What is the title for the individual in charge of a company?

The title of the individual in charge of a company within the context of fire service terminology is "Company officer." This role typically includes responsibilities such as supervising firefighters, ensuring operational readiness, managing incidents, and overseeing training and development within their assigned company. The company officer is key in bridging the gap between the crew and higher command, effectively managing both personnel and resources during emergencies.

The other titles presented do not carry the same specific responsibility for leading an individual fire company. For example, a squad leader might oversee a specific subgroup of firefighters but does not encapsulate the broader leadership role of a company officer. A resource director usually focuses on managing resources across multiple units or functions, while a sector manager would typically manage a specific sector at an incident scene and would not be in charge of a whole company. Hence, "Company officer" is the most appropriate and recognized title for an individual in charge of a company within this context.
