How to do it? Show up with what do point-to-point pls
Research and equip ur divisions with logistics company already by around 1939.
The learning curve of hoi4 is: starting producing earlier, what u will need on the rest of the game, if u get beaten because of logistics, the restart and invest earlier in logistics.
Also pickup since from begin a Field Marshall with no Traits, or with the "brilliant strategist".
Use him in all wars(including spanish civil war), u will get the "organizer" trait for him(Field Marshall without traits, farm newer traits fast), then once u get "organizer", choose "Logistics Wizard" for him(-15% supply consumption).
By 1939 u can research logistics II, that improves logistics company supply reduction.
The heart of your production will be: infantry weapons, artilhery, support equipment, light panzer II. once u have filled then with at lest 10 factory each, then u start producing fighters and CAS by 1938.
If u feel rich u can also produce SPA. then ur light tank template will have SPA too.
This is the core to bulldoze SOV:
infantry equip+artilhery+support equip+light panzers+fighters+cas. Motorized is essencial also, but its cheaper, 5 factories dedicated to motorized could be enough.
Don't invest in bombers, or medium tanks, or any fancy stuff, u should flood the "core production".
Then u should have 240, 21 widht INF divisions by Jan 1941, all with logistics, 120 under the traited logistics wizard field marshall, that guy will be the "north field marshall", the other 120 will be the "south marshall".
U should have 48 light panzer divisions, 24 under gunderian, 24 under rommel, and manstein as their field marshall, use these guys to do the encirclements(i showed before) ur just put them in line with infantry(the just push play button style). Ur fighters will give the air superiority bonus(its improve tank speed) and the CAS will eat every resisting fighting.
The
Mobile Warfare doctrine stacks lots of
breakthrough, thats the poetic side of Hoi4: synergy, integration, coordination. U already have panzer generals, u have panzers, then u have panzer doctrines.. ur overproduced light panzer II equiped with
logistics will be unstopable.
The Mobile Warfare also stacks lots of org bonuses, its mean u get no punished if take some rest, to refresh and reorg troops, if its sucking at front because pushed too far, stop and let everyone get org again to restart atack. once u have overproduced equipment, its means their recover their strength too, in meantime u can build extra railroad to maintain supply always high.
Thats the "steamroller" playstyle, u just stack up benefits from a doctrine and focus production in what get that bonuses, u always will have advantages over enemy.
Beware of winter penalty, its hit hard now, u can't blitz on winter because all ur divisions will be too slow, either to move or to break a point(the fights take ages), the winter end around april/may every year.
