AIR MOVEMENT TIMINGA successful air

AIR MOVEMENT TIMINGA successful air assault operation is a sequence of actions carefully planned and precisely executed.The basis for timing is the time when the first aircraft in the first lift of the operation touches down on the LZ. It is referred to as H-hour. In FM 3-99 H-hour is defined as, “The specific hour on D-day at which a particular operation commences.” All times in air assault operations are referenced from the H-hour (landing column, air movement table). The H-hour in an air assault operation is equivalent to the attack time in an OPORD. If delays are encountered due to weather or aircraft delays, the commander announces a new H-hour.
