Decoder for US Navy vs Naval Library & Modern Warship

This application is not officially endorsed or sponsored by the US Navy. This app is a quick reference guide to many US Navy personnel and other codes. Instead of spending the time to find the correct reference and look up the information, this app will allow one to quickly get to the answer. The main focus currently is on personnel related codes that will be found in manning documents such as RUADs and AMDs. Current items decoded: - Additional Qualification Designations - Enlisted Rating Codes - IMS Codes - MAS Codes - Officer Billet Codes - Officer Designators - Officer Paygrade Codes - Navy Reserve Activity Codes - NOBC Codes - RBSC Billet Codes - Reserve Program Codes - Reserve Unit Identification Codes - RFAS Codes - Subspecialty Codes - NECs See how you can support this open source project: https://github.com/ctd-mh3/NavyDecoder-OpenSource-iOS
