Bakhmut Now - UK MoD

For every 48 centimeters of captured territory, the Russians lost one occupant, killed or wounded.

"In February 2022, Russia probably planned to complete the capture of the entire Donbas within 10-14 days. But in Bakhmut, one person is killed or wounded for every 48 centimeters of positions gained. Ukraine continues to fight", - Ministry of Defence of UK.
