The first two are about my grandfather's division from WWII, the US 90th Infantry.

The next link is many PDF's and some scans of actual General Orders, AAR's, and Corps documents mostly from June 6th to the end of the war. Also it appears that alot of the 1942-pre-D-Day General Orders are available too. http://www.90thdivisionassoc.org/afteractionreports/frames/reportsframeunit.htm
The last link is to a site that has some interesting articles about WWII written after the war, including a copy of the US War Department's "Handbook on the German Military Forces" and an article of examples of tanks used in night combat in Europe, as well as one about artillery practices of the major combatants. http://etloh.8m.com/strategy.html
Hopes this is useful for some.
