Interested in a career in firefighting but want to see what the career trajectory looks like? Simply curious what each person on a firetruck does? In either case, you may be curious to learn more about the way fire departments are organized. Like the police or military, firefighters have ranks they achieve via promotion and skill demonstration, and every firefighter’s job is different. Here, we’ll cover the firefighter ranks, and then break down how departments and trucks are organized.

Ranks of the Fire Service

A compilation of the various ranks found in fire departments.

Firefighters are organized into distinct teams, known as companies. Their ranks are separated by chief officers and rank-and-file firefighters, although anyone in the ranks can refer to themselves as a “firefighter.” The ranks are, from top to bottom:

Fire chief
Assistant chief
Battalion chief
Captain
Lieutenant
Driver engineer
Firefighter
Probationary firefighter

1
Probationary Firefighter Affectionately known by other firefighters as “probies,” probationary firefighters are new hires who are still being trained. They aren’t officially firefighters yet, and they’re often referred to as cadets, but they’re in the process of learning everything they need to know to become one.^{[1]

Firefighter Firefighters handle the daily responsibilities of firefighting duties. They handle hoses, set up equipment, conduct first aid, enter buildings to save people, and follow orders from their higher-ups.^{[2]

- A note on the term “firefighter:” While this is an official rank, the term “firefighter” applies to every full-time employee of a fire department in this hierarchy. So, a Fire Chief could rightfully say, “I’m a firefighter,” even if they don’t hold the rank of firefighter.

Driver Engineer Different departments refer to this role differently, but they’re all interchangeable (some refer to them “Fire Engineers,” or “Fire Equipment Operators,” for example). The driver engineer is in charge of the “apparatus” (a technical term for fire trucks). The drive the truck, ensure the vehicle is clean and working correctly, and control any on-truck equipment used on site.^{[3]

- Rank abbreviation: DE, FE, or FEO
4
Lieutenant The Fire Lieutenant is in charge of training and all daily tasks, including what happens during rescues and emergencies. They relay commands from the higher-ups (who aren’t often at the station or on-site during emergencies), and they’re in charge of managing the operations of an apparatus.^{[4]

- Rank abbreviation: LT
5
Captain The captain is the main supervisor of a fire department’s daily operations, and they’re typically the highest-ranking member actually on-site at a fire department. Departments run 24/7, so departments often have multiple captains, but some smaller departments may only have one. They’re the link between the fire department’s firefighters, and the policy makers and higher-ups.^{[5]

- Rank abbreviation: CPT
6
Battalion Chief Battalion Chief is the lowest chief officer rank. They manage operations remotely but still go on calls for larger emergencies. The Battalion Chief is responsible for scheduling shifts, staffing the departments they’re in charge of, tracking sick days and vacation time, and helping to coordinate between multiple departments.^{[6]

- Rank abbreviation: BC
7
Assistant Chief The Assistant Chief oversees daily operations and runs administrative programs and initiatives. They also manage budgets, in many departments. As the title implies, the Assistant Chief also assists the Fire Chief in any way the Fire Chief sees fit, so their daily tasks can shift and change as new issues develop, but they’re often the highest ranking officer any firefighter will encounter in person when they’re on the job.^{[7]

- Rank abbreviation: AC
8
Fire Chief The Fire Chief is the head honcho of any Fire Department. They direct the department, approve budgets and personnel moves, and set the larger policies for the department. Depending on the size of the city or town, Fire Chief may be an elected or appointed position, and many Fire Chiefs will go on to run for political office.^{[8]

Firefighter Department Units

The company is the lowest fundamental unit in a fire department. A company is typically comprised of all of the firefighters necessary to operate a single apparatus (i.e. a fire truck). At minimum, a company usually consists of a captain, a driver engineer, and 2 or more firefighters.^{[9]

2
Battalion A battalion consists of multiple fire companies, and they’re always overseen by a battalion chief. Battalions normally contain 3-5 fire departments each. The point of a battalion is to ensure coordination for larger emergencies and to ensure an area always has an apparatus available should a new emergency occur.^{[10]

- Is the fire station not a unit? Usually, no. This is because stations are staffed 24 hours a day, which means you’ll often have multiple shifts where the staff doesn’t even necessarily meet. Since a single station may have, say, 15 companies and all 15 never work together at once, they’re not typically used as a key organizational element in fire departments.^{[11]

Districts are only used in larger cities where emergencies may be so large that they require multiple battalions to respond. They are typically delegated to assistant chiefs for command, and they have larger organizational considerations when it comes to emergency coordination and policy implementation.

1
Engine These are fire trucks. Firefighters refer to them as “engines,” a and there is one company per truck.^{[12]

Research source} Engines are defined by being trucks that carry firefighters while having a hose, water, and firefighting equipment. They have one captain and one engineer, in addition to 2+ firefighters.^{[13]

Research source}
- Types of Engines: There are different types of engines that are defined by their type, size, and purpose. Types 1 & 2 fight structural fires, while Types 3-7 are for wildfires. Types 1 & 2 are what most people picture when they hear the phrase “fire truck.”
- What is an “apparatus,” and why not just say “fire truck?” You may not realize it, but a fire truck is just one type of vehicle operated by a fire department. Since they use multiple vehicles, and not all of them are trucks, they use the phrase "apparatus."
2
Truck & Ladder Truck and ladder companies (sometimes called “truck companies” or “ladder companies”) are the vehicles that have large, extendable ladders on them. They’re often fire trucks, but not always. They contain a captain, an engineer, and at least 2 firefighters. These companies specialize in rescue, vertical entry, roof access, and engine support.^{[14]

- Truck and ladder companies often carry water with them, just not as much as an engine company.
- In most larger fire departments, the rank-and-file firefighters will be assigned to either a truck and ladder or an engine, but not both. They will occasionally swap between assignments, though.

Quint Short for “quintuple combination pumper,” a quint is basically a full-sized type 1 engine that has a truck and ladder. It combines the amount of raw fire-fighting power you get from an engine with the aerial support and rescue abilities of a truck and ladder. If you live in a large, modern city, the vast majority of firetrucks you see are likely quints. They contain a company of a captain, engineer, and typically 4+ firefighters.^{[15]

- You can spot quints pretty easily. They’re the giant fire trucks that have large, horizontal ladders stored on top of the entire truck.
4
Heavy Rescue Heavy rescue companies are specially trained for very specific jobs that are usually based on the geography. A mountain town may have a cave-diving team, while a seaside town is likely to have a water rescue team. The heavy rescue company is who you call when there’s a serious disaster and you need heavy duty gear to save people and manage a crisis.^{[16]

- Heavy rescue is likely to show up for things like train derailments, deadly car crashes, structural collapses, and things like that.
