Description

The BT-7 TD is a gift rank I Soviet light tank with a battle rating of 1.3 (AB/RB/SB). It was introduced during Update "Hot Tracks" as reward for watching Enlisted streams on Twitch.tv. The BT-7 TD is identical to the BT-7 in every way except for the exclusive camouflage, of a BT tank during the battle of Moscow, similar to the one found on the T-26 (1st Gv.T.Br.).

Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.

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

Pros:

• Deadly firepower at its BR: high penetration of up to 70 mm, with the 29 g TNT it can frontally one-shot most tanks like Pz.II, Chi-Ha or M3 Stuart; its firepower is effective even in high tier battles, if aiming at the right spot
• One of the fastest tanks in the game, great acceleration and overall mobility makes it a nice point-capper, flanker and climber - can outrun the commonly seen M3 Stuart on road
• 3-4 second reload time is quick enough to destroy opponents it cannot one-shot, like Pz.IV C and LVT(A) series
• Adequate reverse speed of -10 km/h allows it to quickly retreat from danger when there is no time to turn around
• Small and low profile allows it to easily hide behind cover or bushes
• Winter camouflage comes as the standard camouflage, excellent on winter maps but may cause some issues in other climates

Cons:

• Poor survivability: non-existent armour on all sides plus the closely packed crew makes it vulnerable to autocannons (Pz.II, Flakpanzer I), heavy MG (M13 MGMC) and even solid shells
• Turret and hull traverse is rather slow, meaning it may not be able to keep track of fast targets- this is also a disadvantage in a close quarters duel, as other light tanks like M3 Stuart can turn way faster
• Although fast, it is still slower than the Sd.Kfz.234 series on road.
• Gun depression of only -6 degrees (worse than previous BT-5) means it cannot effectively fight in hills
• Fuel tanks and ammo are scattered inside and are prone to detonation upon being hit
