Broad area of activity

Eastern front corps sector; exact boundaries are not publicly asserted here.

Notable history

Stood up in 2025 in Ukraine's shift from brigade-centric command to army corps, built around the 3rd Separate Assault Brigade's command cadre, and among the first of the new corps to be publicly presented. Its composition is only partly public — member brigades carry graded subordination on their own records.

Strengths

Inherits the 3rd Assault Brigade's recruitment brand, training pipeline and staff culture; a purpose-built corps staff rather than an improvised grouping.

Limitations

A new structure with a short institutional track record; public information on composition and boundaries is partial and contested.

Subordinate formations

Rows are layout only — position and order carry no hierarchy, importance, sequence or strength. Every record shown is an immediate subordinate of the selected organisation.

  • KRAKEN 1654 Disputed relationship · as of 2026-07 · low confidence

    What is disputed: the unit's current formal subordination. Later public reporting associates Kraken with the 3rd Army Corps, while this atlas carries it under the intelligence-linked grouping on the strength of its documented origin. Neither placement is asserted as current, and the unit is not reassigned until the relationship passes source review.
