I don't recommend garage storage as it will increase the possibility of moisture penetration due to temperature changes.
What is the storage time line? 1 year 3 years?
If 1 year then I would just thoroughly clean and oil them - put them in a gun sock - maybe even use desiccant or a dehumidifier in the case and call it good.
If 3 year then I'd consider using a storage grease instead of oil.
There are some new products for storage such as anti-corrosion storage bags Anti-Corrosion Gun Storage Bags
Good luck in the Air Force and enjoy boot camp.
