The decision to put your life on the line for your country is a big one. While American citizens are required to register for the draft - in a bizarre gendered tradition, only if they are male - they have not been required to actually come good on that hypothetical promise for some decades now. That means the decision is one that is made voluntarily, which is the essence of heroism: a sacrifice that a person did not have to make, but chose to, in order to serve a higher good than their own pleasure or glory.

Obviously, not everyone who joins the military comes at it from such a selfless beginning. Some just look on it as a good job. Others desire to learn skills or build a resume that will help them market themselves in the wider job market later on. Still, others are looking to the GI bill to help them pay for college. However, all of these folks, once they are serving, will invariably pick up a particular pride in their unit and in the mission that the American military performs all over the world.
