Russia has reorganised its military command - Western official

A Western official confirmed Russia had now reorganised the command of its operations in Ukraine with the general now in charge having had extensive experience from Syria.
The forces which invaded on 24 February were organised and commanded separately from the district from which they had come.
“There was really poor coordination across those different commands,” said the official, since Russian forces had never trained to work in this way. The Southern Military District Commander is now in charge of operations to attempt to provide better co-ordination - this is reported to be General Alexander Dvornikov.
“That particular commander has a lot of experience of Russian operations in Syria. So we would expect the overall command and control to improve,” the official said.
In terms of timing, the Western official thought political imperatives might take precedence over military priorities in Russia pushing forward to get some kind of success ahead of 9 May when the country marks victory in World War II. Western officials said they were seeing the piecemeal sending of more forces towards Donbas rather than pausing to allow forces to regroup properly.
“There's a tension between the military logic of getting the force properly set for a reinvigorated Russian operation into the Donbas, potentially using more appropriate tactics and learning some of the lessons from the disastrous operations largely so far, against a political imperative to actually get on with the operation and move quickly,” said the official.
Russia is thought to have slightly fewer than 100 battalion tactical groups available for operations, once they have been reconstituted after current moves. This would be a "substantial" Russian force but the official said Russian tactics have meant that even with numerical advantages they have been held back by smaller numbers of Ukrainian units acting in a far smarter way and with surprise.
“Unless Russia is able to change its tactics, and be far more effective at using all the tools to its advantage, if it fails to do that, then it's very difficult to see how they succeed in even these limited objectives that they've reset themselves, and certainly not at the pace that I think they would hope to do," the official said."
