Main Intelligence Directorate

INTELLIGENCE BRIEFRF FORCES
Commander: Major General Ruslan Kosygin

Identity

This record best matches the Main Intelligence Directorate of the Belarusian General Staff, not a separately documented field base. The clearest public-source picture is an organizational command node inside the General Staff structure; the publicly listed Ministry of Defence address in Minsk should not be treated as a confirmed dedicated office for the directorate.

Leadership

The supplied commander name appears outdated. Reporting on 28 July 2023 said Major General Ruslan Kosygin was removed from this post and replaced by Major General Vladimir Kupriyanyuk; official sanctions listings in 2024-2025 still identify Kupriyanyuk as Head of the Main Intelligence Directorate and Deputy Chief of the General Staff, while Kosygin appears in official CSTO parliamentary roles in 2024-2025.

Subordinate SIGINT sites

The two placemarks are consistent with the best-corroborated subordinate formations tied to this command: the 153rd Special Purpose Radio-Technical Brigade at Volozhin and the 255th Special Purpose Radio-Technical Regiment at Navahrudak. ICDS places both under General Staff control, and 2023 open-source reporting linked unit 30695 to the 153rd brigade and unit 75158 to the 255th regiment.

Mission

ICDS describes the 153rd and 255th as radio-technical units responsible for radio reconnaissance and signals-intelligence tasks, grouped with the 228th Electronic Warfare Regiment under the General Staff. Separate 2023 reporting that the 255th was recruiting operators with Lithuanian, Latvian, Polish, and English is consistent with western-border collection requirements, but the directorate's exact equipment, collection architecture, and tasking are not publicly confirmed.

Confidence limits

Public reporting is not fully consistent on the 255th regiment's higher-level subordination: ICDS places it under the General Staff, while other open-source listings have associated it with the Western Operational Command or later Belarusian special troops. The location record is therefore strong as a Main Intelligence Directorate-associated command node, but exact administrative relationships below directorate level should be treated cautiously.
