I think what you're looking for are the
official U.S. army histories (aka the Green Books) put together after the war by the military itself. These are exhaustive accounts of every action carried out by U.S. military forces during the war. Canada has them as well, as do the UK, etc. They're basically the official record of the military, written and used by the military itself but also available to the public.
Here's an example from the volume on the Ardennes where a German officers input would have been helpful:
German military poverty was nowhere more apparent than in the stocks of ammunition and POL which had been laboriously amassed to support the attack. The Sixth Panzer Army artillery commander, for example, had pleaded for twelve to fifteen units of artillery ammunition for the first ten days of operations.24 On 16 December there were only one and a half units with the Army Group B guns and only two additional units in prospect. Although OB WEST appears to have estimated a daily POL consumption of 260,000 gallons per day for the Ardennes force, a number of the higher German quartermasters predicted that Army Group B would burn four times that amount on each day of the operation. 25 The armored divisions had in their vehicles and trains enough fuel for perhaps go to 100 miles of normal cruising, but battle in the Ardennes could hardly be considered normal travel. Though it is a commonplace that commanders and supply officers at the tactical level always want more shells and gasoline than they probably can use, there is no question but that the Ardennes counteroffensive began on a logistical shoestring.
These histories also reference the German unit diaries - day-to-day records that are kept by every modern military.
As far as I know, the Green Books are not available from normal retail outlets, but you can buy them direct from the site linked. They're also available for free in pdf and html format.
