Officers, as I mentioned, are much more likely to be satisfied with their jobs, and it may be related—actually, it is related—to their use of their skills. That is an important factor contributing to satisfaction with civilian employment. In terms of the army, combat arms in particular is the least transferrable in terms of skills. Those who leave at a fairly low rank, especially, are the least satisfied with their civilian employment.
The span is quite large. I don't have the numbers in front of me, but I think it was over 90% of all officers are satisfied with their jobs, but it was less than half for those who left as privates or cadets.
