Ukraine faces severe challenges, primarily in recruiting enough personnel, leaving front-line units short on infantry and increasingly brittle. Russia has also made advances in drone warfare that some analysts say has neutralized what was once a Ukrainian advantage. Russia this month claimed its first major conquest in more than two years, the city of Pokrovsk, although Ukraine disputes its capture.
But senior Western military officials and front-line Ukrainian officers say that Russia’s military isn’t on the verge of a breakthrough. Though Kyiv’s military position has been gradually eroding, its forces are still inflicting heavy casualties, meaning small Russian gains come at heavy cost.
