It probably remained a 3rd for San Diego Fire Department but that likely didn't include the large Federal Fire response from the Navy and other military facilities in the area.
San Diego assigned 5 engines and 2 ladders per alarm.
National City, Coronado, and Chula Vista were also on the scene.
Federal FD had 10 engines and 2 ladders available to use (2 additional engines are on San Clemente Island)
San Diego was simultaneously working a major MVA response and a 1st alarm brush fire
