Elderly.

Inexhaustible manpower the traditional Russian muzhik in time of war no longer a given?

"The term 'muzhik' . . . means 'Russian peasant'" 

"Putin Raises Elderly Army as Ex-Servicemen Up to 70 [years of age] Deemed Eligible"

From Newsweek ^ | July 22, 2023 | Brendan Cole the tip from Freeper.

"Russian lawmakers have passed legislation changing the age categories for those called up for the military potentially meaning that older troops could be sent to fight in Ukraine. With President Vladimir Putin's forces reportedly facing heavy losses in his invasion of Ukraine, Russia's parliament, the Duma, has this week passed a raft of measures to help with mobilization, including tougher fines for those who avoid the draft as well as extending upper age limits for reserves."

Men [age seventy or even greater] way too old to engage in physical mortal combat on the battlefield! Leave the fighting itself to the younger men.

Reservists and retired personnel with esoteric military expertise and those experienced in service & service support roles too can perform a vital function. This I must admit and readily do so.

"esoteric: adjective - * Intended for or understood by only a small group, especially one with specialized knowledge or interests: synonym: mysterious. * Relating to or being a small group with specialized knowledge or interests. * Not known by or suitable for the public; private."

Recall in addition that previous blog entry the American retired serviceman even beyond age sixty-five years can be recalled to active duty in a period of special circumstances.
