NY Times: After a fumbled start, Russians forces hit harder in Ukraine.

Jack Watling, an expert in land warfare at the Royal United Services Institute, a defense research institution, returned from Ukraine 12 days ago and says he expects more pressure from Russian forces in the coming days. “The Russians have a lot of forces in Ukraine, and as they continue to advance in a steady pace, they can function in a combined way, and not as isolated tank columns, and they will apply a much higher level of firepower,’’ he said.

Analysts say they expect Russian forces to work to expand their hold on the pro-Russia, separatist enclaves of Donetsk and Luhansk in eastern Ukraine, and to capture a land bridge to Crimea in the south, while pushing troops down from the north to try to encircle the main Ukrainian Army east of the Dnieper River. They are trying to surround Mariupol and take Kharkiv.

That encirclement would cut off the bulk of Ukraine’s forces from Kyiv and from easy resupply, the experts say, limiting the sustainability of organized resistance. Russian troops are also moving steadily toward Kyiv from three axes to try to surround it.

While Russian forces have had supply and logistical problems — in some cases stranding vehicles without fuel in the early days of the invasion — those of the Ukrainians are likely more severe. The Ukrainian Army will start to run out of ammunition in a week, the experts suggest, and out of Stinger missiles and Javelin anti-tank missiles before then.

2. How are they refueling?

I suspect that need will likely be thwarted by every creative, think outside the box means possible.

3. What has been strange is Russia's army doesn't seem to be as state of the art as they claim

I heard them being criticized for having to do battle in the daytime as they don't have night vision, their air defense sucks, a lot of super young, untrained kids out there. They just seem totally unprepared. Seems like a lot of that military money is going into someone's pocket instead of the military.

4. The Russian military has layers of technology.

The US probably does, too.

There are a lot of older tanks. Then newer tanks. Then the newest tanks.

There are older artillery pieces and newer ones. They threw old crap at Ukraine. They don't care about the old crap. They chucked hundreds if not thousands of old armored vehicles at Ukraine in '14-'15 via Donets'k and Luhansk. That had two purposes--it used old dated stuff they were in the process of junking--lost 4 tanks you don't want to keep the new bright shiny one you do want; and the old tech was what Ukraine had, so the claim that the tanks were just those that had always been in Ukraine was believed by the gullible. (and when newer Russian tanks and munitions surfaced in video, ... uh ... what was I saying?)

The offspring said T-90s were introduced recently. https://en.wikipedia.org/wiki/T-90 They're newer. NLAWs and Javelins should work against them.

Note that when I was a data processing intern for DARCOM in the extremely early '80s the data I processed were mostly for the M-1 Abrams tank. Newest US tank isn't a redesign but revision of that tank. It's more than 40 years later. (Granted, many revisions are rather thorough-going, but still.)
