The manufacturer of the Humvee is not cool with all the references to its vehicles in Call of Dutygames, according to a lawsuit it filed against developer Activision.

AM General, the company that makes Humvees, filed a lawsuit against Activision Blizzard for referencing and replicating its vehicles in the Call of Duty series without permission, Reutersreported Wednesday.

According to Reuters, AM General accused Activision Blizzard taking advantage of the prominent name and status of the brand Humvee, also known as HMMWV, which stands for High Mobility Multipurpose Wheeled Vehicle. Humvees have most commonly been used by the U.S. military since AM General started production on the vehicles in the mid-'80s.

Numerous Call of Dutygames have featured or referenced Humvees since Call of Duty 4: Modern Warfare. The vehicles are key features in some scenes and situations in multiple games, and are seen in Call of Duty-related material outside of the games as well, including guides, promotional material, toys, and books.

According to Reuters, AM General said the series' success over the years came "only at the expense of AM General and consumers who are deceived into believing that AM General licenses the games or is somehow connected with or involved in the creation of the games."

Although the Humvee trademark probably isn't actually the reason for the Call of Duty series' success over the decades, as AM General claims it is, AM General still has the right to protect its trademarks.

AM General is calling for punitive damages, meaning it wants compensation for the use of its trademarks and additional money to punish Activision Blizzard.

Activision did not respond to request for comment, and the company has previously stated that it does not comment on current lawsuits.
