I understand that they are on standby. Ground is soft and they’ll bog down they are so heavy. That is why they are having problem with the leopards, etc. They have to run them on roads and the Russians just sit back and monitor the roads and when the dumb Ukrainians run them down the roads they pick them off.
As usual, the fantasy is that the Ukrainians could run offensive operations without complete air cover. They found out the hard way.
“Full air cover” would have only added lawn darts to a train wreck.
