WP both. So aggressive PE (two times more than he should be) and so relentless defenses' building US player. Yeah, mortars came late and the doctrine wasn't good choice, but CoH is played by people not machines (fortunately) :-). Indeed – nice to watch.
what i can say is the PE retreated way too much, even when he could have taken on the riflemen. The mining was a great idea but again, if the PE player knew his stuff, he'd tell his units to Attack Move instead of just right clicking and the PGs would have simply sidestepped the mines. Otherwise, good play from the Ami player. You can tell he knows his stuff cuz he'd blob back, which is actually what you should do against PE. Meet 3 squads of PEs? Three bar riflemen, POW!!! And obviously a 30.cal is great for backup.
I noticed theOne didn't have almost any command points even halfway into the game. Makes you wonder wth was happening.
