Armed Forces of Ukraine
The Soviet Union required all able-bodied male citizens to serve two years in the armed forces (three years if drafted into the navy), although the draft could be postponed due to continued higher education. It was possible to be drafted into non Ministry of Defense military forces such as the KGB Border Guards, the Militsiya, or the Internal Troops. When Ukraine gained its independence it retained the policy of conscription, although the time in service was reduced to 18 months in the navy and one year in all other services. Ukraine also gradually began recruiting professional soldiers, although in almost all cases a person had to serve as a conscript prior to becoming a professional soldier. The Ukrainian Naval Infantry was the first service to convert to being staffed by fully professional marines.
