Description

The BT-7A (F-32) is a rank II Soviet light tank with a battle rating of 3.7 (AB) and 4.0 (RB/SB). It was introduced during Update 1.89 "Imperial_Navy" as one of the rewards for Operation H.E.A.T. It uses the same chassis as the BT-7 and as such posses the same armor, engine and crew layout but adds a new turret fitted with the F-32 76mm gun.

The BT-7 (F-32) is a fast tank with thin armour for its BR. It should be used to flank and spot enemy tanks, taking advantage of it's very high top speed. The armour is very well angled at certain points, however being as thin as it is, don't count on it to protect you very well; your speed can be your best defense, so move fast and try to zig-zag a bit to make yourself a more difficult target for tanks farther away (not too much though, or you'll bleed off too much speed).

The BT-7 (F-32) uses the Christie suspension of the BT-7. Closer to a race-car than a tank, this lightning on tracks is fun to drive, but not particularly easy. With its high top speed and lightweight, this tank will drift in turns. For maximum control in turns, reduce throttle beforehand and the only tip/nudge the turn-keys. It needs some time to get used to, however, it does prepare you for the T-34s break-turns. It is important to note that the tank as an impressive inertia when turning on the move, as such it will continue to turn after you released the command.

Off-road behaviour is good and the aforementioned drifts aren't as extreme as on city-roads. Top speed is not reduced as well, making the BT-7 (F-32) one of the fastest light tanks of its BR due to its very wide tracks. It has the best Power to Weight ratio when compared to the M24, Crusader Mk III, Sd.Kfz.234/2 and M5A1 but offers the second worst reverse speed behind the Crusader.

The crew compartment is very small and inhabited by the driver, a Loader and a Gunner. The turret crew opperate in a very small environnement as such it is very rare that only one of them would die from a shot. "Not getting shot at" is the best advice for the crew to survive.

The BT-7 (F-32)Tank's successor 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.

Usage in the battles

The BT-7 (F-32) is a light tank and should be played as such, try to suprise the enemy, take a shot before he can react and get to cover before his teammates sends you to the hangar.

Avoid rushing into a group of enemy head on and exposing yourself for too long instead prioritise flanking and "sneek peek" attacks.

Stay away from intense enemy fire and common AA such as the Wirbelwind and R3 T20 FA-HS who can easily shred through your paper thin armor.

Use your light tanks abilities to spot targets and help with teammates repairs.

Pros and cons

Pros:

• Very fast and nimble
• Excellent offroad capability
• Powerful engine and wide tracks make the BT-7 a good climber
• Excellent cannon with a good rate of fire and 150g explosive shell.
• Performs well even when uptiered
• Slighly better gun depression than other 76mm counterparts (-6° over -5°)

Cons:

• Exposed tracks and suspensions are prone to be damaged
• Very thin armor and packed crew expecialy for 3.0
• Pretty large and difficult to hide
• Difficult to drive with precision - can slew on turns and bounces a lot after braking.
• More flat un-angled areas than BT-5
• Vulnerable to heavy machine gun fire
• Sometimes stalls on turns on soft terrain

History

Development

The success of the BT light tanks in Soviet service prompted additional upgrades and other developmental projects done on the design to increase its service life. The development led to the final model of the BT light tank series, the BT-7. The tank differed from the older BT-5 tank with a welded hull, redesigned hull front, and a new engine in the Model 1935 version. The Model 1937 version of the BT-7 added a redesigned turret that featured sloping armour.

The BT-7 (F32) is a modification of the BT-7 Artillery model sometimes called BT-7A. The artillery model took the design of the T-26-4 turret fitted with a KT-28 short-barrelled howitzer and mounted a 76 mm (3 in) CT short-barrelled howitzer. Due to the extra weight of the turret the BT lost its ability to drive on the road wheels. 155 BT-7A model were created, 11 converted into command version and only a few were tested with a bigger 76 mm gun, the F-32 gun designed by the infamous Soviet Weapon designer, Vasily Grabin.

The tanks saw limited service during the early stages of Second World War, or “Great Patriotic War”. The last reported action of the vehicles was in the Kiev district and Moscow in 1941. The tanks were also reportedly used in Manchuria against the Japanese.
