The International Legion of the Defense of Ukraine, also commonly referred to as the Ukrainian Foreign Legion, was formed on 27 February 2022, in response to the full-scale invasion of Ukraine. The force was originally part of the Territorial Defence Forces, and eventually transferred to the command of the Ukrainian Ground Forces. The force is divided into two separate branches, one is subordinated to Territorial Defense Forces (part of Ukrainian Ground Troops), while the other one is under the command of Ukrainian Main Intelligence Directorate.
Combat Arms are troops who participate in direct combat, including infantry, armor, artillery, and other specialized units involved in ground operations to confront and defeat enemy forces.
Combat Support units provide operational assistance to combat units, enhancing their effectiveness through various functions such as logistics, reconnaissance, fire support, and medical services.
Sustainment, or combat service support, encompasses entities that deliver both direct and indirect support services necessary for the ongoing operational effectiveness of combat units.
Disbanded units are all inactive military formations that have been officially dissolved and no longer participate in operational activities.
