Second enlistment or starting with conscripts?

After retiring, many people still miss their life in bloody barracks, so they choose to join the army for the second time. Soldiers who enlist for the second time have already served before, so should they continue to start from the most basic conscripts after re-enlisting? After joining the army for the second time, you still have to start from the conscripts, not counting the previous service years, and you will be directly promoted to the non-commissioned officers.
