One of the cool features in the new game engine is the possibility to have the computer opponent to withdraw its forces towards a destination.
From the manual:
"Withdraw Zones are a single tile that the AI Group will face towards. For example, a vehicle given a Withdraw Zone will reverse towards the Movement Zone, while keeping its front pointed towards the Withdraw Zone."
As seen above, for vehicles is a simple outcome that the scenario designer should expect. However, for infantry, there are some nuances.
Not that I am complaining, note the prodigious and tactically helpful amount of smoke thrown out by the withdrawing infantry, but I will have to recall this post while designing my scenarios.
