There are six different pig nations featured in "Hogs of War" that, while not directly named, are represented by their comical names, unique uniform colours, accents, and headgear. Each nation is parodied in the name of their squad and soldiers, as well as the pigs' dialogue during combat, usually at the start of each turn, before firing a weapon, after defeating an opponent, or upon their own death. Voice work is delivered in thick, over-the-top accents, with comical lines emphasizing the stereotypical nature of each represented nation, usually acting in an exaggerated manner (some portrayals of which were even held during both World Wars), or speaking about topics relevant to a stereotype, acting primarily as the game's source of humor. The six nations include the UK, France, Germany, the USA, Russia, and Japan.
