In April 2014, Minister of Internal Affairs Arsen Avakov issued an order to create battalions of special purpose within the Ministry of Internal Affairs structure. Their goal was to protect public order and important facilities across Ukraine, but all of these units were eventually sent to the east to counter Russian aggression. After the reformation of National Police in 2015, the units were reformed as Special Task Patrol Police units.
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.
