Yes, stock AT weapons would be nice it would compliment the infantry vs tank part without the olympic hammer satchel toss:
Here's my wish list:
German:
Pak 36 (37mm PaK 36 L / 46.5): HEAT ammuntion verison also needed!!! HEAT was common in '42 to keep this weapon useful. The HEAT round could defeat any tank of the time (180mm of penetration) however it lacked range and accuracy with this round. HEAT round Pak36 pictured here:
Pak 38 (50mm KwK 38 L/60)
Captured 76.2 (F-22 most noteably) Soviet guns using German banded Pzgr. 39 ammo (which gave it superior penetration than the original round)
Pak 40 (75mm Kwk 40 L/48)
Flak 36 (88mm L/56)
Maybe some large caliber arty gun like:
150mm K 18 L / 55
Soviet:
45mm Model 1937 L/46-proper penetrion table is must for this one it is more or less this is the Soviet "door knocker".
76 M1936 or M38 (F-22)
76 mm M1942 ZiS-3
85mm Model 1939 L / 52 (penetration is almost identical to the T-34/85..and somewhat less than the Pak 40)
122 mm gun M1931/37 (A-19)
