Tachanka (Defender)

Tachanka is a 3 armor, 1 speed defending operator who was released with the base game. His special ability/gadget is his Mounted LMG that he is able to place down and shoot. Once placed down, anyone in the match can use it: so watch out for attackers trying to get a cheeky kill. Tachanka is great for locking down a point of entry and making it difficult for the attackers to advance.
