I've also noted that German riflemen fire standard rifle grenades at T34. The damage is insignificant and focuses them away from infantry threats. This might not be a good threat assessment for them.
Again, not my buisiness - the general behaviour like this should be reported in the 2.5 Singleplayer thread, this has nothing to do with my work in particular.
I thought you set the AI template for Russian tanks because they are clearly reacting to them as they would light armor, not medium armor. Or did Russian tanks already have that set?
Sorry if I'm mistaken.
The rifle grenades in the default German rifleman kit on Arad, Dukla and Seelow - they are not frag grenades, they are HEAT. The same HEAT grenades you can find in, say, the AT kit on Operation Cobra. On Cobra they are mildly effective against Shermans, but, as it seems, they are very weak against the Russian armor.
On planes bombs: I did tweak the bombs for FH 2.5 to be less accurate, but apparently it did not help much. Will try to tweak them more.
On HE shells: did I make them too accurate, especially in static guns, or it's just you, guys, being not accustomed to AI utilizing them against infantry?

Darman, what handhelds do you mean by "firing their handhelds at ineffective range"?
I very often observe how bots start discharging everthing at their disposal right on spawning, even when the enemy is still far out in the fog or behind terrain obstacles. Firing from the hip, mostly.
This is weird because the maximum range for weapons capable of automatic hip fire is set to 100m or so, far below the fog range on almost all maps.
