What are the 3 organizational elements?

• A. March/Convoy Commander, Serial/Serial Commander, March Unit/March Unit Commander
• B. Head, Main Body, Trail
• C. UMO, UMC, DMC
• D. Lead Vehicle, Support Vehicle, Tail Vehicle

Answer: (A)

In a march or convoy, authority is arranged in three levels: the person in charge of the overall march or convoy, the commander who leads a block of vehicles in sequence, and the commander who leads the individual marching unit within that block. The March/Convoy Commander sets the plan, timing, route, and safety standards, and keeps coordination with higher and adjacent elements. The Serial Commander handles execution for a subset of the convoy, maintaining proper spacing, communication, and adherence to the plan within their serial. The March Unit Commander leads the individual unit, directing actions, maintaining prescribed spacing, readiness, and responsiveness to signals and orders. This structure ensures clear accountability and smooth coordination from the overall plan down to each vehicle or unit. The other options describe convoy parts or unrelated labels, but they do not reflect the formal three-level command arrangement used to organize a march or convoy, which is why this choice fits best.
