The Polish Armed Forces are composed of five branches – Land Forces (''Wojska Lądowe''), Navy (''Marynarka Wojenna''), Air Force (''Siły Powietrzne''), Special Forces (''Wojska Specjalne'') and the Territorial Defence Force (''Wojska Obrony Terytorialnej''). The military is subordinate to the Ministry of National Defence of the Republic of Poland. However, its commander-in-chief in peacetime is the President of the Republic, who nominates officers, the Minister for National Defence and the chief of staff. Polish military tradition is generally commemorated by the Armed Forces Day, celebrated annually on 15 August.
