Control groups are a fundamental component of RTS games.
Control groups are used in order to limit the total number of orders you are required to give while also allowing for fast selection of units.
The standard for control groups in any RTS game is the Control Key and a number (Example Ctrl+1). By binding this you can now quickly select that group by pressing the 1 key.
There are two main uses for control keys in Wargame: AirLand Battle.
The first is for fast access to units. Units such as helicopters and artillery are used very specifically and require timing. Every single helicopter cluster should have its own key binding and all artillery should have a keybinding.
Unmicroed units such as infantry often do not require any keybindings at all.
Tank battlegroups will require keybindings. These are often moved and used as soon as a unit is within range of them.
For the vast majority of a battlefield control groups will not be necessary. Sometimes quick groups for your flanks may be necessary just to highlight what you have and quickly move to them in place of using a map.
