Here are my reasons for putting such a forward defense in place:
1. Both the Dnepropetrovsk and Vitebsk factories were in danger of getting blocked from railing out this impulse, and I railed the wrong one. Minor mistake. I've figured out how to make sure the Dnepropetrovsk factory would be safe, but by then it was already done. So, I need the Vitebsk factory in the clear for another impulse.
2. This setup limits any attack on Pskov to a single river hexside.
3. The 5-4 INF can be put out of supply, and a Ground Strike would let it be overrun, but the only unit that can do that can't then get to a hex that would prevent the Vitebsk factory from railing out.
4. The 6-4 INF cannot be put out of supply, and while both it and the 5-4 could see a Breakthrough result, neither allows the factory to be threatened.
5. There is no way the Germans can attack the double-stack, even if both units are disorganized, and succeed. That's why the CAV is in the south. The double-stack is needed to make sure the 6-4 stays in supply and can't be overrun.
6. There are 4 units now vulnerable to attack on this front, but I doubt the Germans can get high odds on more than 2 of them. Well, maybe 3.
7. Even if the Germans manage to kill off all 4 frontline units, they've still gained only a hex or two on this front. With only 1 HQ in the area, and the front growing in length, this could become a problem for the Germans later in the turn.
8. Depending on how far back I retreated with these units, I'm willing to bet that 2-3 would be killed anyway. Isn't railing a factory and keeping the Germans from gaining 3-5 hexes worth an extra unit or 2 in the Destroyed Pool?

Feel free to disagree with any of this, but remember that only the units on the left of that dotted line are ones that I am "set on". Unless you prove me completely wrong. Then I'll become "un-set". [:)]
