JTR:
Q. How does posession of firearms work when serving?
A. You must follow the laws of the state or country where you are stationed at. The best thing for you to do is contact the base where you plan on being stationed.
Q. I'll get moved around a lot I suppose. . . can I take my guns w/me, or do I have to find someplace to store them?
A. Yes, you will get moved around quite a bit.
You can take your firearms with you, however, if you get stationed in Kalifornication (or some other "occupied" state) you will either have to leave the "defined illegal" firarms somewhere else. You may be able to store the "defined illegal" firarms on base in the armory, as I said above, you need to check with the base where you are going to.
You may also need a "letter of permission" from the state. In the case of Kalifornication you will never ever be able to remove those "defined illegal" firarms for use outside of the base.
Q. If I can take them, what about Class 3 stuff at a base in a non-class three state?
A. Not gonna happen. When you move you are required by the ATF to inform them where your Class 3 stuff is going. There is no way that the ATF is going to give you a "permission slip" to move Class 3 firearms to a non-Class 3 state, unless you are a manufacturer.
Q. What about overseas?
A. Class 3 no way. Certain types of Non-Class 3 weapons may be transported out of the country. You might as well forget taking anything that starts with "semi-auto".
Q. Ok, where is my state of residency? (Currently OR).
A. Where ever you make it. You can change your record of residency at anytime (if you are Enlisted). Does Oregon have an income tax? If so, change your state of residency to Washington or Texas. You may have to prove that you are a resident, drivers liscense, vehicle registration, voter registration, home/land ownership.
Q. I have surpressors now, and will be getting a MG. What if I get stuck in some non-class 3 state?
A. Tell the ATF that you have them locked up in a safety deposit box at a bank in Oregon.
Q. Do I leave everything in a safe at a friends house or something?
A. You can't leave your Class 3 with a friend.
