Battalion Tactical Group

A battalion tactical group, abbreviated as BTG, is a combined-arms manoeuvre unit deployed by the Russian Army that is kept at a high level of readiness. A BTG typically comprises a battalion of two to four companies reinforced with air-defence, artillery, engineering, and logistical support units, formed from a garrisoned army brigade. A tank company and rocket artillery typically reinforce such groupings. BTGs formed the mainstay of Russia's military intervention in Ukraine from 2013 to 2015, particularly in the war in Donbas.
