or one of its branches that shelters military equipment and personnel, and facilitates training and
operations. A military base always provides accommodations for one or more
units, but it may also be used as a
command center,
training ground or
proving ground. In most cases, military bases rely on outside help to operate. However, certain complex bases are able to endure on their own for long periods because they are able to provide food, drinking water, and other necessities for their inhabitants while under siege. Bases for
military aviation are called
air bases. Bases for
military ships are called
naval bases.
Jurisdictional definition
Military bases within the United States are considered
federal property and are subject to
federal law. Civilians (such as family members of
military officers) living on military bases are generally subject to the
civil and
criminal law
Criminal law is the body of law that relates to crime. It proscribes conduct perceived as threatening, harmful, or otherwise endangering to the property, health, safety, and Well-being, welfare of people inclusive of one's self. Most criminal l ...

Military bases can range from small outposts to military cities containing up to 100,000 people. A military base may belong to a different nation or state than the territory surrounding it.

Base (Log base) and a
Fire Base (FB).
A military base may also contain large concentrations of military supplies in order to support
military logistics. Most military bases are restricted to the public and usually only authorized personnel may enter them (be it military personnel or their relatives and authorized civilian personnel).
In addition to the main military facilities on a certain installation, military bases usually (but not always) have various different facilities for military personnel. These facilities vary from country to country. Military bases can provide housing for military personnel, a post office and dining facilities (

Bases used by the
United States Air Force Reserve tend to be active USAF bases. However, there are a few
Air Reserve Bases, such as
Dobbins ARB, Georgia, and
Grissom ARB, Indiana, both of which are former active-duty USAF bases. Facilities of the
Air National Guard are often located on civil airports in a secure
cantonment area not accessible to the general public, though some units are based on USAF bases, and a few ANG-operated bases, such as
Selfridge ANGB, Michigan. Support facilities on Air National Guard and Air Force Reserve installations tend to not be as extensive as active bases (i.e., they usually do not have on-base lodging (though
Kingsley Field ANGB, Oregon, is an exception), clinics (except for drill days), or retail stores (although some have small convenience stores)).
In Russian usage "military base" or "naval base" is not limited to denoting a specific fence described facility and usually encompasses a broad territory within which a number of discrete facilities may be located. As examples, 1) the Russian Sevastopol Naval Base comprises individual facilities located within the city of Sevastopol proper (waterfront moorings, weapons stores, a headquarters compound, and a naval infantry base) as well as an airfield at Kacha north of the city; 2) the Leningrad Naval Base comprises all naval facilities in the greater St. Petersburg area including training schools, commissioning institutes, the naval academy, and the Kronshtadt base on Kotlin island.
Overseas military base
An overseas military base is a military base that is geographically located outside of the territory of the country whose

are the principal occupants of the base.
Such bases may be established by treaties between the governing power in the host country and another country which needs to establish the military base in the host country for various reasons, usually strategic and logistic.
Furthermore, overseas military bases often serve as the source of the
military brat subculture due to the children of the bases' occupant military being born or raised in the host country but raised with a remote parental knowledge of the occupant military's home country.
British military bases
In the 18th and 19th centuries the
Royal Engineers were largely responsible for erecting military bases in the British Isles and the British Empire. In 1792 the Chief Engineer was instructed to prepare the Barrack Construction estimates for Parliament and at the same time the Department of the Barrackmaster-General was established.
During the period from the 1840s through the 1860s barracks were constructed under supervision of the
Royal Engineers in:

stone frigates.
