OH YEAH! Trophy
In Campaign, Tactical Sprint through 5 Destructible wallsTactical Sprint is another new gameplay ability in CoD games. Basically it makes you run faster by pressing x2 and you can also destroy destructible walls with it. It's not a feature that you will use a lot through the game so the best way to earn this trophy if to farm the destructible wall that you can find on Mission 3: Stalingrad.
Right after getting the knife and killing the enemy with it when you get back home, you will see a destructible wall on your right with 2 soldiers behind it. Tactical Sprint to this wall to destroy it, it doesn't matter if you kill the soldiers or not, then reload the checkpoint and do that 5 times.
