Abstract

This paper examines the divergent models of military organisation and combat motivation in the contemporary world, focusing on the contrast between the professional, “extractive” model exemplified by the United States and the “sons of the soil” model exemplified by Iran. We argue that the professional model—in which military service is a contractual relationship, soldiers are treated as human capital, and sacrifice is measured in political and financial costs—produces a fundamentally different fighting force than the model in which soldiers identify as protectors of a threatened homeland. Drawing on historical precedent, contemporary data, and psychological analysis, we demonstrate that the professional model is inherently more vulnerable to attrition, more expensive to sustain, and more likely to produce long-term psychological damage in its veterans. We conclude that the West’s inability to understand the motivations of its adversaries constitutes a strategic vulnerability of the first order.

1. Introduction: The Question That Defines the Battlefield

“For whom would you die?”

This question, posed by Andrew Klein, is not rhetorical. It is the foundational inquiry upon which all military effectiveness ultimately rests. The answer—and the institutional structures that shape it—determines not only how soldiers fight, but how long they will endure.

In 2026, the United States Navy faces an unprecedented crisis. Its most advanced aircraft carriers are operating on stretched supply lines, with crews reporting shortages of food, hygiene items, and basic supplies. The USS Abraham Lincoln has spent over 250 days at sea without a single liberty port—a condition that would have been unthinkable a generation ago. Meanwhile, the Iranian Revolutionary Guard Corps, under sustained military pressure and severe economic sanctions, continues to maintain operational effectiveness.

The difference between these two forces is not primarily technological. Both possess advanced weapons systems. Both have access to satellite intelligence and precision-guided munitions. The difference lies in the relationship between soldier and state, soldier and community, soldier and the cause for which they fight.

2. The Professional Model: The Soldier as Human Capital

2.1 The Origins of the Professional Army

The modern professional army emerged in Europe in the 17th and 18th centuries, as states replaced feudal levies with standing, paid forces. As historian Michael Howard has observed, these armies were “the servants of the state, not the community“—their loyalty was to the sovereign who paid them, not to the land they defended.

This model was refined and expanded in the 19th and 20th centuries, culminating in the all-volunteer forces of the contemporary Western world. Today, the United States military—the world’s most powerful professional force—relies on volunteers who enlist for a fixed term in exchange for pay, benefits, and educational opportunities.

2.2 The Extractive Logic of the Professional Model

As Andrew Klein has argued, the professional military operates according to the logic of the extraction economy:

· Soldiers are human capital. Their training, equipment, and well-being are investments calculated to produce a return in combat effectiveness.

· Risk is outsourced. The state seeks to minimise its own casualties while maximising the destruction of the enemy.

· Sacrifice is quantified. Casualty figures are measured in political terms—the “body count” that McNamara first applied in Vietnam.

This model requires significant financial investment. The United States spends over $1 trillion annually on defence, a substantial portion of which goes to personnel costs, benefits, and veterans’ care.

2.3 The Treatment of Veterans: Disposable Assets

Perhaps the most revealing aspect of the professional model is its treatment of veterans once their service is complete. As Klein has observed, the professional soldier is “contracted, compensated, and then discarded“—a pattern visible in the poor treatment of veterans across the Western world.

In Australia, the Royal Commission into Defence and Veteran Suicide, which reported in July 2024, found that current and former ADF members are 2.5 times more likely to die by suicide than the general population. Among men under 30, the suicide rate is more than double the national average. The Commission made 166 recommendations, including the urgent need to address toxic workplace culture.

The United States faces a similar crisis. Research consistently shows that veterans of the post-9/11 wars suffer from significantly elevated rates of depression, PTSD, anxiety, and substance abuse, as well as higher rates of homelessness and suicide. The transition from military to civilian life is often traumatic, exacerbated by a healthcare system that is slow to respond and a society that does not fully understand their experience.

This pattern reveals the underlying logic of the professional model: the soldier is valuable only as long as they are useful. Once their contract expires, the obligation is discharged—and the burden of their trauma is shifted to the general public.

