Pretending that we do pay troops by the hour can be a useful tool for military leaders. Far too many leaders come at any problem with the assumption that labor is free. We regularly use highly specialized and trained people to do menial tasks. We keep people at work, often doing nothing at all, just to make others who actually have things to do feel as though everyone’s suffering equally. We keep absurd numbers of people at unit “duties,” even though technology has greatly reduced the need to do so. Keeping people around doesn’t cost a unit anything, so why not do it?
