Exactly. Be safe and maybe see a little of Korea while you're at it. An interesting country to be sure.
Don't know about gun laws there, but if its anything like Japan, you'd be hard pressed to buy operable guns legally there.
If in Europe, i.e. Netherlands, Beligium and Germany, you would bring it over, register it, buy it there legally, register it and then apply to bring it home. It can be a long process i have been told, but possible.
For Asia type countries, I think the answer is NO.... While at Camp Humphries, Korea, I worked in the PMO (Provost Marshals' Office) Physical Security and inspected arms rooms, NO personal weapons I saw at all (and in europe I saw them often).
While I was stationed in Germany in the early 90s, it took at least 6 months for all the BATF paperwork to go through. Most people that wanted to bring a firearm back started the paperwork 9-12 months before their PCS/ETS date. I am sure that a lot has changed since then (trying to buy firearms in Europe).
when I was in Korea, I was told that the civilian gun laws preclude general ownership...you will see alot cool airsoft. I tried to bring one back but it was confiscated (this was in '94) now airsoft is all around but not at that time
