I can help. If you're Christian, you will be treated like s--t at Navy OCS. If you are NOT Christian, you will be treated like s--t at Navy OCS.
I realize that this doesn't answer the question. I am a Christian, and I went through Navy OCS. All I can say is, it's tough. My Bible (the only non-OCS and non-contraband reading there) was a big help. It was the only way I could get away from the OCS environment until we were able to take liberty. A great help, but by no means necessary.
If your question goes deeper, as Michael alluded to, then you'llnot find the answer at OCS; and perhaps you should find it elsewhere before agreeing to go...
