Next up in the series of video updates introducing the unique features of Arma 2: Operation Arrowhead is the High Command tutorial video, which showcases one of this unique mil-sim's lesser-known - but exciting - gameplay features.

The walkthrough provides a sneak peek at the tutorial available in-game and demonstrates the simplicity of commanding larger groups of units; issuing direct orders, setting waypoints and conditions, and assigning the behaviour of groups of units. Getting to grips with the simple command interface is important, and doing so reveals an entirely distinct type of gameplay experience.
