If you take control of a man as Zeus with the remote control module then release controls, the AI will not properly aim at enemies and never or barely ever will fire his handheld weapons at an enemy again on foot or riding in a ffv position. The only way to fix it is to delete and replace him.
This does not seem to affect their abilities if they are manning a weapon that's static or gunner of a vehicle,but they will be broken whenever they are ever on foot before or after they manned it if they were ever remote controlled.
