Which of the following is NOT listed as a wildland fire part?

• A. Smoke
• B. Head
• C. Rear
• D. Green

Answer: (A)

Wildland fire parts refer to the sections of the advancing fire front: the head, the rear, and the flanks. The head is the leading edge that moves outward with the wind, the rear is the trailing edge on the opposite side, and the flanks are the sides between head and rear. Smoke isn’t a structural part of the fire front—it's the plume produced by burning. Green describes vegetation status (unburned or fuel state) rather than a component of the fire’s edge, so it isn’t a defined fire-front part either. Therefore, the item not listed as a wildland fire part is smoke.
