Which type of attack is characterized by a fire control line located along natural fuel breaks, favorable breaks in topography, or at considerable distance from the fire?

• A. Direct attack
• B. Backfire attack
• C. Mopup attack
• D. Indirect attack

Answer: (D)

Using a control line located away from the fire, leveraging natural fuel breaks and favorable topography, is the indirect attack approach. This tactic is chosen when direct access to the fire edge is too dangerous due to heat, flame length, or difficult terrain. By placing the line at a distance, firefighters can let the fire burn toward the protected area, or perform burnout operations to remove fuel between the fire and the line. Natural barriers like roads, rock outcrops, streams, or wide gaps in fuels slow the spread and give crews safer places to work. This differs from attacking the edge directly with a line, using ignition ahead of the fire to fight back by burning fuels, or focusing on mop-up after the fire is controlled.
