This occurs sporadically but regularly enough to warrant reporting as an issue, not present in my A2 experience.
Soldiers were ordered by AI squad leader to engage single targets at 700+ m distance, after a while the units responded "cannot comply" and returned to the group but progress to the actual objective is delayed.
This doesn't seem particularly realistic behaviour and causes a loss of focus on the objective (and squad cohesion) in response to an enemy spotted which is not a serious threat. (single man at 700m)
On soft contact decision would be made to attack, defend or bypass/withdraw and leader AI's default (only?) decision seems to be attack all the things.
Didn't notice a problem in A2, but as it seems no consideration given to threat and distance, now in A3 (due to improved spotting distances?) defaulting to engage makes for some daft orders to subordinates.
Of course, AI must deal with any immediate threats before proceeding to waypoints but squads seem too easily distracted now and this behaviour is making mission design more difficult.
I would request a simple check for distance (and perhaps if the spotted enemy knows about AI's group) before ordering any element to engage.
