The main responsibility for the defence of the Kuril Islands falls to the 18th Machine Gun Artillery Division of the Eastern Military District. The headquarters of the Division are located in Goryachiye Klyuchi on the Iturup Island. It also has garrisons on Kunashir Island and Shikotan Island. The 18th Artillery Division was previously the only division-strength military unit remaining in the Armed Forces of Russia, along with the 201st Military Base in Tajikistan. The division's aging infrastructure is in need of overhaul. There are also Border Guard Service troops stationed on the islands.
