The Five Steps of Reverse Planning are abbreviated as GLALS. Which option lists these steps in the correct order?

• A. Ground Tactical Plan; Landing Plan; Air Movement Plan; Loading Plan; Staging Plan
• B. Ground Operations Plan; Landing Zone Plan; Air Mission Plan; Loading Plan; Sequencing Plan
• C. Ground Reconnaissance Plan; Landing Plan; Airspace Plan; Loading Plan; Staging Plan
• D. Ground Movement Plan; Landing Plan; Aero Movement Plan; Loading Plan; Staging Plan

Answer: (A)

GLALS represents a reverse-planning sequence: Ground Tactical Plan, Landing Plan, Air Movement Plan, Loading Plan, Staging Plan. This order builds from how forces will operate on the ground, to where and how they will land, to how airlift will bring them to that location, to how cargo will be loaded for transport, and finally to how units will be staged for execution once they arrive. The option that lists these exact steps in this exact order is the best fit because it preserves both the terminology and the progression implied by GLALS. The other options mix in different terms (such as Ground Operations Plan, Landing Zone Plan, or Air Mission Plan) or rearrange the sequence, which breaks the established GLALS order.
