The 30-year-old man, whose identity was not made public, was drafted into the military in 2003 and was stationed in the remote Kamchatka peninsula for one year before fleeing the army's ranks, police said.
"He lived in Kamchatka all this time, mainly hiding in the forest," the regional branch of the interior ministry said in a statement. "He got by with odd jobs and did not attempt to get in touch with his family."
TASS news agency reported that the deserter's family had even buried who they thought was their missing relative.
The soldier would have deserted because of "family problems," TASS quoted regional authorities as saying.

The deserter reportedly had built himself a home out of old construction materials on the outskirts of Petropavlovsk-Kamchatsky, and made a living by working on a private pig farm and collecting scrap, among other odd jobs.
Valentina Melnikova, the head of Russia's Committee of Soldiers' Mothers, told AFP she doubted the soldier would receive prison time for his offence.
"There were lots of deserters in those days in the Far East. We've had cases when some would hide in a basement for years, but they would go through a psychiatric examination and would be set free," she said.
The Chief Military Prosecutor's office did not reply to a request for comment.
