The Russians, unlike Joe’s folks, will not tell you exactly what they plan to do.
Winter is coming and that’s prime Russian fighting weather.
I think Putin plans a massive push with experienced troops, with the 300,000 new draftees expected to hold the existing lines.
The Russians tend to be conservative. They might talk nuclear, but talk isn’t walk.
He is not calling draftees but reserves.
Its those “experienced troops” that need to have their ranks refilled with replacements. Divisions are in brigade strength, brigades are battalions, etc. The whole Russian army needs large numbers of individual replacements.
Ex. Kherson - there are supposed to be three VDV (Airborne) divisions, a motor-rifle Division, three detached brigades, a special forces brigade, misc DNR and security (ministry of the interior) and independent artillery units there, besides engineering and service units. Full strength that lot should be close to 100,000 men on the east bank of the Dneipr. But the consensus seems to have them at 25,000.
This seems to be the case all along the line. I expect that the call-up is mainly intended to provide replacements to all the depleted units, not create new ones. Russia probably doesnt have the cadre to set up many new units from scratch, and these will take time. Russia hasnt got much time.
