Reading The Field

I ran the PT vs YA test 3 times in custom battle on normal difficulty. I took the PT as defender and set them in 2 ranks, hold formation with fire at will turned off. The AI had a YA general's unit (which gets +2 morale), and it ran the YA in close formation toward my PT to attack. When the YA was 40 meters away, I switch on fire at will which made the PT unit fire it's full 60 man volley when the YA was approximately 30 meters away. In the 3 tests I got, 10 kills, 11 kills and 9 kills respectively with the single volley. The YA routed in all 3 tests.
