The BT-7 is a Soviet tier 3 light tank.
The BT-7 was a further modernization of the BT series, with a total of 5,556 vehicles of different variants produced from 1935 through 1940.
The BT-7 is a direct upgrade of the BT-2, offering even more speed and acceleration, more HP, and much better turning properties. It is one of the fastest tanks in the game, in exchange for very poor armor and relatively weak armament.
The BT-7 leads to the A-20.

Player Opinion

Pros and Cons

Pros:


  • Excellent speed and ridiculous acceleration
  • Great maneuverability
  • Low profile and good camouflage values
  • ZiS-19 gun has good accuracy when on the move
  • Surprisingly good for ramming


Cons:


  • Paper-thin armor and below average HP.
  • Disappointing damage and penetration on all weapons
  • Bad view range for a scout, passive scouting is even against tier 5 not really an option


Performance

The BT-7 is basically a slightly faster BT-2 with slightly more HP that now faces up to tanks up to Tier 5. It has a choice of three weapons, all of which are carried over from the BT-2. The 23 mm VYa has decent damage output and is particularly good for running-and-gunning while on the move, but is useless against most Tier 4 and Tier 5 tanks. The 45 mm 20K has mediocre accuracy, fairly good penetration, and good damage. The 37 mm ZiS-19 offers the best penetration of all the weapons, and has excellent accuracy but somewhat disappointing damage output.
The BT-7 excels as a raider/breakthrough exploitation tank, the role for which it was originally designed. Once it has broken through the enemy's front line, it can hunt down enemy artillery and, in skilled hands, cause a great amount of disruption and can own basically any tank tier 4 and below. The BT-7 works particularly well in combination with other BT tanks.
While adequate enough to allow the BT-7 to act as a battle tank in Tier 3 or 4 matches, all the weapons have insufficient penetration to deal with heavier tanks that the BT-7 sometimes faces in Tier 5. In such matches, the BT-7 is best used as a support sniper or flanker, not drawing any unnecessary attention to itself. While the BT-7 is quite capable of pulling off the circling technique against heavier tanks and tank destroyers, this should only be used against isolated enemies and with an experienced driver.
The BT-7's great speed and good camouflage also allows it to be used in the scouting role. Its superb speed will allow it to take up forward spotting positions quickly after the start of the game. However, the BT-7's view range is merely ok, though this can be remedied to an extent with the use of Binoculars, Coated Optics, and the Recon or Situational Awareness skills. The BT-7 can also be used as a counter-scout, as it has the speed and sufficient agility and firepower to intercept most enemy light tanks without too much trouble.
In addition, the blistering speed combined with rather decent mass allow ramming to be a somewhat viable option for this tank. But unless your driver has the Controlled Impact skill, this should only be done if your tank has low health, and against serious threats which have a small enough mass to take serious damage from a collision.

Crew Skills

  • Camouflage as the first skill on all the crew members is a good choice and is invaluable if the BT-7 is required to take up the scouting role. Repairs is not very useful, as getting tracked or having the engine damaged on the BT-7 without a repair kit is almost always fatal.
  • A more specialized set of first skills would be Situational Awareness (Commander/Radio Operator), Snap Shot (Gunner/Loader), Smooth Ride (Driver). Situational Awareness provides a bigger view range bonus than Recon, and is generally superior. Snap Shot and Smooth Ride combined act like a Vertical Stabilizer (which the BT-7 does not have access to), reducing the accuracy penalties incurred while moving and rotating the turret. Due to its speed, the BT-7 has higher accuracy penalties while moving than most tanks, and this can be important in helping the BT-7 get its shot off first. Off-Road Driving is also a viable option for the driver to further augment the BT-7's excellent mobility.
  • Upon reaching 100% on the first skills, dropping the commander's skill for Sixth Sense is an excellent option. Deadeye is a good perk for the gunner, especially when targeting weakspots like engines and ammunition racks. The gunner also acts as the loader, but the loader only has access to perks which are not particularly useful for the BT-7: Safe Stowage increases the HP of the ammunition rack, but the BT-7's best defence is to not take a hit at all, while the BT-7 will very rarely find itself at under 10% of its HP so that the Adrenaline Rush perk activates.
  • Brothers-in-Arms is a good perk to have on any tank, but requires all crew members to have it at 100% before it works. The bonus to crew skills is particularly noticeable when combined with Improved Ventilation.


Early Research

  • All the BT-7's guns carry over from the BT-2, but the 37 mm ZiS-19 needs the conical turret. Both the 23 mm VYa and 45 mm 20K are viable on the BT-7, depending on the preferred playstyle.
  • The 12LL radio can be researched on the SU-26, and should be mounted if available.
  • The first priority should be the M-17F engine, which dramatically increases the BT-7's performance.
  • The BT-7 suspension should be researched next for increased hull traverse speed and load limit
  • The BT-7 conical turret should be researched next, finally allowing the ZiS-19 to be mounted.
  • Finally, the V-2 engine is required to unlock the A-20, but it is inadvisable to equip it; it provides 20 hp less than the M-17F and also weighs 140 kg more, significantly reducing performance. The only benefit it has over the M-17F is a 5% less chance of catching fire when hit.

Historical Info

The BT-7 was the last of the BT tank series of Soviet cavalry tanks that were produced in large numbers between 1935 and 1940. They were lightly armored, but reasonably well-armed for their time, and had much better mobility than other contemporary tank designs. The BT tanks were known by the nickname Betka from the acronym, or its diminutive Betushka. BT (Russian: БТ) stands for fast tank (Быстроходный танк, Bystrokhodny tank). The successor of the BT-7 Tank would be the famous T-34 medium tank, introduced in 1940, which would replace all of the Soviet fast tanks, infantry tanks, and medium tanks then in service.
