zookas (Also a meme vs this unit, except maybe for Rangerssssss)
- Med tanks (80-120 pen typically). There are higher ones (Eg: Ez 8's 155) but they're doctrinal and not often used.
- TDs with 210 pen or more but are a huge threat to them due to speed and model size
That's a lot of bounces from most of that list, esp from contemporary med tanks. Yes the infantry AT has high deflection damage but an auf J will roll right over you (figuratively) long before your deflection dmg kills it. TDs and AT guns are still penetrating reliably but even then it's not a guarantee in the case of the latter.
Has the auf J cost me games? Absolutely, when its armour fails to a t-34/76 but I've lost count of the no. of times Comets and TDs/AT guns bounce repeatedly.
