Usage in battles
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
Pros and cons
Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".
- More powerful engine, meaning it is much faster than the previous BT-7
- Fast-firing gun
- Sits at a higher BR than the previous BT-7
- Armour remains paper thin, with heavy machine guns and autocannons from SPAA being able to shred it
- Only 3 crew members
The BT-7M was an improved version of the Soviet BT-7 light tank developed before the Second World War. The main improvement was in terms of the powerplant, and at the time it was built no other tank in the world could reach the same speeds.
Development of a version of the BT-7 light tank began in the Soviet Union in 1938 with the construction of four prototypes at the Kharkov Locomotive Plant called the BT-8, which used a V12 diesel engine which was developed from the Hispano-Suiza 12Y aircraft engine. After the BT-8 was tested against the BT-7 it was determined to continue its development which resulted in the production version, designated BT-7M.
The BT-7M had the 500 horsepower V12 engine which was actually chosen partly due to greater fuel efficiency. The hull was reinforced with braces and some of the fuel storage was removed due to the higher fuel efficiency of the engine. The BT-7M’s engine also proved to be much safer in that it caught on fire much less often when hit by enemy fire. The BT-7M was proven to have a top speed of 62 km/h on tracks and 86 km/h with just wheels. Other than these changes, the BT-7M was fairly similar to the regular BT-7.
Production and Service
The BT-7M entered production in 1939, replacing all earlier BT-7 variants on production lines. It was the last BT-7 variant produced with production lasting until 1941. Approximately 788 BT-7M tanks were built during that time period, being superseded on production lines by the T-34 medium tank. The BT-7M did end up seeing some combat during the Great Patriotic War.
