K the German doctrine is next. Sadly couldn't get as much information about it as Grand Battleplan, but enough to see how the doctrines stack up in the earlier phases of the game.
Mobile Warfare Doctrine
1. Mobile Warfare: All Armor: Breakthrough +20%, Army: Army speed +10%, Organization loss when moving -10%, Planning speed +50%, Enables Unexpected Thrust
2. Delay: Army: +10 Organization, Enables Delay (Crossover to Superior Firepower Doctrine)
3. Elastic Defence: Army: +10 Organization, Enables Elastic Defence
Mobile Infantry (branch)
4. NA
5. Mass Motorization: All Infantry/Motorized Infantry/Mechanized Infantry: +10 Organization
6. Mechanized Offensive: Motorized Infantry/Mechanized Infantry/Armor : +15 Organization, Enables Blitz (Crossover to Superior Firepower and Grand Battleplan Doctrines)
Blitzkrieg (branch)
4. Armored Spearhead: All Armor: +20% Breakthrough, +15 Organization, Enables Blitz
5. Schwerpunkt: All Armor: Recovery Rate +10%, +10 Organization
6. Blitzkrieg: Motorized Infantry/Mechanized Infantry: +5 Organization, All Armor: Recovery Rate +10%, +10 Organization, Enables Breakthrough
Mobile Warfare (trunk)
7. Kampfgruppe: Army: Recovery Rate + 20%, +10 Organization, Planning speed +20%, Enables Overwhelming Fire
Sadly this is all I've gotten for this doctrine. The expected German path of going down the Blitzkrieg branch is full of serious organization buffs especially to armour and enables a lot more combat tactics than GBPD. By the 7th doctrine an astonishing +70% planning speed will allow the users of this doctrine to react very rapidly to the situation unfolding, while still keeping up planning bonuses, something the unwieldy GBPD wouldn't be able to do. The Organization buffs are massive and already by the 7th doctrine even the common infantry division, which is definitely not the focus of this doctrine has 10 more organization than when GBPD has been fully filled out. Building lots of light tanks (early on) as Germany should be a strong strategy so as to benefit as much as possible from the strong bonuses armour receives with the blitzkrieg branch. Sadly I don't know the first doctrine in the Mobile Infantry branch but the two discovered give huge bonuses in organization to mobile infantry, making it an interesting option for a country that can motorise most or all of its infantry (Belgium/Netherlands/France/UK/USA etc.).
