Someone told me: In the 1st Iraq war, the American tanks could shoot a projectile further then Saddam's Russian tanks, so all the US tanks had to do was keep a good distance away from the Russian Tanks Someone told me: During the Afghanistan mujhadeen war against the USSR, there were SAMs

I was raised conservative, and all I ever heard was that our weapons were too “mean.” That we didn’t need to blow shit up that hard, but the defense industry wanted money, and that we went to war to make that money. And I believed it. And then Russia invaded Ukraine.

1. The first ‘special forces’ style mission from a submarine occurred in August 1915 WW1 when Lt. Guy D'Oyly-Hughes, Royal Navy, swam with a makeshift raft to blow up a Turkish coastal railway

First use of a submarine in war for sure. This is more relevant to SF missions, although he wasn't trained for that obviously, and was more in the tradition of RN officers doing daring deeds

Writing my book on American intel in WWI I ran across a 1918 document claiming that US Army intel personnel “work[ed] on submarine connections” between Italy and the Austrian island of Lissa bringing back documents from “Austrian official files.” Possibly true, but I doubt the subs were American.

2. D'Oyly-Hughes suffered a sad end when as a Captain, on 8 June 1940, he went down with his ship, the aircraft carrier HMS Glorious. Ungloriously, it is widely considered that his attempt to sail without adequate protection was ill advised. 1,533+ lives lost in the sinking

Fabulous effort with this thread! But there seems to be an error in this painting. I read your account of the Pearl Harbour raid. Those IJN mini subs had a hatch connected to their mothership sub so the crew could get on board while both subs were submerged. So no crew climbing while surfaced.
