They work every day. Nine to five is out of the question. Weekends blend into the work week like any other day. they are constantly on alert, day and night, ready to attack any enemy that might have accidentally sauntered into their territory. There is no permanence in the place they rest their feet. The are always on the move, trudging through the thick, omnipresent sand. It's in the air, which consequentially ends up in their lungs, in their boots and plastered to their skin. Sometimes, they even eat it. They do patrols in 105 degree heat, completely covered in body armor. Patrols are not enjoyable during the day, however, utterly detested at night. Imagine; pitch black skies, (except the occasional moonlight), wild animals, poisonous insects and no telling what else.

Preparing consists of several classes to re-civilize themselves to the happenings that are still going on in every day life. The are reminded that there is green grass and running water. They might have a new baby or a new car. Whatever the reason, they pray that they can return to some sort of normalcy. They are thankful they are deemed noble as opposed to the "baby killer" of the Vietnam War. They hope that the erratic gun fire heard at any give time of the day or night doesn't make them jump at the sound of a balloon popping suddenly or make it difficult to enjoy a firework celebration.
As you sit back and enjoy the material things you have in life, realize that if it wasn't for the soldiers fighting for your freedom, none if it would be possible. The United States soldier doesn't do it for themselves. The do it for their country. They do it for our freedom.
