Relient is not a synonym for majority, moreover I was talking about aircraft in specific. Now you show me a chart that documents numbers of aircraft flown by the US airforce and country of origin that shows 1/2 of the planes flown were made in France and I will then agree that a majority of planes flown by the americans were of French origins.
Now, for the AEF. The US declared war April 6, 1917. Exactly how long do you think it would take to ship heavy weapons from continental USA to a state of battle readiness on the front lines. It took 6 months to build up for desert storm with modern logistics and heavylift jet transports and the US was not fielding an army of a million men like they did in WW I.
So yes, american men could get to the front quick, and for them to be of use, they needed local weapons at first. I am sure they supplied the majority of certain weapons classes such as tanks for which the French were technologically ahead. But I think if you looked at the ‘IPC’ value of the supplied, it was nowhere near the ‘majority’ of materials. Moreover, the allies requested ‘MEN’, fresh meat. By this time there were lots of heavy weapons in the field for the allies, they just needed more men for the meat grinder. So, when the request is for men, don’t hold it against the party for fulfilling the request. :-)
