Call of Duty is a popular video game series known for its realistic depictions of military conflicts. While the games are often inspired by real historical events and settings, they are not based on specific true stories.
Most of the Western Front locations presented in the first two Call of Duty games and the more recent Call of Duty: WWII are quite accurate, especially France. The names of the towns, villages, and even the operations are well-researched (as they should be) and even recreated with decent attention to detail.
