Well, as above: Johan is nerfing Sweden now, so no worries
Also: 4th biggest air-force when the war was over, and a few years forward. It takes alot of Industi to build up that. Sweden was OP at that time except for manpower (army around 500K, I belive during the war...), but no war means no chanse to prove it was the case...
The highest number mobilized at one time that I can find at the moment seem to have been 320 000 men. During a few weeks after the german invasion of Norway and Denmark, that was almost everything that could be mobilized.
In 1941 Sweden had 10 "Fördelningar" of roughly 20 000 men each (Divisions for the rest of the world), along with 1 infantry regiment on Gotland.
8. Motorized brigade was formed in 1941 from the cavalry brigade (Reformed to the 8. Tank brigade in 1943).
7. Motorized brigade was formed in 1943
9. & 10. Tank brigades was formed in 1943
Along with all above the artillery, engineers, anti aircraft and some other branches of the army formed some war time units.
The homeguard of some 90000 men was also formed during the early parts of the war.
It was almost ten years after the war that Sweden had the fourth largest airforce in the world in 1957.
