What laws do military pharmacies follow?

I have a prescription from a C-2 medication and am in a different state than where it was prescribed with no chance of returning for the next few months. Texas (where I am at) will not accept any c-2 scripts from out of state due to their own laws. I have Tricare and can go on a base to get my prescription filled. That being said I was curious, do military installation (being federal land) follow state regulations when it comes to pharmacology? I know things like state gun laws, legal alcohol limits ect. are not governed by state laws when on base even though the latter is pretty universal. I was hoping to find out before I drove to a post hoping it would just work out. Oh and the script is from a civilian Dr. not military.
