Suppression Tactics & ICS

Req 7a4 — Hand Crews & Aircraft

7a4.

Use of hand crews, machinery, and aircraft

Modern wildfire suppression relies on coordinated operations combining ground forces, heavy equipment, and aviation resources:

  • Hand Crews (Hotshots & Type 2 Crews): 18 to 20 firefighters equipped with hand tools (Pulaskis, McLeod tools, chainsaws) who dig firelines, cut brush, and conduct burnout operations in steep terrain.
  • Machinery (Bulldozers & Tractor-Plows): Heavy machinery used to rapidly scrape wide containment lines through dense brush and timber.
  • Aircraft (Air Tankers & Helitack): Fixed-wing air tankers drop long-term chemical fire retardant to slow fire spread, while helicopters (helitack) drop water buckets directly on hot spots to cool the fire for ground crews.
