The RBT-5 is a gift rank I Soviet light tank with a battle rating of 1.3 (AB/RB/SB). It was available as a prize during the 2016 "Thunder League" eSports tournament as a giveaway prize for watching the Twitch stream, later every Dog-Tag owner who voted for Team Dislike earned one due to the "Champion" prize. It is currently available through the Gaijin store for individual sale or through the 'Project-X' trophy.

The RBT-5 is a regular BT-5 with the mounts to hold two 250 kg TT-250 torpedoes modified as rockets. The large calibre rockets prove hard to aim, but a real dealer to anything it hits.

This tank is quite unique. It has virtually no armour, weights only 11,5 tons and has a massive 400 HP engine (442 HP fully upgraded), giving it up to 38 HP/Ton ratio. This paired with excellent Christie suspension allows it to drive like a race car among tanks. Gun is an adequate 45mm 20-K cannon with decent penetration and quick reload.

Do remember - the RBT-5's two rockets are quite apart from each other, and that should be taken into account when aiming. The first rocket to be fired is the right one.

Usage in battles

The RBT-5 is really flexible when it comes to the usage, as it has great mobility and firepower, which is pretty much all you need for a good tank. Given its great 53 km/h top speed, it is good to use the BT-5 as a point-capping tank at the start of the match. It is better to travel on-road to fully utilise its speed to get to the point before the enemies do. Another good tactic is to manoeuvre to the flank of the frontline / point and attack from the side. Its speed makes it possible to go the furthest with the shortest time, surprising the enemies.

Once capped, the player can either quickly ambush behind a nearby cover waiting for the enemy to re-cap it, or just drive around the battlefield and help the teammates. Its 70 mm penetration and 29 g TNT will one-shot pretty much anything around its BR. If not, the 3 second reload allows it to finish them off easily. A sudden, close encounter is a hard test to the player's skills because the BT-5 isn't very good at turning as its tracks are quite long and narrow. Its turret traverse of around 11 deg/sec is certainly not the best. Thus those two factors can sometimes cause the death to the BT-5 so the player must respond fast and accurate.

Enemies worth noting:

  • Pz.IIs: Although not as fast as the BT-5, the Pz.IIs still have an average speed of around 40km/h. Also they are equipped with a deadly 20mm autocannon that will punch holes on the BT-5 with ease, and their rate of fire can quickly kill multiple crew. The BT-5 has thin armour protecting only 3 crew, making it extremely vulnerable to those autocannons.
  • Sd.Kfz.234 series: These wheeled vehicles all have scary on-road speed of more than 60 km/h, so in any map with roads connecting to the points they can always get there first and set up an ambush. However, these vehicles are wheeled meaning they cannot turn in place, they are rather sluggish when trying to turn, and they have either slow turret traverse or no turret at all so the player can use this to their advantage. Wiggle / circle around them to avoid their guns and force then to turn, then aim carefully and immobile them. Note that the DT machine gun on the BT-5 only has 10 mm penetration at most, making it almost impossible to go through their armour and kill any crew, so don't think of destroying these wheeled tanks with the MG.
  • M8 Greyhound, M3 Stuarts: These vehicles are equally fast, and the M8 can outrun the BT-5 if it's travelling on road, allowing them to get to the point before the BT-5 does. Therefore if America is on the other side the player might want to change their tactic and not to rush the point since low tier battles are always filled with fast tanks. The M8 has a roof-mounted .50 cal MG which easily tears the BT-5's armour apart and kills the crew inside. Also most of them have a vertical stabiliser that works at low speed, so avoid firing on the move with them.
  • B1 bis: A heavily armoured tank for its BR, but do not panic when you see it. Don't fire at a distance unless you are directly aiming at its side armour. The best option is to try and get as close to it as possible (point-blank range is ideal) and shoot straight at its side. However sometimes due to a variety of reasons the player might be unable to flank it and has to face it frontally. If that is the case, shoot the rather vertical driver's compartment and there's a great chance of penetration, killing the driver and the commander (which is also the gunner for the turret). Or, shoot between the two guns on the turret to kill the commander / gunner. Or, shoot at the near-vertical part of the curved gun mantlet of the big gun.

