A couple times while I was playing the campaign I would run into an enemy cargo truck sitting in the middle of their base. Normally its mere existence wouldn't be a problem but my AI friendlies would point weapons at the truck, ignoring hostiles that are sometimes closer. This is extremely frustrating when I'm in a tank and my gunners point at the truck instead of enemy guys trying to blow us up.

I want it so that that truck is at the bottom of target priority and my allies would kill everything else in sight first before turning their attention to the truck.
