Could i get mobilized in the reserved ?

Yes you can still be deployed if you just Enlisted in the Reserve's. In any Military Branch/contract you can be deployed. That's the entire purpose of the Military. Did you know that the whole purpose of the Reserve's, is so the Government dont have to pay it's Troops full time, and they are still highly trained? All the reserve's do is keep you up to date and keep you well trained, in case your number comes up for a deployment.
