Excellent resource!

As a manpower officer in the reserves, I find this extremely helpful. Not only does it list all the various codes, but the developers are very responsive to requests for updates when codes change. For example, when TNPQ changed to MS3. They updated that within several days of becoming aware of it.

Awesome app

You need this app if you do anything to do with admin! Real time saver.


Helpful, now an old friend!

The decoder app has become like an old friend with a never-ending supply of “phone-a-friend cards”!
It is my go-to in so many meetings when questions arise and people are in awe of the depth of RUAD and manning code knowledge it contains.
