Actually we used fire bombs, not napalm. Same as the Brits used on Dresden, basically. Oh, and it was the United States Army Air Force, specifically XVI Bomber Command, headed by "Bomb 'em back into the stone age",Curtiss LeMay. LeMay said that in the context of Vietnam, BTW, not WW-II. It caused the same sort of hand-wringing that we hear about this precision strike on a military target by the IDF.
Actually Fire bombs is a more modern term for napalm. That is what the Ordinance Shop web site says. Note the last paragraph.
And just for the record there was no such thing as the Army Air Force. Their was the United States Army Air Corp.
The terms United States Air Force and United States Air Forces were used along with the Army Air Corp. to refer to air power possessed by the United States.
It was quite common back then to refer to British Air Forces as well as American Air forces or United States Air Forces.
It was also used to describe Japanese air power as in "Planes from the Japanese Air Force attacked Pearl Harbor."
