Gentlemen and Dear Ladies (I doubt there is any woman here), here is an example of normie musings
My Friend : Have a look at this what type of tank is it ? (shows me a pic of what seems a Russian self propelled artillery)
Me : That's not a tank that's a self-propelled gun
My Friend : But then why does it has tracks ? aren't guns supposed to be small
Me : Because it is SELF PROPELLED gun and no that's small arms, guns can be as big as we can imagine
My Friend : Can't we just call it a heavy tank
Me : NO, it is a self-propelled gun
