The intricate world of military law, particularly within the high-stakes environment of the U.S. Marine Corps, demands a unique blend of legal acumen, strategic foresight, and unwavering ethical judgment. Lieutenant Colonel Susan Upward, a Judge Advocate General (JAG) with the Marine Corps, recently offered a rare glimpse into this complex domain during an interview on the podcast "What It’s Like to Be…" hosted by bestselling author Dan Heath. Her insights shed light on the critical role JAG officers play in advising commanders on the permissibility of real-time battle decisions, navigating the complexities of soldier misconduct, and discerning the nuanced distinctions between "hostile acts" and "hostile intent" in the fog of war. The discussion also touched upon the delicate art of delivering unwelcome advice to superiors and the often-misunderstood concept of "dispo" within the military justice system.
The Dual Mandate: Legal Advisor and Commander’s Counsel
Lieutenant Colonel Upward’s role as a Marine Corps JAG is far from the courtroom dramas often depicted in popular culture. Instead, it involves a continuous, proactive engagement with operational planning and execution. Her responsibilities encompass providing legal counsel on a broad spectrum of issues, from the interpretation of international humanitarian law in active combat zones to the internal disciplinary processes governing service members.
One of the most profound challenges she described is advising commanders on the legality of actions taken in the heat of battle. In modern warfare, where technology allows for near-instantaneous decision-making and the lines between combatants and non-combatants can blur, the legal framework must be applied with extreme precision. Lieutenant Colonel Upward highlighted the necessity of understanding the nuances of the laws of armed conflict, which govern the conduct of hostilities. This includes assessing whether an action constitutes a legitimate military objective, whether the expected civilian harm is excessive in relation to the anticipated military advantage (the principle of proportionality), and whether all feasible precautions have been taken to minimize civilian casualties.
"The battlefield is not a static environment," Lieutenant Colonel Upward explained, as quoted in the podcast’s transcript. "Decisions have to be made in seconds, and those decisions have profound legal and ethical implications. Our job is to ensure that commanders have the best possible legal understanding to make those decisions within the bounds of the law and our ethical obligations."

Addressing Soldier Misconduct: Upholding Discipline and Justice
Beyond the battlefield, Lieutenant Colonel Upward’s expertise extends to the internal workings of military justice, particularly in addressing soldier misconduct. This can range from minor infractions to serious criminal offenses, each requiring a thorough investigation, legal review, and appropriate disposition. The military justice system, governed by the Uniform Code of Military Justice (UCMJ), aims to maintain good order and discipline within the ranks while ensuring fairness and due process for service members.
"When it comes to misconduct, our goal is to ensure that justice is served, but also that the process is fair and that commanders have the tools to address issues effectively," she stated. This involves advising commanders on the various disciplinary options available, such as non-judicial punishment (Article 15), administrative actions, or, in more severe cases, court-martial proceedings. The term "dispo," a common military abbreviation, refers to the disposition of a case – essentially, the outcome or how a disciplinary matter is resolved. Understanding the legal ramifications and potential consequences of each "dispo" is crucial for commanders and JAG officers alike.
The Challenge of "Hostile Acts" vs. "Hostile Intent"
A particularly thorny area of military law involves distinguishing between "hostile acts" and "hostile intent." In international law and military doctrine, an act of hostility is a direct engagement or attack. However, "hostile intent" is more subjective and can be inferred from a pattern of behavior or circumstances that suggest a predisposition to engage in hostile acts.
Lieutenant Colonel Upward’s role often involves advising commanders on how to interpret these indicators, especially in situations where direct engagement has not yet occurred but the risk is palpable. This could involve assessing the movement of individuals or vehicles, their armament, their proximity to friendly forces, and their general demeanor. The legal basis for taking preemptive action often hinges on the commander’s reasonable belief that hostile intent exists, supported by credible evidence.
"This is where judgment and experience become paramount," she noted. "You’re looking at a complex web of factors, and you have to be able to articulate why you believe a particular situation presents a clear and present danger, justifying a specific response under the rules of engagement." The potential for misinterpretation can have severe consequences, leading to unintended escalation or, conversely, a failure to adequately protect one’s forces.

The Delicate Art of Advising Superiors
A recurring theme in discussions about leadership and advisory roles is the challenge of communicating potentially unwelcome truths to those in command. Lieutenant Colonel Upward acknowledged the inherent difficulty of advising a commander whose ideas might be legally unsound or strategically flawed. The ability to do so effectively, without undermining authority or jeopardizing one’s career, is a critical skill for any JAG officer.
"You have to be confident in your legal analysis and your understanding of the operational context," she explained. "You present the facts, you lay out the legal framework, and you explain the potential consequences of a particular course of action. It’s about offering informed counsel, not dictating terms. Ultimately, the commander makes the decision, but they need to make it with full awareness of the legal risks." This often requires a diplomatic approach, framing advice in terms of mission success and risk mitigation, rather than simply stating that an idea is "colossally stupid."
Background and Context: The Evolving Landscape of Warfare
The insights provided by Lieutenant Colonel Upward are particularly relevant given the evolving nature of modern warfare. The rise of asymmetric threats, the proliferation of advanced weaponry, and the increasing role of non-state actors have created a more fluid and unpredictable operational environment. This necessitates a constant re-evaluation and application of established legal principles.
For instance, the legal framework governing the use of force against individuals who do not wear uniforms or operate from civilian areas is a subject of ongoing debate and legal interpretation. The principles of distinction and proportionality, cornerstone tenets of the laws of armed conflict, are constantly tested in these scenarios. Furthermore, the increasing reliance on technology, such as drones and cyber warfare, introduces new legal complexities that JAG officers must grapple with.
The U.S. military, including the Marine Corps, has invested significantly in legal training and resources to ensure its personnel are equipped to navigate these challenges. JAG officers are not only trained in traditional legal disciplines but also in operational planning, international law, and the specific rules of engagement applicable to various theaters of operation.

Data and Analysis: The Impact of Legal Counsel
While specific data on the direct impact of Lieutenant Colonel Upward’s advice is not publicly available, the broader implications of effective legal counsel in military operations are well-documented. Studies on military decision-making often highlight the importance of robust legal review in preventing strategic missteps and minimizing legal liabilities.
For example, historical analyses of military engagements have often pointed to instances where inadequate legal planning or disregard for the laws of armed conflict has led to significant political fallout, international condemnation, and prolonged conflict. Conversely, units with strong legal support have been shown to operate with greater clarity, reduced risk of unintended consequences, and enhanced legitimacy on the global stage.
The role of JAGs in shaping rules of engagement (ROE) is also critical. ROE are the specific directives that commanders issue to their forces to guide the application of the laws of armed conflict and to govern their actions in specific circumstances. Well-crafted ROE, informed by legal expertise, can significantly reduce civilian casualties and prevent fratricide.
Official Responses and Broader Implications
The U.S. Department of Defense places a high priority on legal compliance and adherence to international law. The Judge Advocate General’s Corps in each branch of the military serves as a critical component of this commitment. While specific reactions to Lieutenant Colonel Upward’s interview are not recorded, the principles she discussed are fundamental to the operational readiness and ethical conduct of the Marine Corps.
The implications of her insights extend beyond the immediate operational context. They underscore the vital importance of legal expertise in any organization facing complex decision-making under pressure. The ability to balance competing interests, interpret intricate regulations, and deliver candid advice are skills that resonate across various professional fields.

Moreover, the podcast episode contributes to a broader public understanding of the challenges faced by those in professions that require navigating ethical gray areas.
