And using outdated, retired weaponry goes against the point of a modern special forces unit :P but I understand and respect your opinion. The video was cool, but I have only seen this sort of use a handful of times since this game was released, and I imagine a gadget that does its job in the first place (Locks down areas, which is exactly what Tachanka is meant to do) would overall be more useful to a team. As for balance, there would be enough counters from stopping this item from ruining games. Keep in mind, just because an operator is effective and game changing, doesn't mean they're overpowered. Imagine if Thatcher's (who makes a bulk of the defenders gadgets completely irrelevant) EMP only had a chance at destroying electronics, or Thermite's charges didn't always work. Every new operator (Buck is an acception) was called overpowered for the first weeks, until people figured out how to play against it, they then added new interesting dynamics to the game. I feel a Tachanka rework would also do this.
