So I was messing around in the editor, and I'd put a squad of enemies to the front, so I could see how the new firefight mechanics worked. [did this just when I booted up, before I tested infantry combat. Fantastic, by the way.]
So, I move forward to attack the opfor soldiers [4 divers and 2 riflemen in one squad] and I take down two of the divers from afar, one up close, and the riflemen with a rifle grenade. The last diver comes charging out of cover and runs directly in front of me, doesn't shoot at me, and runs away towards the lake [note, this was in Agia Marina]. I was confused, and waited a couple of minutes, and he stood in front of a rock, looking at the rock, and did nothing, for a solid couple of minutes, before I put him out of his misery.
