It’s tough being the little guy on the block, especially when the guy picking on you looks like Drago from Rocky IV. Finland experienced a similar scenario in 1939 when the Soviet Union—partnering up with our favorite bad guys, the Nazis—faked an attack on one of their own villages to give them an excuse to invade their smaller neighbor to the west. The Soviets came at the Finns with an army of 19 divisions; the Finns could field only nine. But Finland also had something the Soviets didn’t: the Suomi KP/-31.
Where you’ve seen it:
Go figure, most films showcasing this chunky submachine gun are Finnish in origin, and pretty obscure as a result. The film The Winter War (right), shows the Suomi in use several times, if you’re willing to read some subtitles.
