"The euphoria I could have felt when I visited Kiev a year ago has largely faded, giving way to extreme exhaustion," he said. Soldiers returning from the front lines are tired and openly admit it. Ferguson also stressed that no modern weapons can fully compensate for the lack of experience of the forces themselves."The main problem is that relatively weak forces that do not have air superiority are advancing towards well-fortified Russian positions," according to Bloomberg.The Ukrainian armed forces began a counteroffensive against Russian forces since last June, but have not made any progress despite using all weapons. According to Russian President Vladimir Putin, the Ukrainians have not been able to achieve any results, while Western military experts say that the reason for the failure of the Ukrainian counteroffensive is the effectiveness of Russian fortifications and minefields, due to which the Ukrainian armed forces suffered heavy losses.
