A battalion tactical group (Russian: Батальонная тактическая группа, batal'onnaya takticheskaya gruppa), abbreviated as BTG, is a combined-arms manoeuvre unit deployed by the Russian Army that is kept at a high level of readiness.[1] A BTG typically comprises a battalion (typically mechanised infantry) 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.[2]
In August 2021, Russia's defence minister said the country had about 170 BTGs.[3] Each BTG has approximately 600–800 officers and soldiers,[4] of whom roughly 200 are infantrymen, equipped with vehicles typically including roughly 10 tanks and 40 infantry fighting vehicles.[5]: pp. 11–13
