Tommy's Trotters: UK, green uniforms and First World War helmets
Garlic Grunts: France, dark blue uniforms and army caps.
Sow-A-Krauts: Imperial Germany, grey uniforms and Pickelhaube.
Uncle Ham's Hogs: USA, light blue uniforms and cowboy hats.
Piggystroika: USSR, red uniforms and Ushanka.
Sushi Swine: Imperial Japan, yellow uniforms and tropical visor caps.

Final Death: If during a mission one of your hogs are killed, on the post-mission screen their picture will be bruised and beaten, but they remain in your squad. If however three of your squad members are killed in battle, then one of them will be permanently deceased, which means losing all your precious promotions for that soldier as well (something which the player is usually unprepared for). If four squad members are killed in battle, two are permanently deceased.
Gang Up on the Human: The final campaign mission consists of 5 computer controlled teams (the ones you didn't pick and Team Lard) all sending their best troops to kill you. They never go after each other, though it is justified in that you've more or less taken over the world.
Gluttonous Pig: The main premise of the game is that massive armies of pigs fight a bloody war for a continent full of swill.
Messy Pig: In the comic book included with the game, an early panel depicts a family of pigs at home before they have joined the army; the living room floor is covered with small piles of excrement. A later panel depicts the pigs about to parachute behind enemy lines; one of them says that he needs to use the toilet, but the sergeant says "You don't use the toilet! You're a pig! You do it on the floor and roll around in it! We all do!"
Most of the various pig soldiers are either parodies of specific national stereotypes or Expies of famous characters of that nation from either history or popular culture, including seemingly half the cast of Star Trek.
The victory fanfare is a debatable example, depending on the interpretation: the first notes deliberately have a very bittersweet feel to them, in order to sum up the pointlessness of war in musical form.
