While serving as commander of the long-range aviation of the russian air force, he exercised direct strategic command of the strategic aviation forces involved in launching massive missile strikes on the territory of Ukraine. There are reasonable grounds to believe that the person was involved in organizing and giving orders to use air-launched cruise missiles against energy and civilian infrastructure facilities that were not military targets, resulting in numerous casualties among the civilian population and extensive destruction.

For the first time since the end of World War II, under the command of S. Kobylash, heavy bombers resorted to carpet bombing of densely populated areas, in particular in Mariupol.

These actions are part of the russian aggressive war against Ukraine and at the same time contain signs of violations of the laws and customs of war. At the same time, the person did not exercise the right to refuse to carry out a clearly criminal order, the obligation not to carry out which is provided for by international law, thus becoming an accomplice to the crime.
