One common theme is the dehumanization of soldiers. In military dystopian novels, soldiers are often turned into mere tools for war. For example, in 'Starship Troopers', the troopers are trained to be highly efficient killing machines with little regard for individual emotions. Another theme is the corrupt nature of military power. Military forces in these novels often use their power for self - serving or oppressive purposes. In 'The Forever War', the military bureaucracy seems more concerned with its own continuation and expansion rather than the well - being of the soldiers or the society at large. And finally, the theme of the futility of war. These novels often show that war in a dystopian military setting is never - ending and doesn't really lead to any positive outcomes for the people involved.
Common themes include the loss of freedom. Military dystopian novels usually depict a world where the military has excessive control, restricting the freedom of civilians. In '1984', the military - like Thought Police monitor and limit people's thoughts and actions. Another theme is the breakdown of society. Military actions and power struggles can lead to the destruction of social structures. For instance, in 'Hunger Games', the Capitol's military dominance has led to a fractured society where the districts are oppressed. Also, the theme of moral ambiguity is present. Soldiers in these novels may be forced to do things that go against their own morals in the name of military duty, like in 'Ender's Game' where Ender unknowingly commits genocide in the name of military victory.
