@Viracocha:
I was just debating if a “opportunity shot” should be implemented, that is, when and attacker or defender opts to retreat, the opposing forces get one round of attack without suffering return fire. I like the idea that pulling out does carry consequences, forces are always more exposed during a retreat.
Retreats always carry consequenses. If you retreat from a 1 IPC territory, then you lose 1 IPC income. If you retreat from a 5 IPC territory with VC, factory, Airbase and Naval Base, then even bigger consequens to you.
As for the playability and game balance. Remember that if the defender retreat, and the attacker got a Leader, the attacking motorized units may follow up with a Breakthrough combat move into next enemy territory for a second battle. Now when he comes to think about it, the defender may be better of with a Last stand battle in the first territory. The Defenders retreat and the Attackers Blitzkrieg rules got its own inherent mechanic and balance.
As for the link to the real world. Its correct that retreating forces are more exposed than dug-in forces. But the most exposed force of them all is the attacking force. And you never see the defenders taking a free shot at the attackers, now do you ? Tactical retreats is an art. You cover the retreat with smoke and minefields, and perhaps some suppressing artillery fire that always come in handy, or move in the dark at night, from one camuflaged foxhole to the next. Attacks, on the other hand, now that is some messy thing. Men with fixed bayonetts running into the mg-fire, with no place to hide. You know it takes 1000 bullets to kill a dug-in defender, but only 1 to kill an exposed attacker ?
