Sniper Rifles make the Enemy Infantry act all shy

Has anyone else noticed that the AI hesitates on the border of your sniper's range in this game?

On defense missions; enemy infantry can be stalled out be just putting a Squad with sniper in a high point and they spend the entire time scurrying around the endge of you range until the timer runs out.

Chalking this one up to the game being in early access and I'm still in the earlier parts of the game atm.
