Army Corps, Regulations, and Military Protocols Practice Test

Understanding who leads a battalion comes down to rank and unit size. A battalion, typically 300–1,000 soldiers, is commanded by a Lieutenant Colonel. That rank matches the level of responsibility for directing multiple companies and guiding battalion-wide operations. In the provided options, the person with that rank is the Lieutenant Colonel, which is why this individual would be the battalion commander. A Captain normally commands a company, the building block within the battalion, so a captain wouldn’t command the entire battalion. A Colonel would usually command a brigade or higher echelon, not a battalion. The Command Sergeant Major is the senior enlisted adviser to the battalion commander and does not hold battalion command. So the battalion command duty aligns with the Lieutenant Colonel, hence LTC Mopp.
