How should a COTAC conduct rehearsals and pre-mission drills, and what should they address?

• A. Rehearsals cover weather forecasting and safety drills.
• B. Rehearsals focus only on equipment checks.
• C. Rehearsals cover only administrative procedures.
• D. Rehearsals cover key tasks, triggers, callouts, contingencies, ROE, and deconfliction.

Answer: (D)

Rehearsals and pre-mission drills should simulate the full mission flow and build a shared, actionable understanding of what must happen, when, and how. The emphasis is on the key tasks—the critical actions the team must perform in sequence. They train the triggers that start those actions, so responses happen promptly and predictably rather than on impulse. Standardized callouts are practiced to keep communications clear and unambiguous under pressure. Contingencies are rehearsed so the team can adapt to failures or degraded conditions without losing coordination. Rules of engagement are drilled to ensure every action stays within policy and mission constraints, and deconfliction is practiced to prevent conflicts with other assets, airspace, or friendly forces. Taken together, these elements ensure the drill validates execution, timing, communication, and decision-making, while revealing gaps in plans or procedures before a real operation. Weather, safety, and administrative points matter, but they should be embedded as decision points within the drill rather than treated as standalone topics.
