  1. I’d like to see more of government manuals covering the concept of how to reduce cost such as that in Army regulation for writing correspondence. Private industry does this all the time. It is commonplace.

  2. Neil O'Donnell

    Proper formatting of correspondence and reports is essential to making sure orders and requests are conveyed accurately and in a timely manner. Failure to comply with established formats could lead to a loss of critical data, which in turn could leave the success of a mission in doubt. Consequently, it sounds like the AR 25-50 should definitely be a book that commanders study and pay heed to.

    1. AR 25-50 is an important regulation for everyone serving in the Army. Everyone should know how to draft correspondence so it is accurate and formatted properly. This gives you extra credibility.
