Russian President Vladimir Putin has signed a law scrapping the upper age limit for Russians and foreigners to join the military as contract service members, according to Russian state news agency TASS.
Russia’s State Duma passed the bill on Wednesday but Putin's signature was needed for it to become law.
Previously, citizens aged 18 to 40 and foreigners aged 18 to 30 could enlist in the Russian military.
The changes were drafted by the head of the State Duma Defense Committee, Andrei Kartapolov, and his first deputy, Andrei Krasov. According to TASS, they believe the abolition of an upper age limit will attract specialists in areas such as medical support, engineering and communications.
The explanatory note to the draft law also notes that the use of high-precision weapons and military equipment requires specialists and they gain the experience by the age of 40 to 45.
The changes in law come amid serious Russian casualties in Ukraine, where Moscow is waging what it euphemistically calls a "special military operation."
Russia also has a system of military conscription. The Kremlin initially said draftees would not serve in Ukraine but subsequently acknowledged they were serving in combat.
