British Defence Intelligence Update Ukraine – 15 October 2022 - Kyiv Post

Contingents of mobilised Russian reservists have been deployed to Ukraine over the last two weeks. Their average level of personal equipment is almost certainly lower than the already poor provision of previously deployed troops.
Many reservists are likely required to purchase their own body armour, especially the modern 6B45 vest, which is meant to be on general issue to combat units as part of the Ratnik personal equipment programme. This vest has been selling on Russian online shopping sites for 40,000 roubles (approx. USD $640), up from around 12,000 roubles (appox. USD $190) in April.
In 2020, the Russian authorities announced that 300,000 sets of Ratnik body armour had been supplied to the Russian military, which was ample to equip the force currently deployed in Ukraine. Endemic corruption and poor logistics remain one of the underlying causes of Russia’s poor performance in Ukraine.
