Smoke Grenade Launcher is the key to winning Breakthrough on Defense

Ive been trying out this gadget after ignoring it thinking it is meaningless but I think any defense team that doesnt have 4-5 smoke grenade launchers on it (especially on exposure) is going to have a much harder time.

Using the smoke launcher on the hill at the first sector makes it impossible for attackers to break though that choke point, and also is useful to prevent flanks and tanks shooting at the point from a distance. 

its use is obviously important in the second sector where its a choke point in the mountain. Defenders can approach more safely and avoid being picked off at a distance at both points. 

I was surprised to win 3 defense games tonight when using the smoke launcher and encouraging the team to use it as well. 

If you havent tried this gadget, give it a shot and see how useful it is.. The line of smoke it leaves basically cuts off most areas of the game from players and if they push through they have no cover and are easy to pick off.
