[Solved] Are detachments considered formations when taking assessment tests
There is no requirement that retreating units fall back towards their own forces? Can you retreat in any direction, as long as you stay 900 yards away from enemies?
Correct, the Formation must attempt to maintain a 900 yard gap between it and all enemy. Generally speaking, this means it ends up going back towards its own lines, but it is situation specific how broad of options it has.
