Turns out Ki-XX is not pronounced "Kay-Eye", but like it's written - "Kee" (but much shorter). It's Japanese for saying, Type XX (the words itself literally means, 'machine').
As for Junkers and Jumo, they're pronounced Yoonkers and Yoomo, respectively. I'm sure many of you guys knew that already, but I've heard it mispronounced on vox many times. Hell, I had it wrong up until recently. It's funny because you can go the longest time in an online community and never actually speak those words (except in your mind when you type it out), so you never get a chance to get corrected by anyone.
