Battalion tactical group
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. 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.
