The Russian Invasion

Here's something that caught my eye:

From the Financial Times:

A difference of 3mm encapsulates the challenges the west faces as it works out how to supply the weapons that Ukraine needs to hold off, or even repel, Russian forces during the next phase of the war: the looming battle for the Donbas. 

The list of weapons that Ukraine wants includes more long-range artillery to target the Russian positions that have been shelling its cities during six weeks of heavy fighting. However, most Nato countries’ heavy artillery has a 155mm calibre while Ukraine, as part of its Soviet legacy, uses 152mm. 

 “The Ukrainians are running out of 152mm ammunition. Where are they going to get it?” asked Chris Donnelly, an adviser to four former Nato secretaries-general on the Soviet and Russian military. “No one in the west uses it or makes it apart from the Serbs — and they’re on Russia’s side.” 

Looking for more detailed accounts of the military action in Ukraine than you can find in the New York Times or Washington Post?  The best I've found so far (and it's plenty for me) is Critical Threats, a website of the Institute for the Study of War. Critical Threats offers reliable reports and assessments of military activity in Ukraine. It is often used as a source by the Financial Times and the newspapers above.
