Infantry, WW1

WW1 INFANTRY -  The First World War precipitated a revolution in infantry tactics that changed the course of warfare.  Armies adapted to modern industrialized war along a four-year learning curve, moving from 19th century linear formations to trench warfare and ultimately to mobile combined arms.

The United States Army and Marine Corps began arriving in France in 1917 following the nation's declaration of war against Germany in April of the same year.  The army formed the largest body of troops and consisted of three different organizations: eight Regular Army divisions, seventeen National Guard divisions and eighteen National Army divisions, formed by men drafted for national service. 

By the end of the war the American Army suffered 52, 947 killed and 202, 628 wounded.
