Serhiy Zgurets, Ukrainian military expert and CEO of the media and consulting company Defense Express, made this statement on Espreso TV.“We must acknowledge that the enemy currently holds a manpower advantage in many sectors,” Zgurets noted. “However, this advantage can be neutralized by several key factors — effective leadership, well-trained personnel, and the correct use of tactical methods adapted to the terrain, whether the defense is held by brigades or corps formations. The reorganization of the Ukrainian Armed Forces into a corps structure is now underway, and this process is extremely challenging.”He emphasized that the complexity stems from the need to defend active front lines while simultaneously deploying and integrating brigades into the corps system within their new areas of responsibility.“Not all corps have achieved this level of integration, and most brigades remain dispersed, making it difficult to concentrate forces,” noted Serhiy Zgurets. “However, the Third Army Corps—built around the Third Assault Brigade—breaks this mold. It is currently holding defensive positions in the Kharkiv region and northern Donbas, stretching from Zahyryzove down toward Lyman and Borova on the eastern bank of the Oskil River.”He emphasized the scale of their responsibility: “The front held by the Third Army Corps spans approximately 150 km, which represents about 12 percent of Ukraine’s entire frontline.”“On this sector, the Third Army Corps not only holds the line but also conducts effective counterattacks,” explained Serhiy Zgurets. He noted that, according to recent military statistics, Ukrainian losses on this stretch have been halved since transitioning to the corps structure, compared with the period when brigades operated independently.“This improvement is thanks to the Third Army Corps’ command under Andriy Biletskyi,” Zgurets continued. “Their approach minimizes our own casualties and enables counteroffensives based on tactical necessity—not merely to generate favorable reports for senior leadership.”Zgurets argued that this example demonstrates how high-quality leadership can enable both defensive resilience and offensive success, even against numerically superior forces.However, he cautioned that the corps-based reorganization is still in progress and not uniformly successful: “While the Third Assault Corps is a positive example, there are some corps that struggle to manage their assigned sectors. Forming new corps amid active hostilities brings both advantages and challenges, and some commanders are finding it difficult to cope.”
