<P> A heavy rescue vehicle, sometimes referred to as a Rescue Company, Rescue Squad or Technical Rescue, is a type of specialty firefighting apparatus . They are primarily designed to carry specialized equipment for technical rescue situations such as vehicle extrications following traffic collisions, confined space rescues, rope rescues, swiftwater rescues, or building collapses . </P> <P> In addition to fire and rescue departments, tram or railway companies may have their own dedicated heavy rescue squads . For example, railway rescue squads may carry very specialized equipment, for railway accidents, like hydraulic jacks with capacity for lifting locomotives or even moving them horizontally, and equipment for tank car accidents . </P> <P> Wildland firefighting requires vehicles that can easily negotiate difficult terrain and high - gradient roads, be self - reliant, and have high clearances for wheels and suspension . These wildland fire engines are traditionally smaller than standard fire apparatus and are primarily used for vegetation fires or wildland fires . They may also respond to emergencies in rough terrain where other vehicles cannot respond . Most wildland engines feature four - wheel drive capability to improve hill climbing and rough terrain capability . Some wildland apparatus can pump water while driving (compared to some traditional engines which must be stationary to pump water), allowing "running attacks" on vegetation fires to minimize the rate of spread . </P> <P> Fire departments that serve areas along the wildland--urban interface are faced with unique challenges that departments based in larger cities or strictly rural areas do not need to worry about . Departments in these areas often elect to use a type of fire engine commonly referred to as a wildland - urban interface engine or simply interface engines . While technically considered a wildland fire engine by many, these maintain the traditional look and feel of a standard engine . </P>
