3-66. ADA planners review the initial DAL to ensure that sufficient resources are available and allocated to provide adequate protection. ADA planners review and revise the list continuously throughout an operation, in accordance with changes in missions, threat capabilities, available ADA forces, and related factors. For instance, when a mission changes, subordinate commanders and their staffs may nominate additional assets for inclusion into a re-prioritized list. The updated DAL then becomes the basis for revised AMD planning and defense design.
