I'm considering enlisting as an OS in part to obtain the $30k bonus. My recruiter told me I can get BAH of $1,600 and more as a single man. I understand there's a possibility of being denied BAH as an OS due to being stationed on a cutter. I imagine that same possibility exists for practically every rate, right? If not, which rates are those? If it does then which rates have the greatest chance of being given BAH?

BAH amounts are different for every zip code, google BAH calculator to check specific zip codes BAH rates. The job you choose in the coast guard has no bearing on whether you get BAH or what amount you get You get BAH if you live on economy, plain and simple. As a single member there is a higher probability that you will live in a barracks or on a cutter and will not receive BAH.

Thank you jdhusker! As far as I understood my recruiter my dad and I were told that the CG doesn't have barracks so BAH is likely to be given as a result. I guess my dad and I greatly misunderstood him, yeah?

The bigger units and bases usually have a barracks and single members E4 and below are generally required to live in the barracks if it's available. But you are partially correct, many units do not have a barracks. I am not familiar enough with the OS rating to know how likely it is that you would go to a unit with a barracks.

Helpful information jdhusker! Thank you!
