It does sound silly, but the US Army/Navy are actually using these (slightly modified) controllers for machinery these days. Although, I don't believe they're using them to control submarines and the like.Traveling 12000 meters under the sea without any safety precautions and signing a waiver which states that they know and agree to ride on a non certified submarine. Yes that’s a whole other level.
I will also add its Controlled by a cheap video game controller…..
