Ukraine’s slow progress piles pressure on west to keep up supply of weapons

Jack Watling and Nick Reynolds, in a new paper from the Rusi thinktank, estimate that Ukraine has been making “approximately 700–1,200 metres of progress every five days”, taking care to spare lives and western equipment. But there are, Watling adds, second and third Russian lines, defensive positions estimated at 20 miles deep. Moscow’s defenders are also laying further mines, sometimes with the help of drones, whose density may be less certain, but whose threat is significant enough.
