CHAPTER 1 INTRODUCTION irLand Battle doctrine has produced great changes in the Army. It Ahas affected everything from equipment to the way we fight. Commanders need to understand these concepts and how they affect the employment of an infantry battalion. This chapter introduces AirLand Battle doctrine and explains its effect on battalion-level tactical doctrine. Section I THE ROLE OF THE INFANTRY BATTALION The infantry battalion serves many roles on the airland battlefield. It engages most often in close battles and may conduct raids or stay-behind operations as part of deep operations. The battalion may participate in rear battle as part of a tactical combat force. Also, due to their rapid deployability by air, infantry units are ideally suited for executing strategic contingency plans and establishing lodgements. Limited visibility is the basis for infantry battalion operations. It is the environmental condition that the US military seeks to take advantage of its technology and training. Darkness, fog, heavy rain, and falling snow all limit visibility. A combination of technical ability (afforded by NVDs) and tactical prowess (afforded by training) allows the infantry battalion to operate routinely during these conditions. Limited visibility operations strike the defender when the range of his weapons and the mutual support between his positions are reduced. 1-1. THE AIRLAND BATTLE maneuver at all levels and tries to use the full Infantry forces can operate effectively in potential of US forces. It is offensively oriented low-intensity, mid-intensity, or high-intensity so commanders may go to the offense as soon as conflict and in most terrain and weather possible.
