After watching this replay I can confirm maphack is being used.
No need to write the timelines here as usual, its to obvious.
At the start the Wehrmacht sets up his MG at the fuel point in the left bottom corner, while the britt is capping the ammo point. He sees the MG trough the Fog of War and moves his unit a tiny bit so the MG can't hit it.
Later on he exacly knows how to move to kill chase the wehrmachts sniper, which didnt even shoot a single shot.
Then he gets a stuart, sees the AT in the FoW .. so keeps his stuart safely behind the hedge.
Conclusion: Maphack Confirmed
some chinese / asian player....
