* '''Structural firefighting ''' is fighting fires involving [[building]]s and other structures. Most city firefighting is structural firefighting. Structural firefighting is what most people think of when they think of what their local "fire department" does.* '''Wildland firefighting ''' is fighting [[forest]] fires, brush or bush fires, and fires in other undeveloped areas. The [[United States Forest Service]] and other government agencies which administer public lands hire a large number of wildland firefighters every [[summer]], when fire conditions are at their peak.* '''Proximity firefighting ''' is fighting fires in situations where the fire produces a very high level of heat, such as [[aircraft]] and some [[chemical]] fires. Proximity firefighting is not the same thing as structural firefighting and in some (but not all) cases takes place outdoors.* '''Entry firefighting ''' is a highly specialized form of firefighting involving the actual direct entry of firefighters into a fire with a very high level of heat. It is not the same thing as proximity firefighting, although it is used in many of the same situations (such as flammable liquid fires).
