Is there any research investigating the effect (or correlation) of a military background of a person on his productivity, effectiveness and other characteristics?

It is often casually claimed that a person with a military background is more disciplined, hardworking and so on, but it is interesting to find out whether it is has a scientific proof.

There some other supporting reasons like that Harvard accepts a lot of people with a military background or many of them succeed in the business world.
