With mortars, bots fire them continually if an enemy is less than 10 meters away while they are mounting the piece, but they aim far off in the distance, this is especially noticeable in El Al, at Kidney ridge
What I don't get, however, is howitzers. Bots on a map like Gazala, can fire their tank cannons a good kilometer, but don't seem to care for howizers at all
A warning regarding artillery however is, once its fixed, we need to introduce some sort of check to prevent it becoming a rape-fest - For example, perhaps have bots like arty only partially so that they harass targets within range or LOS and then bet off the gun once there are none in sight so that arty can be used only at times...
Bots used to like the lafette Mg42 about 50-50 in 2.2, now however, they don't seem to see either the bipod or the tripod of this gun. They do use the mg34, although I've seen this occur i.e the lafette, only once in PHL. However, the bots consider it a must when they are close to the Mg15 and they stay on this gun indefinitely.
The worst part of dealing with bots is that there are so many schools of thoughts as to what bots should and shoudln't do, so when one person changes AI to do one thing right, they tend to make bots do something else completely wrong
Inspite of all its shortcomings, however, I must say the 2.25 bots show signs that they underwent the most ambitious modifications... For instance, if you get the rare occasion where an AT-rifleman decides to lie prone to use his AT rifle, he remains there indefinitely firing flat - A sign that the devs tried to make bots use this position exclusively, or at eleast alot more than standing.
Also, bots who get startled by a tank or an enemy infantryman, run a good pace before stopping to fight or change direction, moreso than in 2.15 and 2.2, where fleeing was first introduced
