Chief Warrant Officer 5 (CWO5) Stephen LaRose, a highly decorated Marine gunner known for his transformative contributions to military doctrine and lethality, is currently facing a court-martial at Marine Corps Base Quantico, Virginia. The trial, which began on December 17, 2024, involves serious charges, including unauthorized absence (UA), dereliction of duty, false official statements, and conduct unbecoming an officer.

A Storied Career

According to Military Times, Chief Warrant Officer 5 (CWO5) Stephen LaRose has had an illustrious career in the United States Marine Corps, serving in several high-profile roles that highlight his expertise and dedication. As a Marine gunner (officially known as infantry weapons officers), he was recognized as one of the Corps’ leading weapons specialists. From 2020 to 2022, he served as an advisor on the Defense Department’s Close Combat Lethality Task Force (CCLTF), where he worked to enhance the effectiveness of close-combat units. LaRose also provided unofficial guidance to the Marine Corps Warfighting Lab, further cementing his reputation as a key figure in military modernization.

LaRose’s contributions have earned him numerous accolades, including two Bronze Stars, the Defense Superior Service Medal, and the National Infantry Association’s St. Maurice award. He is well-known for his published insights on military doctrine and lethality, particularly his vocal support for the Marine Corps’ Force Design 2030 strategy, which he has discussed in various publications. Over his career, LaRose worked closely with high-ranking officials, including former Marine Corps Commandant Gen. David Berger, and his unique role as a Marine gunner allowed him to operate with greater autonomy, often bridging different levels of command.

As a veteran of the wars in Iraq and Afghanistan, LaRose sustained injuries during his deployments, which influenced his later assignments. His career transitioned toward civilian life in 2022-2023, during which he accepted a position with the defense contractor ManTech.

However, this transition period has led to the current court-martial proceedings, with charges of unauthorized absence, dereliction of duty, and conduct unbecoming a Marine officer, casting uncertainty over the legacy of an otherwise distinguished career.

The Charges: Context and Controversy

The allegations against LaRose center on his service from 2022 to 2023, a transitional period during which he moved from active duty to civilian life. During this time, LaRose served as an advisor to the Defense Department’s Close Combat Lethality Task Force (CCLTF), established in 2018 by then-Defense Secretary Jim Mattis. The task force, aimed at enhancing close-combat unit effectiveness, underwent a leadership transition in 2021, with the Army taking charge and relocating its headquarters to Fort Moore, Georgia.

This restructuring led to significant administrative changes for Marine Corps personnel like LaRose, who shifted to a “matrix support” model, providing remote assistance from the Washington, D.C., area. The resulting ambiguities in his chain of command and duties have become central to his defense.
