This video is simply meant to show how the in game AI is programmed to handle this virtual battlefield.
I am in the TC (Tank Commander) position, just watching how the script AI and mission script work. I give no orders, just watch.
This and similar videos are not meant to be exciting and entertaining, more for the person thinking about buying the game, able to see how the game engine works, and don't work. In this example the AI is good, it gets the job done, but not great, frequently turning it's thin side to the enemy, or running over it's own men.

BTW, the light key is simply L.... It says Control L in the print out sheet, and I tried Control L, Alt L, Shift L... never thought to try just L. lol
