I'd say wireless radio and the submarine. I know that the earliest version of the radio was more like a "radio telephone." During WWI there were people who had to run the wire connecting each unit. I also know that as far back as the Revolutionary war, Washington oversaw a trial of a very early version of the sub. But the true sub was developed before WWI, with the nuclear sub being developed in the 1950's.

marconi invented the radio. and also you forget the ta-312, and ta-1 and these are still used! we used them in afghanistan back in 2004. the first modern sub used was in the civil war.

on that note. still used and unchanged is the mechanical diesel injection pump invented by robert bosch and used in ww1 on the unterboats.
