seeing if they didn't use all thier units at once is simple enough. just 'count' which units are in their location and which aren't. if they're moving them individually and only one hasn't moved, you could just conclude that they player hit it's location, even if they didn't. if more than one hasn't moved, then you can just stop the calculations. the female dog is detecting when they all moved individually.
