Also, the march should be completed by daybreak with troops in concealed positions. When movement is near the enemy, noise suppression must be considered. To conceal operations from the enemy and to prevent him from gaining information about the march, measures to maintain security must be enforced. The use of navigational aids, such as ground surveillance radar, thermal sights, and night vision devices, can prevent many command and control problems encountered during night movements. This includes reconnoitering of routes and assembly areas.
Special precautions ensure direction and contact within the column.
Therefore, guides and file formations are needed. Forced marches require speed, exertion, and more hours marched. They are normally accomplished by increasing the marching hours for each day rather than the rate of march. Forced marches are employed only when needed since they decrease the effect of units. Troops should be told the reason for a forced march to ensure maximum effort.
