War is an ugly thing. This is especially true if there are those who are not convinced by the leaders of their side. They move to the other side and then proceed to fight under their flag. Sometimes, without even knowing what they fight for.

Traitors are born not because they find some meaning in the other side. Rather, they are just not contented with the way their side treats them. They join the other side for the wrong reasons and then, when they find out that the other side isn't that different, they try to switch back. They turn their back on their world flag and what it stands for. They fight under a new flag. Often, they fight in different ways. They develop weapons, they use espionage, and they may even be strategists.

This sort of thing happened a lot before modern combat. However, the defectors were not hailed as traitors. Rather, they defected only after they have been defeated by the enemy because they deem the opponent more honorable than their old masters. They only fought under a new world flag if they felt that the ones who led under the flag were more honorable than the ones they served. These days, it doesn't happen that way. Combat is no longer based on a code of honor. Rather, defectors judge their actions based on personal gain. Their attitude toward their own country is so mercenary that they are in fact some of the worst kinds of combatants history has ever seen.
