The Marine Corps is releasing a new digital application that all units must use to meet requirements for operational Situation Reports, or SITREPs, the service announced.

The app, called the Operational Data Integration Nexus (ODIN), will be housed in the Defense Department’s Maven Smart System. The MSS platform, powered by AI, was built by Palantir and has been widely adopted across the military, including by combatant commands.

ODIN is slated for release July 7 and will serve as the “official reporting tool for Marine Corps Operational SITREPs, operations, activities, and investments, and custom report generation,” according to a MARADMIN message posted Monday.

A Marine Corps press release issued Tuesday described ODIN as a “next-generation, data-centric decision support tool.”

“Historically, Marine Corps operational reporting has relied on a document-centric process where units at each echelon manually create and consolidate narrative Situation Reports (SITREPs). This method consumed valuable operational time, created information silos, and hindered operational tempo,” officials wrote in the release.

“ODIN dramatically reduces administrative workloads by automating data entry through integration with authoritative databases, allowing leaders to focus entirely on warfighting and operational intent. The system contextualizes disparate data into actionable insights, enabling commanders to manage risk dynamically and operate inside the adversary’s decision cycle,” the release added, noting that the technology will also allow for data sharing between units.

Ahead of the app’s release, the deputy commandant for plans, policies, and operations is expected to issue a task order providing instructions and the access link for the ODIN capability in the Maven Smart System. The Marine Corps acquired an enterprise license for MSS last year.

“Commanders must activate their MSS licenses and designate key personnel to do the same to ensure compliance with the task order for SITREP reporting via the ODIN,” per the MARADMIN message.

Lt. Gen. Jay Bargeron, deputy commandant for plans, policies, and operations, touted the new technology in Tuesday’s press release.

“ODIN is more than a reporting tool; it is a strategic asset that returns valuable time to our commanders,” he stated. “By automating the flow of data from the tactical edge to strategic decision makers, we are equipping our Marines with the near real-time information required to outpace our adversaries and fight effectively in a distributed environment.”
