Toy Soldiers: Cold War

Another very simple achievement that can be earnt as early as Basic Training (level 1).

To do this, you need to get the Commando reward from a Barrage.

To do this, you need to max out your Turbo gauge. Jump on a machine gun turret, and get a 40 kill streak. This will earn you the barrage. It's random (with the exception of basic training) - once you've got the commando reward, press Y.

I had to kill a few things with the commando before it popped up.

Very easily earned during the tutorial levels of the game. The video below will aid you in knowing how this achievement is achieved.

Hope that the video was of some use.
