Interesting, I used to go right and right in the Mobile Warfare doctrine as Germany, but I'm wondering about going left and then right. In your panzer army, how many divisions are motorised infantry and how many are tanks? Because I'm assuming as Germany you'll have some tanks to break through the enemy and then lots of motorised divisions to keep up and hold the line from counterattacks. So surely buffing those motorised divisions is worth it, because you'll have more of them than tank divisions, and they need to prevent you from getting counter-encircled?
You also get +20% breakthrough from Modern Blitzkrieg and plenty of recovery rate by going left and then right. So is getting the +20% breakthrough on tanks really necessary, do you think?
I don't utilize special tank and special motorized units. If I go with tanks (which I always do as Germany, but not too often with other countries), then I use one armoured template which looks something like this (width 30):
- 4 medium tanks
- 2 SPA
- 8 motorized
- engineer, AT, maintenance, recon, signal
As Germany I typically have ~60 infantry divs (width 40), 20 mountaineers (width 20), 2*24 armoured divs (width 30), 20 cavalry (6 cav, MP) for partisans, ~40 garrison divs to defend ports.
#breakthrough
I tend to do breakthroughs with my infantry (all have 4 line arty) and unleash the tanks one day later. This way the tanks preserve strength and org and let the infantry do the heavy fighting. I like my armour to be able to penetrate very deep into enemy territory which can be given up depending on the situation (rather encircle 100 divisions than grabbing and holding territory).
#why go right instead of left
Of course every sound panzer division will have more mot than armour, but:
1. there are more tanks in a tank battalion than trucks in a motorized battalion (IIRC)
2. Germany gets a lot of tank boost via ministers and such and combined with the right branch, you can create medium tanks that are as fast as motorized. I love speed more than anything and I'm only satisfied if my panzer/motorized divs can outrun any enemy. With the left branch your tanks will slow down the division. Building a division only consisting of tanks is bad because of low org.
