In some situations (when behind the vehicle and on a rooftop, for example) the AI won't fire their Titan launcher or PCML if the target is a wheeled vehicle. See steps to reproduce and see it for yourself.
The AI is able to engage if there are multiple units in the group.
Even if the AI can engage it takes a long time for him to do so. On level terrain it takes 15 seconds for him to prep the launcher. {F22307}
Currently the AI behaviour is unacceptable and can cause huge issues either in single player on in coop missions. Fixing such AI issues should be a high priority.
Armed with PMCL or Titan the AI wouldn't attack the Gorgon or Madrid. OPFOR with Titan wouldn't attack the Marshall, but with RPG would attack the Marshall. OPFOR Titan vs other armorded units did attack.
Maybe an issue with using AT vs the light APCs? Seems it's vs wheeled vehicles.
The problem is that AI does not want to engage targets until discovered by enemy.
Only typing "veh reveal this" into units init (veh = target) makes AI start engaging the target - choose proper weapons, etc.
Desired effect is - after some time AI should engage target and return to hidden position.
A SINGLE AI-AT soldier doesn't attack Marid/Gorgon/Marshall on his OWN if not being attacked or discovered.
2 or more AI's in the group, and AT WILL attack them even if not discovered.
The issue is only with single unit "groups".
@AzzurF
Can't repro. I added 1 AT specialist to the same groud and they were unable to engage the vehicle.
Placed a dozen or so AT specialist to one group and put them on the runway. Placed AFV in front of them and not even one wanted to do something else than just lying on the ground, aiming the vehicle with their rifle.
I'd say it's quite a flaw if NATO/AAF don't have even one single AT weapon that can be used in such situations against wheeled vehicles. RPG-42 is the only weapon in the game that the AI can use.
I can't repro That. My guys engaged EVERY time. You should do a repro mission of that situation too.
I tried AFV's, Marids, differend locations, 1-12 AI's and every time they destroyed it.
And yes, I noticed that the alone AI-AT does engage too. He just waits a bit longer, when the target is APC.
So, being "alone" is not an issue, not using launcher at APC's is not an issue.
But the rooftop placement May be an issue:
In some cases, if the AI goes prone, he loses the line of sight to the vehicle. When alone, he is not ordered to engage target that, when grouped, someone in the group would see.
If you move the AT guy on top of the "Barracks (New)" building near the one in the repro and near the edge, give him 8 meters elevation, facing south, move the AFV south facing away from the AI, so the situation is like in the repro - but now he sees the AFV when prone: wait few seconds and the AFV goes boom.
Disregard my last post, it seems I didn't wait long enough. It just takes a lot more time. If a unit is alone, it takes 15 seconds until he preps his AT weapon.
Edit:
Prone stance is not an issue. The AI won't shoot in the repro mission even if you put 'this setUnitPos "MIDDLE"' to its init field.
Afaict this has got fixed by the target and ammo selection improvements over past months.
Thank you you for your help here!
