There's a new command interface which you can access with U. You **have** to use this menu to control your troops.

U to access
E and Q to turn
Space and Control to control your height
~ tilde (next to 1) to make your troops run. This consumes stamina, which in turn lowers accuracy and discipline
You can select companies either by clicking on the units on screen, or by selecting them in the UI in the bottom left
Use your right mouse button to place, and orientate your units
Controlling your armies in this mode is much, much easier, and currently the only way to properly control your troops.


Furthermore, you have to use our new company system. You can access it in the pre battle menu, there's an option called "Change the troops deployment plan". Here you can add as many infantry, cavalry and artillery companies as you'd like. An artillery company has to be present for artillery guns to spawn.
