Correct pronunciation of AT-AT

So I’m watching LEGO Masters and they keep calling AT-ATs “at ats”. I’ve always called them “A-T-A-Ts”. This led me to google the correct way of saying it. I’ve seen that both ways can be correct but everyone says AT-ST the same way. How is this even a discussion? At At sounds so stupid. via /r/StarWars https://ift.tt/3eigy1G
