Battalion chief
A battalion chief is the rank and title of a subordinate fire chief or commanding officer in the firefighting command structure. The title of battalion chief is usually synonymous with firefighting in the United States and Canada.
A battalion chief is the lowest chief officer in a fire department's rank structure, above rank-and-file fire station and fire company officers. A battalion chief commands a firefighting battalion, similar to a military battalion. A battalion consists of several fire stations and multiple fire companies. A battalion chief has command over each fire station's officers and each company or unit's officers, as well as the uniformed firefighters.
