At its annual show in October, the U.S. Army's vision of the future was front and center. All echelons, at least in combat, are to share a common tactical picture (lower echelons will see their parts in greater detail). That will make it possible to share quick tactical decisions up and down the line. Since the tactical pictures will be in everyone's computer, changes can be implemented automatically. For example, logistic support can be adjusted automatically to match changing plans. The common picture also should create much better situational awareness, including better identification-friend-or-foe. Using the common picture, an artillery battery can attack enemy positions without risking hits on friendly ones. The concept is sometimes called the digitized battlefield. The U.S. Marine Corps is buying much the same system.
