It costs the government several hundred dollars in pay and benefits to have each one of us standing around for a day, yet they were pinching pennies on ammo that cost maybe 10 cents a round.
This is pretty standard everywhere, not just in the military. To an accountant payroll is a fixed expense they have no control over (hiring and firing decisions are made by a different department). So they save on what they can control.
Also, there's often value to having people available to work, over and above the value of having them working right this moment. Firing people the first day there's no work for them to do (or even the first week, or the first month) isn't necessarily optimal.
So even if they had control over hiring and firing, they wouldn't necessarily want to change anything. In other words, it might be a legitimate fixed cost, not just something being treated as one by a bureaucratic mind.
Of course, it would be still better to use people maximally efficiently once they're hired.
In response to the question
I posted that my military experience seems effectively designed to increase executive function. Some examples of this from myself and metastable are
Uniforms- not having to think about your wardrobe, ever, saves a lot of time, mental effort, and money. Steve Jobs and President Obama are known for also using uniforms specifically for this purpose.
PT- Daily, routinized exercise. Done in a way that very few people are deciding what comes next.
-Maximum use of daylight hours
Med Group and Force Support-Minimized high-risk projects outside of workplace (paternalistic health care, insurance, and in many cases, housing and continuing education.)
After a moment's thought it occurred to me that there are some double-edged swords in Military Rationality as well, some of which lead to classic jokes like 'Military Intelligence is an oxymoron.'
Regulations- A select few 'experts' create policies which everyone else is required to follow at all times. Unfortunately these experts are never (never ever) encouraged to consider knock-on effects. Ugh.
Anybody else have insights on the military they want to share here? I feel a couple of good posts on increasing executive function might come out of a discussion on the rationalities and irrationalities of the armed forces.
