What is the difference between direct attack and indirect attack?

What is the difference between direct attack and indirect attack?

• A. Direct attack uses air support; indirect uses ground lines
• B. Direct attack applies suppression actions at the fire edge; indirect attack uses lines or fuels management away from the fire to control
• C. Direct attack only for ground fires; indirect for canopy fires
• D. Direct attack is the same as indirect attack

Answer: (B)

The main concept is recognizing where suppression actions are applied relative to the fire edge. A direct attack targets the fire edge itself, applying cooling and extinguishing actions right at the flaming perimeter to stop the fire by directly interrupting heat and flames. An indirect attack, on the other hand, uses containment lines or removal/management of fuels away from the fire to control it—slowing spread and creating a barrier before the flame front reaches those areas. This is why indirect tactics are chosen when conditions make it unsafe or impractical to fight at the edge, such as with heavy fuels or intense, fast-spreading fires. Direct attack is typically used when conditions and access allow near the edge to quickly suppress the flames. The other options mix up the idea (air support versus ground lines) or imply equivalence or restriction to certain fire types, which isn’t how the distinction is defined.
