As for the discussion on why the predator in this one fumbled the use of its gear:
It seems to me that he understands how it works, but is using it recklessly moment to moment. When he is using the homing bolts weapon against the brother and they are hitting the tree, its all close range and he doesn't care if it redirects after launching, he just needs the brother to be in the initial path. When the bolt redirects and ultimately kills him at the end of the last fight, he is unaware that the helmet is there and pointed at the back of his head.

move all remaining groundhog mercenaries to the front lines. Have sheep troopers squadrons A and B flank the cows. They're using DC-17 hoof blasters.
