The boys were given the notices by the chief Russian military recruiting officer in the Simferopol district of Crimea, the Moscow-installed Justice Ministry for the region said on its website, Radio Liberty reports.
The documents were presented as part of a celebration of “the glorious sons of Russia” marking Defenders of the Fatherland Day, the February 23 holiday honoring the Russian military — and, unofficially, all Russian men.
The ministry said the notices indicated the boys should report for military service on January 24, 2032.
That date was a mistake, according to the website meduza.io, which pointed out that Russian males are obliged to register for military service when they turn 17 — an age the three boys will not reach until 2033.
Russia seized control of Crimea from Ukraine in March 2014 after supporting a takeover of the regional legislature, sending in troops widely known as “little green men” for their unmarked uniforms, and staging a referendum dismissed around the world as illegitimate.
