Thanks for the replies

While I do agree requiring infantry to protect your tanks is a neccessity in terms of tactics. It's not always fun to have "kamikazi" rushers with AT nades take out your tanks before your infantry react and kill them all.
To that extent, myself and my buddy found out how to "Decrease" the severity of AT nades to the point where they now "disable", but not kill, certain well armor medium tanks....destroy light tanks and armored cars out right, and only disable heavy tanks if it's a square hit on the engine.
For others looking for the same solution that we came to. You must edit the hitpoints.reg file and change ap nades to 0.5, and THEN you go into the set/stuff/grenades folder and modify the 3 AP grenade's energy to 3, 4, 5 (mp40, mp43 etc) in terms of their severity as Russian grenades (mp40) were always the weakest.
