I didn't say that. Long overseas deployments, however, may not be in the best interests of the child.
A similar issue is beginning to appear on the civilian side as well. Yuppie parents get divorced; one takes a job across the country. Courts are starting to give custody to the parent who stays in town as being less disruptive to the child.
You didn't have to say it: it's inherent in your argument that military service, if it involves deployment - which in today's world we must assume it does - is incongruent with having a family.
