If you see that your teammates have a sticky bomb on them, you can shoot at it to knock it off of them, potentially saving their life.

Grumpy bomb is one of the best CCs in the game! Be sure to avoid it

Frontliners Tip Use your "CC reduction" card + "Resilience" to deny point pressure from "Grumpy Bomb". BK feels relatively safe you while stunned. "Jumping out" of stun earlier, works like surprise effect & confuses him.
