Here’s some good July 2017 satellite images of the Russian base at Buhaivka.
Like most of these larger bases, each is home to a sizable combat battle group. Located in Ukraine’s Luhansk Oblast (province), it’s close to the front line. Mid 2015 was when the first sizable Russian force pitch up here.
Since then its grown in size. Spread over several kilometers, it has a large training area and some facility military tents have been replaced by permanent buildings. These satellite images show approx 36 tanks, 50 armoured fighting vehicles & armoured personnel carriers, 30 artillery & 50 trucks/smaller vehicles. This number of around 170 vehicles matches similar combat battle groups seen in Russia’s other bases.
