I'm enjoying the conversation here great Chris, so thanks for that...

I would though say that the Germans did employ some early "special forces" type units by developing their Stormtroopers in World War 1... Elite troops, hand-to-hand specialists, innovative and "think on their feet" type men... I think the allies were caught off-guard by those units when they were first deployed.
When I compared technological innovations though, I was looking for more broad impact type things... For instance, plastics were largely developed out of World War 2 and needs from the era, and so today we've got plastics in just about everything. Pretty broad innovation to come out of that war... However, air warfare in general and bombing were concepts out of World War 1... A pretty large impact on history considering today's use of smart bombs and things to actually try and "contain" warfare.
WW1 really gave birth to the concept of the aircraft carrier, and submarines... The two things that have basically taken naval warfare and changed it forever.
I think as war goes, WW1 did more to change how we fight wars than WW2 did, however I think WW2 actually gave more innovations in how we live our daily lives... Nuclear power, plastics, preservatives, etc. One could argue medical technologies advanced faster in WW2 as well, though I don't know much about that... I've read that Nazi experiements advanced medicine, but I really don't know much on that... The U.S. made some medical leaps in the era too I guess though, the proper ways, as well... Not an area I'm real familiar with however, just things I've heard or seen somewhere along the way.
A dream vaca for me would be touring WW1 & 2 battle sites in Europe I think... I'd love to do what you did, with just jumping in a car and checking out some of those areas. I had a teacher in high school who owned a home in France and went back every Summer till he retired and moved there. He was one of my history teachers, and sort of the guy that got me into WW1/WW2. He helped excavate a couple trenches, was part of a group that tried to help dispose of dud bombs and other explosives, etc. He has a pretty wide collection of artifacts too he showed me... It's amazing what you can find some places to this day!
I was on another site for the 1:18 military hobby, and I guess 3 Panzer tanks were just found in a field in Eastern Europe recently... I mean, that's pretty incredible stuff.
