Ok so I am a moron. But my understanding when it comes to large scale warfare is, uniform. Sure, you need things in the ww2 time period like smgs for sup fire and support to my teams. But one thing bugs me... I am a stupid mid west gal. I grew up shooting pop cans with a BB gun and my Grandpa soon had me shooting crows with a 22. So I gotta ask and its bugged me forever and Google is no help. Why break from the m1 or even the Thompson and mix in a new ammo batch in the .22? I understand for say a para, who needs light weight but my research shows the .22 rifle spread from air to land to even sea. Yes, the Garland was the main stay and the Thompson a sub rank for specialists or noncoms. So why have the .22? You have boys with BARS and 30 calls. Mix in the m1 and Thompson and NOW we need another crate of ammo type in a lower cal and weaker round in the .22? I'm not being a bitch here I am honestly wondering why? Please dont troll I'd love a honest historical answer why a squirrel gun is on the front lines?
