The Armed Forces of Ukraine are composed of the Ukrainian Ground Forces, the Ukrainian Navy, the Ukrainian Air Force, and the Ukrainian Airmobile Forces. Ukraine's naval forces maintain their own small Ukrainian Naval Infantry force as well as their own Ukrainian Naval Aviation force. The Ukrainian Sea Guard is the coast guard service of Ukraine, however it is part of the State Border Guard Service of Ukraine and is not subordinate to the Navy. As a result of the Russian military intervention in Ukraine from 2014, the president commissioned governors of oblasts of Ukraine to create volunteer units under the government program "Territorial Defense". Initially these units received minimal funding coming from regional budgets and mostly relied on donations. In November 2014 most of the territorial battalions were integrated into Ukraine's Ground forces.
The National Guard of Ukraine serves as the main reserve component of Armed Forces of Ukraine.
Due to the ongoing hostilities with the Russian Federation, Ukraine has greatly increased the size of its military forces to 204,000 soldiers (+46,000 civil servants) in 2014, not counting paramilitary forces such as the border guards (53,000), the new formed National Guard of Ukraine (60,000) or the security service. Ukraine's armed forces came close to France, which maintained a 229,000 man force, as the largest in Europe when excluding Russia. It was reported that Ukraine's military swelled to 280,000 personnel. This was largely achieved by the repeated waves of mobilization bringing in new recruits while older soldiers had not yet been processed out, the state budget for 2015 ultimately calls for a force of 230,000. Hryhoriy Pedchenko reported that 51% of Ukraine's enlisted personnel were contract soldiers.
Military units of other states participate in multinational military exercises with Ukrainian forces in Ukraine regularly. Many of these exercises are held under the NATO co-operation program Partnership for Peace.
Since 3 June 2016 women are allowed to serve in combat units of the Armed Forces of Ukraine.
The modern military in Ukraine was completely inherited from the Soviet Union, in which Ukraine was a member state (a union republic). Like other Soviet republics, it did not possess its own separate military command, as all military formations were uniformly subordinated to the central command of the Armed Forces of the USSR. Administratively, the Ukrainian SSR was divided into three military districts (the Carpathian Military District, Kiev Military District, and Odesa Military District), three air commands, and most of the Black Sea Fleet naval bases were located on the coast of Ukraine.
As the collapse of the Soviet Union took place in 1991 (see Novo-Ogaryovo process), Ukraine inherited one of the most powerful force groupings in Europe. According to an associate of the Conflict Studies Research Centre, James Sherr: "This grouping, its inventory of equipment and its officer corps were designed for one purpose: to wage combined arms, coalition, offensive (and nuclear) warfare against NATO on an external front". At that time, the former Soviet armed forces in the Ukrainian SSR included a rocket army (43rd Rocket Army), four air force armies, an air defense army (8th Air Defence Army), three regular armies, two tank armies, one army corps and the Black Sea Fleet. Altogether the Armed Forces of Ukraine included about 780,000 personnel, 6,500 tanks, about 7,000 combat armored vehicles, 1,500 combat aircraft, and more than 350 ships. Along with their equipment and personnel, Ukraine's armed forces inherited the battle honors and lineage of the Soviet forces stationed in Ukraine. However, due to the deterioration of Russian-Ukrainian relations, and the continued stigma of being associated with the Soviet Union, most of the citations awarded to the Ukrainian units during the Soviet era were removed by the order of the President of Ukraine in 2015.
