The reality of Army life is very different. You want to peel a potato, that's your business. As far as basic training goes, yes, it's tough depending on the shape you're in when you start. Basic is designed to get you in the best possible physical shape in the shortest amount of time. But nobody is going to slap you around or even yell at you very much.
Advanced training makes the difference.
AIT helps you realize what you are capable of doing. It will likely show you how much more you can do than you even thought you could. And, this training could lead you to a successful career or business when you leave the Army. Often, these are regular jobs, like electrician, journalist, carpenter, accountant or computer jockey. You'll earn 30 days of paid vacation in your first year, and there's usually as much or more to do on the base as is in the civilian community.
