This one happens to be SMG specific, but for every design that makes excellent sense and meets the target it was made for, you get the ones where you want to go back in time and ask "what the hell were you thinking?"
Popped up in my mind after seeing a pic of a vz61 Skorpion on Facebook.
I'v never carried an SMG on duty, though I've shot quite a few and as a class i find them fascinating in how many designs can attempt to fill the same few roles.
Most military SMGs have done well, and make sense, i.e Thompson, Uzi, MP5, etc. Among the machine pistol crowd you get some more unusual stuff even today.. the ones that blur the lines have always made me scratch my head.
The Skorpion was, to the best of my knowledge built from the start to be a pilot/vehicle crew PDW, able to be worn like a pistol. Even in the 60s, body armor was becoming common. Yet somehow giving crews bailing out of a vehicle into a possibly nuclear Cold War battlefield full of 7.62mm rifle armed infantry, with limited ammo a FULL AUTO micro SMG...chambered in .32 ACP.... made sense.
Even in a Communist country, there had to be some WTFs being said. How a full auto pocket pistol was supposed to be better than a Tokarev, or even a Stechkin, or another serious caliber piece just boggles the mind.
One reason the AKSU appears to have gained prominence in later years..
