Reserves are awesome, but also suck. Try it out and don't be afraid to throw in the towel after a year if its not for you.
I think the VTU is underrated. The downside is you're doing
coloring books GMT and other important readiness tasks for no pay.
That is a seriously big buzzkill, think of it like a painful safety stand down + GMT day full of "everybody sign the roster for human trafficking, financial responsibility, don't haze people training, don't pick stupid computer passwords and don't put creepy Tina's CDROM in your work computer" back at the squadron. Take that and now make it groundhog day for two days a month. But-
The upside is it makes jumping back into the game
very easy- you have a CAC the whole time, you're plugged in to the reserve world by having full access to all the online systems, and as we've talked about on here so many times you won't get involuntarily mobilized (not unless you're the proverbial unicorn who speaks some obscure language fluently, has some obscure skill that is vital to some emergent threat to national security, and you have a TS). You can also get on funeral detail if you have an itch to scratch of contributing something meaningful to your country and to your military bothers and sisters (and funeral detail does pay).
If you're sitting on the fence then you can still do certain kinds of orders. You have to think of ADT orders and discretionary money as something meant to advance the mission in the reserves, it's not a jobs program for some schlep in the VTU at NOSC Pawtucket- although if that schlep happens to be a good fit to support the mission then you might be the guy who gets those orders.
If you're still sitting on the fence then you can run out the clock to 20 years too. Not that you'd actually do that but it's not like being IAP status where the clock is ticking for you to find a billet somewhere. If you're in the VTU then there's no rush to make up your mind.
