When the United States entered the Great War, John J Pershing was chasing Mexican bandits and the US Army was a constabulary of frontier cavalrymen.

In a year Pershing transformed that constabulary into a modern army ready to strike the decisive blow against the Kaiser's war machine.

Through force of will and with the backing of Washington Pershing built an army in his image, counting on 'open warfare' tactics to win where the British and French has lost.
