17
Q

it consists of placing a unit on a specific section of the Fireline.

A

Sectional method

18
Q

Its mission is to stop the progress of the fire, extinguishing it at the Fireline, and execute mop-up patrol work.

A

Sectional Method

19
Q

This method is best used against a slow-moving fire.

A

Sectional method

20
Q

It is the fastest and easiest method to use on a running fire.

A

One-licked Method

21
Q

Are employed to burn back toward the advancing heads, thus creating a fast break and stopping the fire because of a lack of fuel.
