  Brief and order types are distinguished by--
  • Time--When the order or brief occurs.
  • Contents--What the order or brief includes.

  Section I. ORDERS
  This section discusses the three types of orders (FM 1-02). A WARNO is a preliminary notice of an order or
  action that is to follow. A OPORD is a directive issued by a commander to subordinate commanders for the
  purpose of effecting the coordinated execution of an operation. A FRAGO is issued after an OPORD to change,
  modify, or execute a branch or sequel to that order. WARNOs follow the five-paragraph OPORD format.
  FRAGOs also follow the OPORD format, but seldom include all five paragraphs. For extensive changes, the
  leader normally issues a new OPORD.
  WARNING ORDER
  B-1. Leaders issue WARNOs as soon as they complete their initial assessment of the situation and
  available time. Leaders do not wait for more information. They issue the best WARNO possible with the
  information at hand and update it as needed with additional WARNOs. The WARNO follows the
  five-paragraph OPORD format (Figure B-1 (page B-3) shows an example WARNO). The WARNO
  contains as much information as possible. Normally an initial WARNO includes--
  • Mission or nature of the operation.
  • Time and place for issuing the OPORD.
  • Units or elements participating in the operation.
  • Specific tasks not addressed by unit SOP.
  • Time line for the operation.
  B-2. The WARNO may also include--
  • The higher unit's mission statement.
  • Commander's intent.
  • Commander's WARNO.
  • Commander's operations brief or order.
  • Task organization changes.
  • Attachments/detachments.
  • The unit AO.
  • Initial intelligence requirements or CCIR.
