which map ? ıf you talk about 100p map

light tanks + artilleries + Interceptors , tactical and attack bombers

dont try to upgrade factories at first days you dont need them
buy rare materials from trade market and concentrate to produce planes , what remains as resource use them to produce light tanks and artilleries
start with artillery until research tactical bomber
dont attack to AI countries before produce artillery , allow to other beginner players to invade them , they will clean everywhere for you with their infantries , you can get back provinces easily from them , allow to france to attack belgium and netherlands and allow to poland to attack czechoslavkia

for example you saw poland is trying to invade czechoslovakia with his infantries he succeed to capture 2 provinces and still fighting in this situation dont attack to czechoslavkia directly attack to poland with artilleries and march to warsaw you automatically got help from czech units

basically bomb and rush it is blitzkrieg you can stack your aa units with artilleries what you got at beginning of game you dont need another unit if your enemy is not 150 level most of them dont know how to play

Well, it is very hard to fail when you move swiftly. Your starting army is unmatched by anyone near you; use it to take over basically the land Hitler did in history. After that, you have a wide range of options; decide who/where looks weak is mostly the best: Asia, Africa, even America isn't impossible when there is a weak USA player.

ok I suppose you are not ally with noone lets look to neighbours
germany can fight against every country at the same time on this map , you should be quick to invade them one by one dont lose time with AI countries

- United Kingdom
firstly send away your navy west of norway or farther , UK navy is stronger than german navy at the beginning he can easily sink your navy and bomb to hamburg
keep to produce submarines from hamburg , upgrade level of submarines at next days , when you have enough submarines hunt them dont try to produce battleship or cruiser
ıf he is experienced player , he can produce strategic bombers to destroy your cities , always put some anti airs to your big cities at next days
when you invaded france you will have a lot of planes to start invade UK

- France
to destroy maginot line you need a lot of artilleries , you should produce artilleries like crazy , send your all artilleries , anti tanks and anti airs to france border when you have 8-10 artilleries start to destroy maginot line
bomb his fortifications with artilleries and attack to his convoys with planes which ones come to fortifications to help
after this continue to production with planes , tactical and attack bombers , you have already enough tanks and infantries as a main army you need artilleries and planes

- Poland
ıf you allow him one day to stay alive he can produce a lot of anti air , anti tank , artillery , ınterceptor to defend border you should invade him at first day while you keeping to produce artilleries for france you dont need to use artillery for poland send all of them to france your medium tanks and infantries are enough to invade poland ıf you have problem while fighting you can use your planes to help them ıf you dont want to lose medium tank to reveal enemy anti tanks send ınterceptor first to look province

- Italy , Yugoslavia
ok you produce submarines , planes , artilleries and invading france and poland now I guess you have enough artillery and planes to fight everyone at the same time put 1-2 defensive units to austria mountains ıf they send tank or similar thing to attack there bomb them with planes ıf they try to send big armies with aa stack pull back your artilleries from france border after destroyed maginot line and destroy italian stack after invaded france and poland send your planes to italian and yugoslavian front after them go to UK

In terms of alliances allying with the UK is not a bad option to prevent infinite wars.

If the US is a good player he could supply you with a lot of resources and build a big economy.

Use MT or HT instead of LT and don’t focus on your Air Force. Your economy is going to wear out fast.

I personally is too lazy to build any troops in Germany 1939 so I just kill France and Britain on the first day with the starting armies. Then I go inactive because I am bored

Yeah, this map is particularly harsh with the sleeping sickness for the major powers. Rounds are often won by a coalition of countries like Brazil, Tibet, and Canada.
