  3-125. The level of planning and preparation time required for an air assault is driven by the operational
  and mission variables, as well as the training level and habitual relationship of the AATF. Although air
  assault operations can be complex, maintaining continuous friendly and enemy running estimates, using
  common SOPs, maintaining continuous liaison and habitual training relationships and continuous target
  development through reconnaissance and IPB all increase the agility of the AATF to seize the initiative
