Which unit contains multiple battalions and is usually commanded by a colonel?

• A. Brigade
• B. Battalion/squadron
• C. Company/battery
• D. Regiment/Group

Answer: (D)

A regiment (or group in some forces) is the formation that brings together several battalions and is typically commanded by a colonel. In infantry organization, a battalion is led by a lieutenant colonel, and when multiple of these battalions team up under one command structure, the result is a regiment. This arrangement allows for coordinated administration, training, and operational planning across all battalions within the regiment. The term group is used in some military traditions to describe a similar size and role, but the common thread is that this level of organization sits above a single battalion and is led by a colonel.
