I agree with much of what you say, but I do take issue with the idea that "what makes you good at being an elite soldier makes you really bad at being a companion to other humans that aren't also an elite special forces soldier." Certainly the time required to develop and maintain elite fighting skills takes away from the time one could spend on personal and familial relationships, but there's nothing intrinsic to the makeup of an elite soldier that detracts from one's ability to relate to other people. I have a family member who is retired from a special forces unit with all that entails (lots of deployments, medals, injuries, lost comrades, etc.) who is a good husband and father, patient, calm, resourceful and helpful, and generally the kind of guy you'd like to have as a neighbor. I think he had some advantages that many special ops guys don't always have such as very strong family ties throughout his deployments and not getting married until after his deployments were over, but he's certainly not the only one from his unit to do well in retirement.
