The worse ones were Johnson's 100 Thousand, they were a danger to themselves and the rest of the unit.
Johnson’s 100,000 was followed by a congressional mandate called project 200,000. There were some real lowlifes among those who were just mentally below par. I went to a joint service school on an army base that had their quartermaster training to include the postal guys. The had classes in that school on how to properly wrap packages and some of them did not get it. Too many of them became cooks which was a real morale killer. When the Corps rotated us onto mess duty, many of us were better cooks than the assigned cooks. I had been a restaurant cook for 4 years so for me it was a mind numbing experience to have to watch those guys “cook” and take orders from them.
