E-70. Infantry units may be attached to armored units during combat operations. Table E-4 shows a list of tasks Infantry units may perform while attached or under the operational control of combat vehicular units.

E-71. Leaders of combat vehicle units often fail to recognize the speed with which the Infantry can move when operating dismounted. Numerous factors can affect the rate of march the Infantry forces including, tactical considerations, weather, terrain, march discipline, acclimatization, availability of water and rations, morale, and individual loads. Table E-5 summarizes dismounted rates of march for normal terrain. The normal distance covered by an Infantry force in a 24-hour period is from 20 to 32 kilometers, marching from five to eight hours at a rate of 4 kilometers per hour (kph). A march in excess of 32 kilometers in 24 hours is considered a forced march. Forced marches increase the number of hours marched, not the rate of march. Absolute maximum distances for dismounted marches are 56 kilometers in 24 hours, 96 kilometers in 48 hours, or 128 kilometers in 72 hours.
