FCX stands for?

• A. Field Communications Exercise
• B. Fire Control Exercise
• C. Fire Coordination Exercise
• D. Command Post Exercise

Answer: (C)

Understanding what FCX stands for in US Army training helps you see the purpose behind this kind of drill. FCX stands for Fire Coordination Exercise—a scenario designed to practice planning, synchronizing, and deconflicting fire support from multiple assets across units to support the maneuver. The focus is on coordinating fires so they work together smoothly, hit the right targets at the right times, and avoid fratricide or collateral damage, all while staying aligned with the commander's intent. This goes beyond simply the mechanics of firing (which would be a Fire Control Exercise), or the technicalities of keeping communications up (Field Communications Exercise), or broad command-post decision making (Command Post Exercise).
