A year does sound about right. We are currently telling applicants anything from 6-18 months. He might get lucky and get in sooner or it could take a bit longer. It all depends upon his ASVAB, physical and then the other applicants in the office. It does seem like an incredibly long wait but the numbers the CG can recruit are less and less each year. This year is no exception to that. Thank your husband for his service... and yours too! I hope all goes well.
I know you are well versed in military already being an Army wife but if you have any Coastie questions, please let us know. We'll be happy to tell you all about CG life if you ask.
