Army Bases in California

California is a large state, and with that comes a large number of military bases.

The state holds 8 Army bases total, 5 of which currently house Active Army units, 2 of which house Reserve or National Guard units or training, and one of which is completely inactive at this time.

Many of California’s Army bases were founded during the time of the Second World War, while a couple were formed in the early-to-mid 1800s. 

These various founding dates show that every base in California has a rich history as well as a unique way of running today.
