headlines: Russia Advances Behind Brutal Barrage, but Will Its Strategy Keep Working?
articles: Russia’s capture of the cities of Sievierodonetsk and Lysychansk, a significant victory for Moscow’s campaign to conquer eastern Ukraine, demonstrates the success of the Russian military’s grinding strategy based on superior firepower and incremental advances.
  
  It also raises serious questions about how long either side can keep going like this, particularly the battered and vastly outgunned Ukrainian forces, forced to rely on raw recruits and suffering heavy casualties, along with the mental strain of combat, retreat and constant Russian shelling.
