When a German solder is wounded and falls to the ground, then crushed face down by a retreating German tank, the shots show two helmets by his head on the ground, then one helmet. Of the six total shots showing this memorable effect, the second helmet is missing in three of them.
When the troops are entering the city of Carentan, they're being attacked by a German MG42 from a window and so fire back. During this exchange, bullet-holes appear and disappear on the advertisement-sign attached to the house.
It is suggested that Albert Blithe was shot in the neck by a sniper, and the credits title card states that he died of his wounds in 1948. Fellow Easy Company soldiers had believed this to be true because they never saw him again at any reunions (they missed the first one due to still being in Europe). After the mini-series was broadcast, relatives of Albert Blithe came forward with information and documentation that Blithe was wounded in the right shoulder, recovered from his wounds, attended the 1st Annual Reunion of the 101st Airborne Division Association, and subsequently went on to have an outstanding Army career (including over 600 parachute jumps). Blithe spent the rest of the war in Army hospitals and wasn't discharged until October of 1945; during the Korean War he was part of the 187th Airborne Regimental Combat Team and was awarded a Bronze Star and a Silver Star for jumping behind enemy lines. Blithe actually died in 1967 while on active duty in Germany, and was buried in Arlington National Cemetery with full military honors. At the time of his death Blithe held the rank of Master Sergeant and had been awarded three Purple Hearts, three Bronze Stars and a Silver Star.

There is no evidence that the Gebirgsjäger, or mountain rangers of the Wehrmacht or SS ever wore real or replica Edelweiss flowers as part of their uniform. While they did have to climb up to the peaks were Edelweiss grows and pick one as a sign of manhood and of being a true soldier, they wore a pin in the shape of the flower on the left side of their cap, or as a patch on their right sleeve.
While Sgt. Malarky is riding in the motorcycle sidecar, the airborne patch on his cap is sewn on the wrong side.
