An aggressive CT smoke, that can be used to push forward in yard and get information and/or kills. Aim at the bottom of the small grey box and do a left click just before passing CT Red. It gives a one-way towards silo and can give a one-way towards the Ts. You can jump the box if you are super aggressive.
You can also add a grenade to mix to push the Ts even more.
