[Client Values; Actual values in
Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

BT-7 artillery

annoR105_BT_7A.png

The BT-7 artillery is a Soviet tier 3 premium light tank.

In 1934–1935 the design bureau of the Kharkiv Locomotive Factory developed this artillery modification of the BT-7. The new elliptical turret was equipped with the 76.2-mm CT-28 gun. In addition, some vehicles received new radio stations. A total of 155 artillery BT-7s were manufactured. The vehicles saw combat on the Karelian Isthmus, in Manchuria, and during the first period of the Great Patriotic War.

This tank was given out as a Gift Tank to anyone logging into the game between August 12-19 2015 for NA or August 12-17 for ASIA and EU as part of Wargaming's 5th World of Tanks anniversary celebration. The BT-7 art. is much like the BT-7. Although not as fast, it more than makes up for this with its 76mm howitzer. It is capable of one-shotting most tier II tanks, devastating tier III tanks, and can still damage tier IV and V tanks when using HE. It can use AP rounds but HE has better penetration and damage values. With poor view range and poor hull traverse when going full speed, it isn't very good at active or passive scouting. But the BT-7 art. can derp ambush enemy tanks like the T67, and the rate of fire isn't very bad.

Player Opinion

Pros and Cons

Pros:


  • Amazing acceleration with 37.04 hp/t;agile.
  • Great damage per shot and best DPM of all tier 3 lights
  • Good maneuverability
  • HE shells can penetrate most of its opponents(especially at the same tier)
  • High shell arc


Cons:


  • Horrible view range
  • Shells travel rather slowly
  • Armor is vulnerable to even HE shells
  • Poor accuracy on the move and during turret rotation, long aim time; Can not mount vertical stabiliser
  • Slow traverse speed while moving


Performance

While the BT-7A has good speed, it has very thin armor. Only the Pz. I C can bounce on it(with little angling), but on other hand, this tank has good alpha and reload time for a howitzer. The elevation is good but the depression makes aiming at low-height vehicles like the Hetzer more difficult in close-quarter combat, which due to the Howitzer's accuracy is essential. Knowing your enemies in tier IV and V matches is useful since the potential damage of the howitzer starts varying significantly between vehicles in these tiers - for instance it can easily destroy an Alecto but struggles against the heavily-armoured Matilda.

It plays best as flanker, possibly with guerrilla (pop out, shoot at tank rears then take cover) tactics, or as a SPG hunter later on in the battle. During flanking, exposure to the enemy can be minimized by peeping out via the front of the tank. This vehicle follows a similar playstyle for many of the other vehicles with howitzers in different nations (E.g. British and German tank destroyers) - generally thin armor, decreased rate of fire and high-damage gun to similar-tier vehicles.

Historical Info

In parallel with the main modification, 154 BT-7A artillery tanks were produced between 1936 and 1938. These were fitted with a larger turret and a 76 mm KT-type gun with 50 rounds of ammunition (40 in a tank with a portable radio).


In 1938, four experimental BT-8 tanks mounted with V-2 diesel engines were produced. After comparative tests of the BT-7 and BT-8, the diesel tanks were put into production in 1940 (under the designation BT-7M) with the power plants being produced in a separate plant of the Voroshilovets factory to ensure supply. From December 1939, the BT-7A went into production with some minor modifications - additional bracing for rigidity, a floor hatch, and a smaller air filter. The diesel tanks were more fuel efficient, and the petrol-powered tanks were soon placed into reserve.
