Ground forces in Central Europe consist of varying combinations of firepower and maneuver units. Maneuver forces include tanks, infantry, and highly mobile reconnaissance or screening units. Battles are usually fought not between tank units or tanks versus anti-tank weapons but between combined arms forces of tanks, infantry, artillery, and sometimes tactical air forces. Battles consist either of combined arms assaults on prepared def ensive positions or of meeting engagements between two mobile forces. In a meeting engagement, maneuver forces on both sides move directly from march to assault without stopping to assemble and jump off again. 1
