I am going to Navy OIS and have heard a lot of talk about how Navy OIS has gotten much harder than it was 3 or 4 years ago. From what they are saying it is on par with OCS. I understand that they did away with a lot of the weekend leave. However, OIS has been cut from 6 weeks to 4 weeks so I undertsand the need to get rid of leave. Can anyone that has been to OIS last year or the year before let me know how OIS is now. Any advise from those who have gone would be helpful too.
