If you see down bottom left faces, they are in your control
You would be F1 key then 1st guy in your group would be F2 and so on
Press eg: F2 then number buttons (can't rem offhand) but just try and you will see orders etc that you can give them, also off top of my head ...
Press F key for a man, then aim at an area and it will give a range readout, click and that man will go to that point
The key is the Funcion keys, once you figure it out it becomes second nature
Few keys for you, K=compass double tap k to keep comapss showing, 1 k tab and hold to see it
V to clamber over fences etc
T you can swap groups etc
Middle mouse button to call ammo artillery etc if you are equiped with them
F cycles your weapons
Just thought i'd throw them in the mix for you
