I'm thinking of joining the reserves. I believe I qualify to go in as an e-3 for training I have completed. How does that affect getting promoted. I read: "Army -- 24 months active duty, 6 months as an E-3, and commander's recommendation" to be promoted to e-4. Would I still have to wait all that time to get promoted? Also whats it like being a vehicle/ heavy duty mechanic etc; for the army, I'm already a semi-truck/car mechanic.
Thanks just curious of what I'm getting myself into.
