The US soldiers take shelter from a heavy snowstorm in a house with a German half track in front of it. The rear of the half track has no roof. In the morning we see inside the rear of the vehicle, filled with guns and other equipment but absolutely no snow.
The Belgian woman is seen making WHITE flour bread: this is almost impossible as in war time Europe it was quite a luxury, found only on the black market in the big cities, or on the desks of high officials, and for certain not in the poor house in the middle of the Ardennes forest.
Early on, before the Malmedy massacre (which took place in December 1944), a German solder relieves Kendrick of two packs of Lucky Strikes in green packaging. In reality, Lucky Strikes switched to white packaging in 1942, alleging that the green dyes were needed for the war effort. Oberon, the British flier, correctly carries a white pack of Lucky Strikes.
The German POW is given a sweet wrapped in an aluminum foil, which he later uses to create a silver angel. Aluminum foils for food, like the white bread, was another luxury quite unlikely found in a forest dwelling in the Ardennes. During the war all the metal objects of common use were forcefully collected and taken out from the market to build weapons.

Corporal Deacon is seen taking out his bible from his left pocket and putting back in his left pocket several times throughout the movie but when Gould searches his body near the end it is retrieved from his right pocket
At the end of the film we see a German soldier fire a Panzerfaust (Anti-tank weapon) at a tent. The "bomb" launches like a rocket in a straight line and blows the tent to smithereens. This would not happen. The Panzerfaust is not a rocket launcher, it is effectively a big gun. There is a charge in the tube which explodes and "Lobs" the charge towards its target. It does not fly under its own power and certainly does not travel in a straight line. The shaped charge is encased in metal and the front needs to deform to set off the detonator. This would require striking a hard target such as a tank. If a panzerfaust was fired at a tent it would merely bounce off.
Two of the main characters are from the 101st Airborne Division, and were supposed to have been fighting on the Elsenborn Ridge, which is on the north edge of the Bulge. In fact, the 101st was a couple hundred miles to the rear on 16 December 1944, the day the German attack began, and was never near Elsenborn. The Malmady Massacre took place about 17 or 18 December 1944, long before the 101st got to Bastogne.
