Smoke Grenades

Entry
Havng an engineer/medic on the side, that pops in view, and fires the underbarrel into the room, when you breach, can be very helpful.

Also when you procced down/up stairs, where frag grenades are hard to throw, you can smoke the stairs and go up, it will help. (If doing a 2x stair entry, try having both sides, use smoke grenades and take the upper floor)

Cover
It´s great for masking movement´s and providing inaccuracy for the enemy, if under fire in an open field.

Objectives
Great for taking and holding points, since they last for quite awhile


 * Generator in Bio Lab (very good to use smokes on)
