Russian forces are continuing to deploy additional forces to support offensive operations in the Severodonetsk-Lysychansk area, and Ukrainian defenses remain strong.

Ukrainian Defense Ministry Spokesperson Oleksandr Motuzyanyk reported that Russian forces are transferring tanks, armored personnel carriers, engineering equipment, and vehicles from Svatove, along the Russian ground lines of communication (GLOCs) in Luhansk Oblast, to Starobilsk, just 40 km east of Severodonetsk.[1] Social media users reported that Russian forces are likely redeploying equipment from northern Kharkiv Oblast to Donbas and published footage of Russian heavy artillery arriving by rail in Stary Osokol, Belgorod Oblast on June 17.[2] UK Chief of Defense Tony Radakin stated that Russian forces are “diminishing” in power by committing large quantities of personnel and equipment for incremental gains in one area.[3] The Russian military has concentrated the vast majority of its available combat power to capture Severodonetsk and Lysychansk at the expense of other axes of advance and is suffering heavy casualties to do so.


Russian President Vladimir Putin declared that Russian forces will attack Ukrainian positions near Donetsk City but reiterated that the new tactic will require additional time during his address at the St. Petersburg Economic Forum on June 17.[4]

Putin stated that Russian forces will stop what he claimed is Ukrainian shelling of Donetsk City by attacking Ukrainian fortifications from the rear. Putin may have amplified reports of shelling of civilian areas of Donetsk City, which Ukrainian officials have denied, to discourage Western officials from supplying weapons to Ukraine.[5] Putin also declared that Russian forces will fully complete the “special military operation” in Ukraine, and noted that Russian and proxy forces will intensify counter-battery combat.[6] Putin urged Russian forces to refrain from entirely destroying cities that they aim to “liberate,” ignoring the destruction Russian forces have inflicted on Ukrainian cities and the artillery-heavy tactics Russian forces are currently employing in Severodonetsk.”[7]


Unconfirmed Ukrainian sources report that the Kremlin fired the Commander of the Russian Airborne Forces, Colonel-General Andrey Serdyukov, due to mass casualties among Russian paratroopers.

Odesa Oblast Military-Civil Administration Spokesperson Serhiy Bratchuk reported that the Kremlin appointed the current chief of staff of the Central Military District, Colonel-General Mikhail Teplinsky, as Serdyukov’s replacement and named the Deputy Commander of the Russian Airborne Forces, Lieutenant General Anatoly Kontsevoi, as the First Deputy Chief of Staff of the Russian Airborne Forces.[8][9] ISW cannot independently confirm these claims or Serdyukov’s exact role in the invasion of Ukraine, but they, if true, would indicate that Serdyukov is being held responsible for the poor performance of and high casualties among Russian VDV units, particularly in early operations around Kyiv. Continued dismissals and possible internal purges of senior Russian officers will likely further degrade poor Russian command and control capabilities and the confidence of Russian officers.


Key Takeaways

  • Russian forces continued to launch unsuccessful ground assaults against Severodonetsk and its southeastern outskirts on June 17.
  • Russian forces continued efforts to sever Ukrainian lines of communication to Lysychansk, both from the north toward Slovyansk and in the south near Bakhmut.
  • Ukrainian forces are likely conducting a counteroffensive northwest of Izyum intended to draw Russian forces away from offensive operations toward Slovyansk and disrupt Russian supply lines and are making minor gains.
  • Ukrainian forces and aviation continued to strike Russian logistics and fortifications in occupied settlements along the Southern Axis, with localized fighting ongoing.
  • Russian forces continued to regroup and transfer personnel within Zaporizhia Oblast to maintain defensive positions along the frontline.
  • Russian President Putin reaffirmed his commitment to “completing” the Russian operation in Ukraine but acknowledged that unspecified new Russian tactics (which are likely simply explanations for poor Russian performance) will take time.
  • Unconfirmed Ukrainian sources reported that the Kremlin fired the commander of the Russian Airborne Forces, Colonel-General Andrey Serdyukov, due to poor performance.
