The change in some people was amazing. Some were showing improvement before they left basic training. Others took longer. Some people don't know about it, but there were programs were small time criminals were sent into the military. If they behaved during their time in service, their criminal records were expunged. Like I said above, they were given jobs they could handle. They were generally worked hard, so they didn't feel like starting a fight or going out to steal something after they got off duty.
