So I'm and Oregon resident, but I'm stationed in Washington does that mean I can't or not supposed to bring my firearms into my state that I live in?
Sorry if my post above confused you. It's your gun. You can bring it with you wherever you travel to as long as it is legal for you to possess it at your destination. The fact that you are military has no bearing on that. If you were just Joe Smoe civilian either traveling to Washington on vacation or moving to Washington you could bring the gun with you. Although, except for very limited circumstances you could not take it to New York City because it is not legal for you to possess it there without the license. Washington State and 95% of the United States is fine.
What is illegal is for you to ACQUIRE a gun from an out of state source and bring it to your state of residence. Retrieving YOUR gun, that you have already legally acquired, from a storage location to bring with you is just fine.
What is a very gray area in the law is the fact that you left your gun with someone else who is now transporting your gun, without your presence, across state lines. That appears to be in violation of 18 USC 922(a)(3). It would seem like they are violating that section by taking the gun with them to their home state, because they ACQUIRED the gun from you, an out of state source, and there is no "loaning" exception to 18 USC 922(a)(3). In other words, it's OK for you to loan the gun to someone who is not a same state resident, but as soon as they carry that gun back into their home state, they have violated the law.
Hope that clears it up. Also, as deadin pointed out, your military orders to Washington State, plus you active duty military ID card make you, for the purposes of all firearms transactions, a resident of the state of Washington, that is Federal law. In Washington, you do not have to switch your driver's license, but you can take your orders and ID card to the Washington Department of Licensing and get yourself a Washington State photo ID, which will make purchasing firearms in WA from FFL's much easier. AND if you get your Washington CPL, it does away with the waiting period for handgun purchases. Also, without the CPL (or one honored by WA) you cannot carry your handgun loaded in your vehicle - rifles are shotguns cannot be carried loaded in vehicles with or without the CPL.
