I can most definitely post evidence as you ask Alex straight out of Moscow in fact, dated on Monday:

Just in case you are struggling to click on the link I will outline for you:
'Russian troops stationed in the town of Dolbino near the Ukrainian border have been living in “nightmare” conditions, sleeping on cramped floors and going without military food rations for days, according to social media reports and rights advocates interviewed by The Moscow Times.
The soldiers from the Taman and Kantemirovskaya Divisions are stationed in the town of Dolbino 30 kilometers from the Ukrainian border. They have gone without food rations and proper accommodation for the last five days, with soldiers forced to pay out-of-pocket for supplies.
The conditions were first noticed after local residents reported an influx of soldiers and conscripts who claimed they had been left at the train station by military officers.
Locals reported providing conscripts with food and water after some recruits claimed to have run out of money.
“We are not sure why, but there was clearly a violation of usual practice,” Svetlana Golub, the head of the Soldiers' Mothers Committee, an NGO that advocates for soldiers’ rights, told The Moscow Times on Monday.
This is straight out of Russia, first hand evidence.
Given this was FIVE days ago, I should think the poor chaps are in pretty bad shape by now
Hence the most inconvenient 'pause' in the miltiary operation.
