2 cm KwK 38 Penetration Tables

By 1941, the PzII wasn't exactly a top of the line tank, and its firepower left much to be desired. These instructions reveal how to squeeze the most out of a gun that hasn't aged well. 

The tank has three types of ammunition:
  • Pz: armour piercing
  • HK: "hard core" subcaliber armour piercing (not to be used at a range of over 250 meters)
  • Sp: high explosive
The tank silhouettes are labelled as follows:
  • Solid black: destructive effect
  • Shaded black: hindering effect
  • White: no effect
Otherwise, the advice is largely the same as in the Pak 40 instructions.

Against the Valentine, there isn't much the 2 cm KwK 38 can do. Firing at the gun mantlet, machinegun port, and driver's slit is bound to have some effect, but the only guaranteed damage is APCR straight to the back of the turret. Firing HE at the engine deck might start an engine fire. Interestingly enough, the tracks aren't indicated as a weak point. Presumably 20 mm HE shells are not powerful enough to break them.

Against the Churchill, the idea is the same: hammer away at anything there shrapnel can make it through to jam mechanisms or injure the crew. You can try shooting underneath the tracks from the side or rear at close range, when the tank is at a strict right angle from you.

Against the M3 Lee, you have a few more offensive options. From the front, the area around the main gun is vulnerable to subcaliber ammunition, as is much of the side and rear. The Sherman, while invulnerable from the front, can also be penetrated at close range from the side and rear. At least, in theory, the notes below clarify that these are just calculations.

The T-34 (for some reason the three-periscope driver's hatch and two-periscope driver's hatch versions are separated) are much less vulnerable than the Sherman: you can only penetrate them by shooting at the lower hull, behind the wheels. KV tanks are completely invulnerable (barring engine fires from getting HE through the grille), as is the Matilda, which mysteriously migrated to the Soviet page instead of the British one.
