OPREP 1 is a series of codenamed high-magnitude incident reports/operational reports used by the UNSC Defense Force from 2553 onwards. It was the successor to the Operational Reports-Γ Reporting Structure employed during the Human-Covenant War. Intelligence attained from OPREP 1 reports is of the highest priority and is used to inform and determine the posture and alert levels of all UNSC units throughout UNSC space.

Given the severity of incidences that are reported through OPREP 1, submission of an OPREP 1 report is almost always followed by a OPORD (operational order) that organizes a UNSC military response to the reported event.

In 2560, OPREP 1 TEMPEST was declared when the ONI Radio Intelligence Program's Magnetosphere Study Group detected high-energy exchanges in the polar regions of Gliese 876 D (Bellerophon), presumably the usage of high-magnitude directed energy weapons. This was upgraded to an OPREP 1 FURY when ONI reconnaissance satellite coverage was lost over the polar regions, and it was presumed that this was due to an electronic warfare attack that was the first phase of a imminent invasion on Bellerophon itself.

As per OPREP 1 FURY, forces of the UNSC Second Fleet and several Fleet Marine Forces were immediately deployed to reinforce UNSC forces on Bellerophon and to defend against an imminent planetary invasion.

Categorization of events

 * OPREP 1 FURY: Declaration of an alpha-class event. Signifies an imminent or ongoing major attack against UNSC forces or infrastructure. Doctrinally followed by a UNSC military counterattack.
 * OPREP 1 TEMPEST: Declaration of a beta-class event. Signifies the usage of high-energy weapons of mass destruction (thermonuclear, electromagnetic, or plasma).
 * OPREP 1 STORM: Declaration of a beta-class event. Signifies the usage of chemical or biological weapons of mass destruction.
