What do the red, targets mean?

I apologize if this is in the wrong category and I apologize if the game provides an answer I've overlooked**
I've been curious about the circles surrounding the enemies. Some are dotted and some slightly look like a gear. What do they mean? Does it determine how many steps they take a turn? How hard they hit? Ect. I feel like knowing will improve my plays dramatically.

You have:
Unaware : no circle. --> Walker stays in position untill they notice you
Wandering: circle with interupted line. --> Walker walks about until he notice you
Aggressive: Circle with un-interupted line. --> Walker will actively move the fastest route to your survivor
