an OPORD may be forthcoming. Time and circumstances permitting, a WARNORD is issued to subordinate leaders immediately after receipt of the unit's mission from higher. This is intended to provide subordinates time to develop their own warning and operations orders based on information contained within the WARNORD. A fragmentary order (FRAGORD ) informs units that one or more elements of the base order have changed. Once an OPORD is given, the situation may change before the mission begins, or, during the operation the situation may change so that the base order must be modified. In these cases the commander will issue a FRAGORD. The FRAGORD follows the same format as the base order but only states the changes that must be made.
