The IMRB’s anti-aircraft and anti-tank capabilities are organized in battalions. They used to be single batteries in old MRRs. Most of today’s combat support and service is provided by battalions compared with companies in Soviet times. The old MRR relied more on support and service from the division level.
The 138th IMRB’s motorized rifle battalions have about 500 personnel with about 100 men in each of three companies operating ten MT-LB light armored vehicles. A battalion probably has 31 MT-LBs. The MT-LB is also the prime mover for other sub-units, so the brigade has a significantly larger total inventory, often put at 159 in all. For example, artillery battalions have eight each and anti-tank gun batteries have six.
For integral fire support, each motorized rifle battalion has a battery of six towed 120-mm 2B16 Nona-K gun-mortars in two firing platoons of three weapons. The battalion has a man-portable 9K115 Metis ATGM battery of three platoons of three launchers. The battalion has an air defense battery organized similarly with three platoons of three hand-held 9K38 Igla SAMs.The 138th is one of several MR brigades primarily using venerable MT-LBs rather than more modern BTRs or BMPs. The 25th near Pskov is another. Others are in mountainous areas of the North Caucasus or in the Eastern MD. The Russian Army may like the MT-LB’s performance in the marshy terrain of Leningrad oblast. At any rate, it’s a simple, reliable armored vehicle that the MOD still has in large numbers.
The 138th IMRB’s tank battalion is outfitted with 41 T-72B3 tanks, ten tanks in each of four tank companies.
The brigade’s two SP howitzer battalions are organized in traditional fashion – 18 152-mm 2S3 Akatsiya systems in three batteries of two platoons with three guns each. The MLRS battalion with 18 122-mm BM-21 Grad systems is similar with three batteries, two platoons of three vehicles.
The brigade’s anti-tank battalion has two batteries of six towed 100-mm MT-12 Rapira guns and six 9P149 Shturm-S ATGMs. The batteries have two firing platoons with three weapons. The anti-tank guns are towed by MT-LBs, and the ATGMs are mounted on MT-LBs.
The brigade SAM battalion has three launch batteries of four 9K332M Tor-M2 SAMs. It has a battery with two launch platoons of three 9A34 Strela-10 SAMs, and probably a battery (two three-vehicle platoons) of older remaining 2S6 (9K22) Tunguska gun-missile systems.
