3rd Army Corps
Army corps stood up in Ukraine's 2025 corps reform around the 3rd Separate Assault Brigade as its core formation.
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.
