AKM rifles are used by the Taliban operating in Afghanistan. Cuban soldiers in Michael Malone's (Kevin P. Farley) documentary "Die, You American Pigs" are also armed with AKM rifles.
General George S. Patton (Kelsey Grammer) carries a Single Action Army revolver (likely a Cimarron reproduction) throughout the film, at one point contemplating shooting Michael Malone with it.
During a country western music concert to benefit American troops, Michael Malone sees the ghosts of Servicemen past watching over their modern counterparts. Only Malone can see the spirits of the soldiers and sailors from previous American conflicts, none of the other concert goers can see them. One of the first armed 'ghosts' he sees is a Vietnam era soldier, holding an M16A1 rifle - 5.56x45mm
During the same concert, Malone sees the ghosts of two World War I era troops are seen with M1903 Springfield rifles. One seems to have a transitional pattern M1903 and the second ghost soldier holds an Mk1.
Mauser Kar98k rifles were seen slung over the shoulders of German soldiers in 1938 when Michael Malone was thrown out of the window of the infamous 1938 Munich Agreement (where British Prime Minister Neville Chamberlain appeased Adolf Hitler and Nazi Germany) by General Patton. Two Kar98ks were see resting on a German tank during the 1938 Munich agreement scenes.
During the same concert, Malone sees the ghosts of two Union soldiers from the American Civil War, both carry the .577 Enfield Musket (which was commonly used to supplement the 58 Springfield musket that was the issued long gun of the "blue coats").
Revolutionary war solders are seen at the end armed with 1728 British Land Pattern Musket aka the venerable "Brown Bess". These are the earliest models with the brass end cap and extended lock shape.

When General Patton walks Malone down the street after the signing of the infamous Munich Agreement of 1938, (where British PM Chamberlain all but capitulated to Adolf Hitler's demands), the pair walks past a series of armored vehicles and trucks being loaded by German troops. Incredibly, and rather anachronistically, there is an ultra rare Imperial Japanese Type 95 Light Tank (called the "Ha-Go"), that was mostly seen in Manchuria. It sported a 37mm main gun and a 7.7mm machine gun. Why it is there in the background with an anachronistic German Iron Cross on the body is a good question.

Trivia
Inaccuracies regarding WW2 uniforms and conduct
Despite being a fantastical comedy / farce, the uniforms of the major dictators was unusual in that the color red was essentially 'de-saturated' from their clothing. Tojo's brown uniform was grey, and his red collar tabs were also grey. Hitler's Mustard brown coat also seem missing the red as well as the NSDAP arm band. Mussolini's arm patch would have red stripes, but it has grey ones. This 'could' have been an intentional choice to show that they are 'ghosts' of the past, but it is worth mentioning. As for the 'guards' or adjutants, German Heer or SS officers don't hold a posture like U.S. Marines, when at a meeting. When not 'at arms' (i.e. not wearing their belts and pistols or other military weapons) they would have their hats off and arms to the side.
