Order of War focuses primarily on the Summer of 1944 as the second World Ward entered its end-game. The Allies launched two major operations that would drive back German forces on both the Western and Eastern Fronts at once.
Their names were Overlord and Bagration.

Overlord famously commenced with the D-Day landings in Normandy and ended in the Liberation of Paris, while Bagration - a far less well-known but far larger Russian operation - crushed the invading German forces in the east, leading to their complete withdrawal from Soviet territory. The game features key historic battles and missions from both operations offering 2 very different campaign modes.
