Ukrainian troops are suffering massive losses as they are outgunned 20 to one in artillery and 40 to one in ammunition by Russian forces, according to new intelligence painting a bleak picture of the conflict on the frontline.For the first time since the war began, there is now concern over desertion. The report, seen by The Independent, says the worsening situation in the Donbas, with up to a hundred soldiers being killed a day, is having “a seriously demoralising effect on Ukrainian forces as well as a very real material effect; cases of desertion are growing every week”.
