What term describes extinguishing a wildland fire's edge while moving along the perimeter using short handlines?

• A. Mobile attack (pump and roll)
• B. Direct attack
• C. Indirect attack
• D. Mop-up

Answer: (A)

Moving along the fire’s edge while knocking it down with short handlines from the engine is known as a mobile attack (pump and roll). This approach targets the edge itself as you progress around the perimeter, using small, quickly deployed lines so the apparatus can keep moving. The goal is to prevent the flame from creeping into unburned fuel by immediately cooling and suppressing the edge as you advance.

This differs from a direct attack, which focuses water directly on the flame front and may involve more stationary or fixed-position work rather than continuously moving around the perimeter with short lines. An indirect attack aims to slow the fire or redirect it by cooling fuels ahead of the head or creating control lines farther back, not by attacking the edge as you move along it. Mop-up refers to extinguishing remaining hotspots after the main fire is controlled, not the live-edge progression technique described.
