The Naval and Marine Corps Reserve Center was built between 1938 and 1941 by the Works Progress Administration (WPA) in the Art Deco style as part of the "New Deal". The Naval and Marine Corps Reserve Center was designated a California Historic Landmark (No.972) on Sept. 19, 1989. The site is currently known as the Frank Hotchkin Memorial Training Center and serves as the training center for the Los Angeles Fire Department. The Naval and Marine Corps Reserve Center is located just north of Downtown Los Angeles in Chavez Ravine, next to Dodger Stadium at 1700 Stadium Way. The Naval and Marine Corps Reserve Center was the second Navy Reserve Center built in the United States. During its operation it was the largest Reserve Center, training over 250,000 sailors and Marines. The main building is two-stories tall and has 90,000 square-feet of floor space. The United States Armed Forces ended operations in the building in 1995. Naval and Marine Corps Reserve Center was built with a pool, damage control training room, rifle range and the mock up of a deck of a ship, a space that looked and worked like a sea vessel. The "deck of the ship" has World War II antiaircraft guns and cannons. During World War II 20,000 sailors were trained at the center. California architects Robert Clements and Associates declared the building "Designed as the largest enclosed structure without walls". The 1st Civil Affairs Group was activated June 6, 1985, originally as 3rd Civil Affairs Group, and stationed at Naval and Marine Corps Reserve Center in Los Angeles, between 1987 and 1988, the group recruited and trained Marines to fulfill its mission of providing civil affairs support to active forces in training exercises in the United States and overseas. In 1988 the 1st Civil Affairs Group moved to Marine Corps Base Camp Pendleton.

The Los Angeles Fire Department provides firefighting services as well as technical rescue services, hazardous materials services and emergency medical services to the citizens of the city of Los Angeles, California, United States. The LAFD is responsible for approximately four million people who live in the agency's 471 square miles (1,220 km2) jurisdiction. The Los Angeles Fire Department was founded in 1886 and is the third largest municipal fire department in the United States, after the New York City Fire Department and the Chicago Fire Department. The department is sometimes also referred to as the Los Angeles City Fire Department or "LA City Fire" to distinguish it from the Los Angeles County Fire Department, which serves unincorporated areas and, via contracts, other incorporated municipalities within Los Angeles County without their own fire departments. The department is currently under the command of Chief Kristin Crowley.
