Argo44,
The rules for Active Duty Military are drastically different than those for Civilians(other than government employed civilians, which are somewhere between). The 68 Gun Control Act allowed active military to import 3( otherwise legal) guns with very little trouble, essentially with approval of "Military Customs". I did this from Viet Nam, and Germany. Later, as a Dept. of the Army Civilian, I was allowed to import them with an IRS form 6a, which was essentially an import permit, in my own name. A normal civilian must go through an authorized importer, who has to make a living. Of course, after my time in and around the military, things got screwed up by the Clinton and Obama administrations and some local Commanders put in place by these administrations.
