Book excerpt: The all-volunteer army served the country as professional soldiers for reasons of patriotism or adventure or even economics, since monthly pay of twenty-one dollars was to some men better than nothing and better than charity. Many men reenlisted time and time again. Whether a private was stationed in Texas or New Jersey for his three-year hitch, he first had basic training, the length of which varied according to how long it took each soldier to master the fundamental skills of the infantryman. If an enlisted man grew tired of the disciplined life where he had no responsibility except to follow basic orders, he could purchase an honorable discharge. If he couldn't come up with the cash from his twenty-one dollar pay envelope or winnings from poker or dice, he could go AWOL and after ninety days the army would simply remove the soldier from the rolls with a court-martial in absentia and a dishonorable discharge.
