House of Military Officers
A House of Officers (Russian: Дом офицеров), sometimes officially referred to as the Central House of Officers or Officer Houses, is a military and cultural institution originating in the Soviet Army and present today in the Russian Armed Forces and the militaries of many Post-Soviet states. Being the Russian/Soviet equivalent to military officers' clubs in the United States, it effectively serves as cultural center serving to represent the military and to improve civil–military relations.
