It is June 1941. The Third Reich embarks upon the greatest military campaign of all time. The Wehrmacht attacks across an 1800 mile front, with 3.8 million men, 3350 tanks, 3000 aircraft, and 23,000 artillery pieces.

Now, as a small-unit commander in the most significant campaign of the 20th century, it is up to you to win your battles, and shape the world, before it's too late.