Pros and cons


  • 45mm 20-K gun offers great penetration
  • 20-K gun offers a good rate of fire
  • The BR-240 APHEBC rounds deals the best damage and spalling at its rank, allowing for impressive post-penetration damage
  • One of the fastest tanks in the game, the best acceleration and overall mobility
  • Front armour, although very thin, may bounce shells thanks to the decent sloping of the glacis
  • Sometimes used in high rank matches as scout/distraction/intruder - spawning does not account to a total of 3 spawns
  • Excellent turning radius, allows the vehicle exploit enemy vehicles' turret traverse speed
  • Very powerful rockets, can even instantly destroy a Maus, allowing the RBT-5 to handle even formidable foes


  • Equipped with only 2 rockets
  • Rockets are set at a fixed angle which further complicates aiming, does not allow for zeroing targets
  • Armour can only cope with rifle caliber rounds, could also deflect a few heavy machine gun rounds
  • Very vulnerable to quick-firing automatic cannons like the German 20mm cannons or the TShN
  • Terrible crew arrangement, a well-placed, penetrating shot will automatically take out the crew
  • Rockets may overshoot at close range, due to the affixed nature of the mounting



The BT, or Bystrokhodny tank, was the forerunner to the T-34. The tank's name translates to "high-speed tank" and it lived up to that expectation. The BT series of tank's origin lays with an American Racing enthusiast named Walter Christie, also a prolific automotive designer. When the U.S. Army Ordnance Bureau repeatedly declined to produce Christie's designs, he becomes so frustrated with them for turning their interests away from a tracked vehicle able to go 60 miles per hour, so he turned to other countries such as Great Britain, Poland, and the Soviet Union. The Soviet's were eager to purchase his designs and were able to receive two M1931 turret-less examples that were labeled as "agricultural tractors", as well as the license to build more of their own variants. The Soviets quickly produced working prototypes of Christie's tanks and made various changes and improvements at the KhPZ factory in Kharkov. The development of the Christie suspension on the tank would become the BT-2 light tank. Further development would improve the BT-2 design as the BT-5, released sometime in 1935.


The Christie design was based on the concept of "convertible tanks" which was to reduce the wear of tank tracks as they were quite unreliable at the time. The tracks could be removed and instead the vehicle would run on a chain drive to allow the tank to reach high-speed on roads with just the wheels that could be steered by pivoting the front road wheels. The conversion took about 30 minutes to complete. The Soviets saw the "convertible tank" feature of the Christie design to be of little use due to the lack of paved road in the Soviet Union, which was necessary for the use of the wheel conversion. The conversion also added unnecessary complexity and weight, so this was removed from later Soviet tank designs.

The primary changes from the BT-2 to the BT-5 was its new larger cylindrical shaped turret and more powerful 45 mm 20-K cannon. The new turret was capable of housing radio equipment and gave crew more freedom to move around. The BT-5 was slightly heavier then the BT-2, but the armour was left unchanged. The 12 cylinder M5 power-plant that was based off an American Liberty aircraft engine that was adapted for use with the BT series. It allowed the tank to travel up to impressive speeds. Several variants of the BT-5 were constructed that included features such as flamethrowers, 76.2mm cannon, and a snorkel to aid in fording waterways. Projects in extending the BT's role in other jobs also took place, such as the RBT-5, which is a rocket launcher artillery variant that mounts two large 420 mm tank torpedoes on the turret, but this did not past prototypes. During its development, it was also slowly replaced by the improved BT-7 model being produced form 1935 onward. A reported 1,884 BT-5 light tanks were produced from 1932 to 1941.

Combat usage

The BT tanks were meant to be a cavalry tank, and at the time of their introduction they were considered some of the finest tanks against other countries' tanks. They had great mobility of all available tanks, and its 45 mm gun could perform very well in combat. The only drawbacks of the design was its light armour and its gasoline engine, which caused the design to be rather flammable to improvised incendiary weapons. The BT-5's most notable combat service came against the Japanese at Khalkhin Gol. The tactics of Soviet Marshal Georgi Zhukov and the performance of his BT-5 and BT-7 tanks led to a decisive victory. It was during this battle that the BT tendency to catch fire was found, but its performance was positive against the inferior Japanese armoured forces.

During the Spanish civil war, a force of BT-5s fought with the Republican forces and performed quite well against its inferior German and Italian opponents, whom deployed lightly armoured tanks with machine guns as their armament. With the outbreak of World War II, the BT-5 was deployed against Poland and aided in the defense of Russia from the invading German army in Operation Barbarossa, though was of little use against the better German Panzer IIIs and Panzer IVs. The BT-5 saw service through to the end of the war, where it participated alongside BT-7s and more modern Soviet tanks against Japanese-controlled Manchuria in August 1945.
