Groups and formations can really help to organsie our troops efficiently. They also enable us to issue orders to multiple units.
Let's create a group now. We can left-click and drag a box around our units, or hold down the Control key and select units one by one.
With our units selected, we'll press the "G" key or click the Group button, to set up the group.
We can now issue orders to our group and place it in one of several formations.With our group locked in our chosen formation,
they'll now attempt to hold their shape and spacing whilst carrying out move orders.
