Guy, guys.
I should remind everyone that we are only at 1940.
Many of the famous developments in World War 2 are years away.
If your nation specializes in a certain thing I can understand
But also keep in mind there's no war currently going on which forces nations to upgrade their weapons as much as possible.
Almost any cannon over or near 100mm must be a howitzer or a warship-mounted battery.
Armored vehicles still need better engines so that they could ever begin mounting bigger guns and armor. They are practically APCs by the typical standard.
Assault rifles and the need for intermediate cartridge doesn't even begin to be developed until years later and it enters by the war's end.
Rockets are workable but it takes some years before they scale them down effectively for a bazooka.
Anti-tank explosives were just seen use. Delivery systems are in the works.
Jet engines are somewhat in development but they eat fuel like crazy.
Propeller airplanes were far from reaching their zenith. 250 mph was considered decent while 300+ mph was fairly impressive.
Fighters only equipped machineguns and heavy MGs since escalation didn't require them to carry anything else.
And I could go on.
Basically I think a few technologies we have is actually a wee bit too OP.
Of course it's up to the GM to decide but I mentioned the above examples exactly because some nations did violate them.
As far as things are, nobody should feel the need to up arm themselves this much, neither have the technology to support it.
I admit, I may be also guilty on a few of these but I'll scale down some things if required.
Anyways, I only posted this to raise awareness to the issue.
The rest are in the GM's hands.
