CT-side reveal HE on Dust2, thrown from CT mid into the T mid doors smoke. The grenade tears the smoke open for a moment and exposes anyone crossing mid or standing inside it.
When to use
Throw it as CT once the Ts have smoked mid doors and you hear the cross. The HE clears the smoke long enough for you or your AWPer to get a clean look at mid, plus free damage on everyone inside.
