Indian warriors in the West, using their traditional style of limited, battle-oriented warfare, confronted the U.S. Army. The Indians emphasized bravery in combat while the Army put its emphasis not so much on individual combat as on building networks of forts, developing a logistics system, and using the telegraph and railroads to coordinate and concentrate its forces. Plains Indian intertribal warfare bore no resemblance to the "modern" warfare practiced by the Americans along European lines, using its vast advantages in population and resources. Many tribes avoided warfare and others supported the U.S. Army. The tribes hostile to the government continued to pursue their traditional brand of fighting and, therefore, were unable to have any permanent success against the Army.
