A large portion of the training area at the Marine Corps Base at Camp Pendleton is designated strictly as impact zones for live-fire training ranges Marines regularly conduct. Due to the constant live-fire training, vegetation fires on impact zones are common but they aren’t always put out as most would expect, according to their website.

“The number one reason that we don’t engage impact zone fires is for safety,” said John Crook, the deputy chief of the Camp Pendleton Fire Department. “We don’t want to put anyone in there if we don’t have to.”
