- Accidentally Correct Writing:
- The multiplayer segment was mocked for allowing such historically inaccurate combinations as black German soldiers, but black people serving in the German military was accurate. While the Nazis saw black Africans as racially inferior and discriminated against them, they for the most part never passed racial policies explicitly targeting black people (If only because there weren't a lot of black people in Nazi Germany at the time), so they accepted black Germans (but only the men, obviously) into the Wehrmacht if they wanted to join up.
- With all the of the gaffes made with the weapons, it's almost inevitable that a few technically correct choices would seep through the cracks. The biggest example of this is the "Extended Magazine" attachment for the Springfield, M1 Garand and the Kar98K; for the Garand, an experimental variant dubbed the T20 was select-fire and used BAR magazines (and was essentially a precursor to the M14), while the Kar's magazine is based on an actual "trench magazine" for the older Gewehr 98, though that was fixed and held 20 rounds instead of just 7. The Springfield likewise had a 25-round magazine that was only used in certain branches and was technically removable, but in the same way the Lee-Enfield's magazine was intended to be removed (AKA only for cleaning).
- As the game's gone on, the various weapons added in straddle the line between this and Aluminium Christmas Trees. A lot of the weapons LOOK like they're near-fictional, but bar changes here and there, they all existed at some pointnote .
- The Danza: Fischer shares his surname with his voice actor, Jeff Fischer.
- Dueling Games: With Battlefield 1, which came out a year before and has a historical era throwback.
- Ink-Suit Actor: All of the characters with a speaking line are modeled on their voice actors.
- Recycled Premise:
- Most, if not all, of the missions featured in campaign, were already featured in the older Call of Duty games. Prominent examples include Aachen and The Bridge at Remagen which were already featured in 2004's Call of Duty: Finest Hour.
- The campaign's premise of focusing on soldiers from the 1st Infantry Division was actually covered by Spark Interactive and Treyarch 13 and 12 years earlier, with the aforementioned Finest Hour and Call of Duty 2: Big Red One in 2004 and 2005, respectively.
- Sequel Gap: In a Spiritual Successor sense; the franchise itself sees yearly releases, but the last Call of Duty game set in World War II was 2008's Call of Duty: World at War, nine years earlier.
