This is the best summary I could come up with:

Russia is producing artillery shells around three times faster than Ukraine’s Western allies and for about a quarter of the cost, according to an analysis shared with Sky News.

The figures, produced by the management consulting firm Bain & Company, underline a major challenge faced by the Ukrainian armed forces as they rely on supplies of ammunition from the United States and Europe to battle Russia’s full-scale invasion.

It prompted the US, the UK and other European allies to seek to ramp up production in their respective factories, but their ability to manufacture artillery rounds still lags behind Russia’s despite a combined economic strength that far outmatches Moscow’s.

As a result, Ukrainian soldiers on the frontline say for every one round they fire against Russian positions, the invading troops can launch around five shells back.

“Often, with just one, two or three shells, we can completely destroy a target,” said Senior Lieutenant Kostiantin, an artillery battery commander with the 57th Brigade, which is fighting against a new Russian invasion into the Kharkiv region, in the northeast of Ukraine.

Sky News visited a group of new recruits in the east of the country who were learning how to use an N-LAW anti-tank missile, first provided to the Ukrainian military by the UK.
