Okay first and foremost I want to make clear that i make this post with good intentions, and do not want to offend you elvis, but show you errors you did in my opinion to improve your game and hopefully your gaming experience in the futer.
Second I'm not a proffesional or trained military man, 9 month of duty just told me how to clean a weapon and my room . So my opinion is based on my gaming experience. I think i'm not at terrible player.
Third as I didn't played the battle I couldn't see the map as good as you could so there is a possibility that i saw oportunities and positions that in reality weren't there. You have to judge such things.
4. I'm german and we tend to say things more directly as you may be used to, so again this is written with good intentions, if I sound unpolite I appologize.
I think your purchase was okay, as it was intended to show of stuff. So I start with your plan for this battle.
Imho I had 3 major Points which I disliked a lot from the start of the battle.
1. your ambush defence of gelb with a platoon + mines deep in the forest.
2. your armor placment all the way back at rot
3. your incredible overpowered and imho useless defence of Rot.
So Point 1:
You didn't need to defend there at all. you would have gained nothing from defending that area. the critical area was the road. And even more importaint the bridge and the start of the road. would you have setup that forces there they would have had much more impact and slowed Bill down more. in the worst case Bill would have evaded into the thick forest where you wanted to defend. But that would have been great for you. It takes incredible long to get infantrie through such terrain. I think it would have been likley that the battle would have been decided before such forces would have reached gelb. and even if they would reach it they would have to cross a long distance over open terrain to reach rot. So in short as long as you control the road and the open terrain all forces going through those woods on gelb are out of the battle.
Second Point (2): this one isn't as clear to me as 1, But i belive that you put yourself at a disadvantage placing your armor so far behind your defence line. It was almost impossible for them to help at the bridge and the road behind it. They were also your most mobile and powerfull fire power and you needed to achiev more with them than just killing bills tank. i think you should have used them in your earley game with ambushes and harrasing. Sure that would be a risky move but there were a lot of ambush and retreat positions for them that you didn't use at all. I hoped to see them in ambush positions to fire on every road crossing that bill would have to make and than falling back to the next one. The Panther plus scouts (good scouts by the way) on the west side would have been enough to scare bill away from using that aproach. leaving 2 Hetzers for ambushes and harrasing. And If you wouldn't have defended that forrest at gelb you would have had the infantry to support and spot for them.
Let's get to Point 3:
Well you just robbed your platoons from a lot of theire firepower to put that MGs in positions where they would enter the fight when the battle was lost.
I don't recall how many support weapons you hold back there. 3-5 MGs(including the one from Gelb). That is serious fire power that you despretley needed at Blau and imho to cover the main road up north, and some forrest roads and road crossings. MG 42s are the main firepower of german infantrie and you just placed them where they would never have any use other than in a last stand where Bill would have secured everything else lost all his tanks and had no artillery left. That would have been the only scenario where those crucial weapons would have had a major effect. in almost all other cases they would have been more or less useless. One had effect but only because you abandond Blau and lost the battle.
Planing over let's get to execution.
Well you did a lot better than I expected you to do. But on the other hand you could have done even better. Bill's aproach was favoruble for you and you didn't made enough of it.
I disliked your move forward with your tanks, which got them killed right away. Well as i read Bills side too It was clear to me what would happen, but you got over aggresiv with that move. In such a Situation It's not a good idea to close distance with german armor vs allied soviet armor. they are just faster more maneuverable and they want to get close to you. So in almost every scenario you do not want to get closer to them. in the best case you get into position and kill all of Bills armor in one minute if that does not happen he rushes in your side and behind you.
After don't getting shot's at Bills tanks for several rounds you should have repositioned instead of attacking.
Okay last Point that i will mention. Your earley and complete withdrawl from Blau. I think you were correct to abandon your starting positions and fall bak. But you ran to far. you needed to fight for Blau and that as hard as possible. That was the Open terrain where you had the best oportunities to catch Bill's troops in the open and get crossing fire on them. Just imagin what have happend if the flame thrower had a squad to cover him.
Blau was your major Killing zone and you gave it up to early. you saw how good you MG's where in this kind of terrein if you have had the ones you placed in Rot here Bill would have had to pay a much higher price. Also Blau was the only objective that was defendebal. Rot and Gelb where open to fire from direct Fire weapons and such you almost automaticly loos every firefight vs Bills Troops If he can attack organised (If he can build a base of fire vs those objectives). Blau shields a lot of Positions from Bills covering fire.
So I think this is enough stuff to think about.
I hope you understand what I mean and you got another perspective on the battle. If you feel offended than please just ignore this post.
If you think I am wrong that is also okay and I would like to enyourage you and eveybody else who thinks I am to explain to me why.
Closing I would like to say I didn't liked your plan but was very surprised how well you did with it and I loved this AAR and hope I will read more from you.
