Army Structure, Ranks, and Chain of Command
Army Structure, Ranks, and Chain of Command tests how units fit together, how rank and authority work, and how a soldier seeks guidance or resolves problems through the chain of command and the NCO support channel.
Core rules
- A fire team is a small element of about four soldiers; a squad is roughly 9 to 10 soldiers; a platoon is typically 16 to 44; a company is roughly 60 to 200; a battalion is about 300 to 1,000; a brigade is roughly 1,500 to 3,000; a division is about 10,000 to 15,000; a corps is larger still.
- Enlisted ranks run E-1 through E-9. Warrant officers run W-1 through W-5. Commissioned officers run O-1 through O-10.
- The chain of command runs from team leader through squad leader, platoon sergeant, platoon leader, first sergeant, commander, and higher. It carries lawful authority and responsibility.
- The NCO support channel runs parallel and advises commanders; it does not replace the chain of command. First sergeants and sergeants major are key nodes.
Worked example
A soldier has a pay problem. The soldier first raises it with the squad leader, who helps route it to the platoon sergeant and first sergeant, and then to the commander or administrative section as needed. Reasoning: the issue is administrative, so the chain of command coordinates the fix; the NCO support channel helps enforce standards and advise, but the commander retains command authority.
Traps that cost marks
Treating the NCO support channel as a separate command chain; skipping levels without a legitimate reason; confusing specialist and corporal authority; and misreading rank insignia. Also avoid assuming every problem goes straight to the commander; routine issues normally start at the lowest appropriate level.
