(These are MDMP steps 2, 3, and 4. See chapter 9 for a detailed discussion of the MDMP.) The G-5 (S-5)-developed COAs provide the basis for military deception COAs. The military deception officer develops military deception COAs in conjunction with the G-5 (S-5). Basing the military deception COAs on the operational COAs ensures deception COAs are feasible, practical, and nested and effectively support the operational COAs.
