Very easy achievement, can't be missed.
As soon as you start the game, go to single player campaign and start the tutorial. For the Tutorial you have to use Kaiser Willhelm.
The achievement unlocks while the level is starting.
I used the tutorial to connect it with the "Power up" achievement
But you can do it on whatever level you like to do it on.
Hope this helps.
Any improvements? Please let me know in the comments below
