>For example the Hungarian military didn't adapted smgs because it was thought to be a weapon of policing force.

Same reason was used in post-war USSR, so there were no SMG development until 1990s. Official position was "police is the western opressive capitalist thing, we have people's militia and no big crime". For exceptional cases police used army weapons (i.e. AK, SKS, old SMGs from war etc).

When confronted with crime wave of late 80s, police used short AKS-74U as SMG replacement because there were no other choice. They use it even today, although some local made SMGs started to appear. It is pretty bad weapon for this role, because 5.45 bullets known for ricochet when used at short distance, and overall it is army weapon (designed for vehicle crews), not police.

But, if we'll go back to WW2 theme again: SMG wasn't really good weapon for mass army. For real army operation it has short range and not so good power, so it is ok only in close combat, but field battle isn't close combat for most time. Burst fire also isn't an option, it gives bad precision and uses ammo very fast. So, main weapon of infantry in WW2 was large and powerful rifle (and machineguns of course, but this is another story), although movies and folk stories give image of SMG as main weapon. Hungarian army didn't lose much.
