Oh, yeah, and I thought CA was bad... I am about to PCS to Germany and it is even more restrictive there as far as what guns you can bring. I guess I'll just have to wait until I come back CONUS to a gun friendly state before I build my firearm colleciton :-(
I used to shoot at the Deutsch/AmerikSchutzen e.V. in Grafenwoehr all the time. Still got the hat
I do my best to only get stationed in Free states so I can take my firearms with me. It is unfortunate that as free people would have to spend time reviewing laws of every locality where we may get assigned to avoid government prosecution for exercising a natural civil right.
You should contact the gaining Company Command Tm, thru your sponsor, and request specific information about your destined duty station. The guidance will vary between commands and should be structured from information the command will gain from the SJA (Army Lawyer Opine). Often, they would either advise you to secure them with a trusted person outside of that particular state until your assignment is over. Other times, you will be instructed to turn them in to your gaining unit's arms room immediately upon arriving. Although, I have learned of some horror stories of Soldiers arriving at the gate of their new duty station, U-Haul attached, and being asked, "Do you have any firearms with you today?" and they answered truthfully only to find themselves being detained and searched by LE.
Typically, you would be able to transport your POWs on your orders and IAW state laws for transport regarding separate locked containers for the weapon and ammunition, and in an area not readily accessable like a trunk or a towed trailer. However, with the new state laws being the way they are, I would advise you to just secure them with a trusted friend or relative outside the state in question. Either way, call ahead and find out from your gaining chain of command.
