Preparing and Managing Correspondence

AR 25-50 is the standard for Army correspondence: memorandums, letters, and the rules for signature blocks, distribution, and endorsements. It is the reference that decides arguments about formatting in an S1 shop. The 10 October 2020 edition is still the current one.

What to take from it

  • Authorizes three forms of correspondence: the letter, the memorandum, and the message.
  • The memorandum is the standard internal Army correspondence format.
  • Prescribes the rules for signature blocks, suspense dates, endorsements, and enclosures.
  • Applies Army-wide, including the Army National Guard and the Army Reserve.
