guard construction.
34
The removal of surface, lateral and aerial fuels.
35
Constructing Guard

• Dozer blades angled away from fire
• Lead dozer to walk down timber
• Second dozer pushes walked down timber away from
  fire
• Third dozer bares to mineral soil
• Generally 1-1.5 blades wide

METHODS OF ATTACK
38
Direct attack on smaller fires, quieter flanks on
larger fires.
39
Parallel attack supported by back fire operations
40
Indirect Dozer guard Supported by
burnout Operations.

Dozer guard being supported by ground crews
water tenders after burnout operations
42
Skidders with tanks Supporting dozer guard.
43
Rubber-tired Water Tenders are for guard support.
44
Manpower supporting dozer guard.
45
Guard build for indirect attack burnout
operations, supported by air tankers
46
Larger fires, 2 or more units should work
together. Guard is generally wider. 2 dozer
widths walk down on inside of guard to
support torching operations.
