This article analyzes the guerrilla activities of Kasym Kaysenov during the Great Patriotic War from military-historical and tactical perspectives. The aim of the study is to examine Kaysenov's sabotage and reconnaissance-assault operations in the context of the theories of "small war" and irregular warfare, as well as to identify their military-tactical models.

The study's sources include Kaysenov's memoirs, the memoirs of his contemporaries, official military documents, and later scholarly reconstructions. Historical-comparative, source-based, narrative, and tactical-situational reconstruction methods were used.

As a result of the study, guerrilla episodes, previously considered primarily journalistic and heroic in nature, were reinterpreted as real military operations, and a typology of tactical solutions employed in Kaysenov's practice was proposed. The impact of these tactics on the effectiveness of the regional partisan movement and the course of World War II as a whole was determined.

The scientific novelty of this article lies in K.'s presentation of the results of a systematic analysis of partisan actions led by Kaysenov as a military-strategic phenomenon and their reinterpretation in the context of modern military history and theories of "small war."
