They are assigned to observation posts, checkpoints, and guard areas of the Russian 11th Air Assault Brigade troop concentration.
This allows Russia to release some of its own military personnel and redirect them to the frontlines.
On Dec. 1, Ukrainian Main Intelligence Directorate spokesman Andriy Chernyak said that three North Korean generals undergoing training in Russia's restricted access camps are very well guarded and hidden from everyone.
The 11,000 troops they will command are also undergoing general military training in Russia’s Kursk Oblast, as well as specific training to operate unmanned aerial vehicles (UAVs)
“We do not yet know in what role they will take part in hostilities, but we understand that those soldiers who survive and return to North Korea will have a modern knowledge of warfare” and are likely to become instructors for the million-strong North Korean army, Chernyak said.
