What is the purpose of a fragmentary order (FRAGORD)?

• A. To publish weather updates only.
• B. To implement changes to an existing OPORD without rewriting the whole order.
• C. To draft a completely new operation plan from scratch.
• D. To assess risks after mission completion.

Answer: (B)

A FRAGORD exists to implement changes to an existing OPORD without rewriting the whole order. In fast-changing situations, commanders use fragmentary orders to update execution details—like tasking, timing, locations, or coordinating instructions—while leaving the rest of the original plan in place. This lets units adapt quickly, reduces confusion, and keeps the overall operation coherent by referencing the affected sections and indicating the effective time of the changes. The other options don’t fit because FRAGORDs are not limited to weather updates, not meant to draft a brand-new operation plan from scratch, and not used for post-mission risk assessment.
