The history of warfare goes back longer than we have records of history. People have always gotten into such extreme disagreements that they had to settle it by force. But at some point, city-states grew large enough that they could organize soldiers and form what was effectively a military. They may have had only melee weapons and horses initially and then chariots and spears, but as it grew as a concept, it became more organized. Eventually, nations realized some of these soldiers had more skill and knowledge than others and should be in charge of leading and training the other soldiers. If you proved your worth, you earned rank. The more knowledge, the more skill, the more accomplished you could be, the higher you would rise in the ranks. That's the theory, anyway.
Fast forward to the present and there are literally hundreds of ranks in militaries around the world. Each rank has a specific set of jobs that it entails, and that means each rank has its own unique flavor and personality. They're kind of like people that way. And just as different people excel at different ranks, those ranks really seem to fit people as well. We can tell you which rank fits your personality too, all you need to do is take the quiz!
