Factors of foot marches for typical dismounted units ATP 2-01.3 Basic data table, foot marches Terrain Visibility Rate of march* (km/hr) Normal march (8 hours) (km) Forced march (12 hours)(km) Roads Day 4 32 48 Night 3 24 36 Cross-country Day 2 16 24 Night 1 8 12 *Computed on a 50-minute hour, allowing for a 10-minute halt each hour. Length of column*, factor table, foot marches Formation** 2 meters person distance 5 meter/person distance Single file 2.4 5.4 Column of twos 1.2 2.7 *To determine the length of a column occupied by a dismounted unit, multiply the estimated or known number of personnel by the applicable factor. **Foot marches vary with the tactical situation; normal formation is a column of twos with a file on either side of the road and staggered, much like U.S. forces. However, columns of threes and fours may be employed where conditions permit. Pass time factors*, foot marches Rate (km/hr) Factor 4 0.015 3 0.018 2 0.020 1 0.023 *To determine the pass time in minutes for a dismounted unit, multiply the length of the column by the appropriate factor for the estimated or known rate of march.
