The name of this level is a reference to the video game series Medal of Honor.
The St. Capitulons mission has various references:
Upon entering the church, Homer will sometimes say that he prefers "Castle Smurfenstein", possibly a reference to the computer game Castle Wolfenstein. The interior of the church resembles the decor of Wolfenstein 3D, an FPS predecessor of Doom.
During the first part of the level, one of the villagers of Saint Capitulons alludes to having met Jean-Paul Sartre and talking about a state of mind known as Being and Nothingness while clearly not caring much about what he had to say, alluding to the real life French Existentialist as well as his philosophical tract Being and Nothingness. Coincidentally, Sartre had operated within the French Resistance to some degree during World War II in real life.
One of the quotes by the Frenchmen, "I have surrendered, therefore I am!", is a paraphrase of the quote "Cogito ergo sum" (which literally means "I think, therefore I am!") by the mathematician and philosopher Rene Descartes.
Jerry Lewis is briefly mentioned by the French villagers. Similarly, Pepe le Pew was mentioned as one of France's greatest and most celebrated lovers, and there was a reference to calling a general strike.
In the briefing for the Africa escort mission, Sergeant Abe Simpson mentions a storage depot in Algeria called Jabba Al-Hutt, an obvious reference to Jabba the Hutt from Star Wars.
When completing the Africa level, Private Burns, when covering himself after letting slip that he intends to sell the paintings for "a really nice car", says he intends to give them to a museum, alluding to something Indiana Jones says in his films.
Some of Smithers' quotes in the final level references various aspects of the World War II era, including the Japanese Internment Camps, the development of the nuclear bomb, and the Andrews Sisters. He also makes a brief reference to the concept of fragging from the Vietnam War.
The ending has Homer referencing getting beer via a fake license in America.
The trophy Bart collects in this level is the movie "Saving Krusty's Privates", a parody of Saving Private Ryan.
There are some differences in each version.
French people carry flags only in the Xbox 360 and PS3 versions.
In the PS2 and Wii versions, there are only two areas: the city and the ship. Africa is only in the Xbox 360 and PS3 versions.
In the PS2 and Wii versions, you just have to get to Burns' platform to complete the level. In the Xbox 360 and PS3 versions, you have to defeat him.
Strangely, in the France part the French people will attack you even though you are trying to save them.
In the background of the first level, people can be heard yelling "We shall surrender like we've never surrendered before!" and "I have surrendered, therefore I am!". They are presumably Cheese-eating surrender monkeys.
The fight against Private Burns in the Xbox 360/PS3 versions resembles that of the final battle with Liquid Ocelot in Metal Gear Solid 4: Guns of the Patriots. It isn't a true reference, however, as the game was released a year before Guns of the Patriots.
