For reasons unbeknownst to them, a hundred US military personnel from 2016 have been thrown backwards in time, coming out in the middle of Kansas, December 9, 1941, one day after the Pearl Harbor attack. They can find no particular pattern among them except they're all officers (commissioned and noncommissioned) or specialists, with none of them being grunts. They further are all either decorated or otherwise distinguished from their peers, and span the Navy, Marines, Army, and Air Force. None have any particularly meaningful expertise outside their military careers (none are electromechanical engineers, none designed weapons previously, none are manufacturing geniuses, etc, etc).
They can't figure out why they went back in time. For some more concerning is that their memories have been altered. They no longer have any specific knowledge of the events of WWII, with their knowledge of history becoming less and less spotty the closer to 2016 they try to recall. While they realize that the allies most likely won the war (since the allies are still around for the most part in 2016 and the members of the axis didn't seem to fare as well; they even recall Berlin being divided in two by the US and Russia), they don't know the actual mechanics and events, and so they can't act as prophets for the battles to come.
They reach out to the US Government and somehow manage to convince the powers-that-be that they are, in fact, from the future. The US military forms a small task force to allow these 100 men to advise the military as to ways to improve their military by means of tactics, organization, training, strategy, and logistics.
To clarify: none of these men are engineers, and so they can't help design modern technology unless the technology is simple enough for the normal man to understand. These men probably won't be useful in even so much as (for example) speeding up the development of the jet fighter, unless it's arguing the case as to why the jet fighter is a good idea, and to describe what roughly a modern jet fighter looks and acts like. Nobody is going to have these men make blueprints.
Since the 100 men know the US emerged victorious, they're not aiming to help the US win, but to:
- Reduce the casualties in WWII
- Speed up the victory of WWII
- Leave the American public sector in a more favorable place
- For traditional warfare (They think they remember a "Korean war" coming up, although they can't remember the exact date or any real details)
- For non-traditional warfare, specifically the Cold War
They also are wise enough realize that not all modern tactics, strategy, etc, will be a good fit for the past. Some things won't apply, some things will need to be altered, and some things will be smart ideas for the military to implement right away.
As long as they can provide a solid (enough) argument for any suggestion the US military has expressed willingness to cooperate as far as the US public will allow.
Oh, and the 100 are considered top secret, and knowledge of them is to be kept absolutely secret from both the world at large, and the citizens of the US.
How would these 100 men help accomplish the before listed goals? What knowledge might they possess that could be helpful? How would their efforts affect World War II and the coming Cold War?