3. The Sons of the Soil Model: The Soldier as Protector

3.1 The Historical Precedent: The Citizen-Soldier

The “sons of the soil” model represents an alternative tradition, one in which military service is not a contract but a sacred obligation. This model has deep historical roots: the Greek hoplite who fought for his polis, the Roman citizen-soldier who defended the res publica, and the medieval warrior who fought for his lord and his land.

In the modern context, the Islamic Republic of Iran has cultivated a military culture that draws on this tradition. The Iranian Revolutionary Guard Corps (IRGC) was established in 1979 to protect the revolution and its ideological foundations. Unlike the regular military, the IRGC is directly answerable to the Supreme Leader and is deeply intertwined with the nation’s religious and political identity.

3.2 The Logic of the Sons of the Soil

The sons of the soil model operates according to a different logic:

· The soldier is a guardian. Their role is to protect their family, their community, and their faith.

· The threat is existential. Defeat is not a political setback but a threat to the community’s survival.

· Sacrifice is honoured. Martyrdom is not a tragedy but a fulfilment of purpose.

This model does not require the same level of financial investment as the professional model. Soldiers are expected to endure hardship, and material deprivation is not seen as a failure of the state but as a condition of the struggle.

3.3 The Role of Martyrdom in Iranian Military Culture

The concept of shahadat (martyrdom) is central to Iranian military culture. The memory of the Iran-Iraq War (1980-1988), in which an estimated 200,000-500,000 Iranians died, is still alive in the national consciousness. Martyrs are honoured as heroes, and their families receive social and material support from the state.

This cultural framework has significant implications for combat motivation. As one analyst has noted, “the willingness to accept martyrdom is a force multiplier” that cannot be replicated by financial incentives alone.

4. Comparative Analysis: Fighting Spirit and Combat Motivation

4.1 The Psychology of Sacrifice

The question “For whom would you die?” reveals a fundamental difference between the two models:

· In the professional model, the soldier fights for their comrades, their country, and their own survival. The bond with the state is contractual and conditional.

· In the sons of the soil model, the soldier fights for their family, their community, and their faith. The bond is existential and unconditional.

Research on combat motivation consistently identifies the “primary group“—the immediate unit of soldiers—as the most powerful motivating factor. As S.L.A. Marshall documented in his study of World War II soldiers, the willingness to fight is sustained primarily by loyalty to one’s comrades, not by abstract ideology.

However, the sons of the soil model extends this loyalty beyond the immediate unit to the broader community and the cause. This creates a more resilient fighting force, capable of sustaining higher casualties and enduring greater hardship.

4.2 The Material Factor

The professional model requires a significant material base: high salaries, quality equipment, regular rotations, and a robust logistics network. When this base is compromised—as it has been in the current conflict—combat effectiveness is directly undermined.

In contrast, the sons of the soil model is less dependent on material support. Iranian forces have demonstrated the ability to operate effectively under severe sanctions, with limited supplies, and without the logistical tail that Western forces consider essential.

4.3 Mental Health Outcomes

The comparison between Western and Iranian veterans is instructive. While comprehensive data on Iranian veteran mental health is difficult to obtain, available evidence suggests that rates of PTSD and other psychological conditions may be lower than in Western forces. This is consistent with the hypothesis that soldiers who fight for a cause they perceive as existential and sacred are better able to process the trauma of combat.

The Royal Commission into Defence and Veteran Suicide found that Australian veterans experience significantly higher rates of suicide and mental illness than the general population. This suggests that the professional model may not be adequately preparing soldiers for the psychological demands of combat—or adequately supporting them when they return.

5. The Strategic Implications: What the West Does Not Understand

5.1 The Asymmetry of Will

The West’s reliance on the professional model creates a fundamental asymmetry in conflicts with adversaries who embrace the sons of the soil model. Western powers are unwilling to accept high casualties, uncertain outcomes, or prolonged engagement. Their adversaries, by contrast, are prepared to endure all three.

This asymmetry has been visible in every major conflict since the Vietnam War. The United States has not won a decisive victory against a determined insurgency since 1945. Its military superiority has not translated into political success.

5.2 The Extraction Model and Its Limits

As Andrew Klein has argued, the professional military model is a component of the broader extraction economy. The state extracts value from its citizens—their taxes, their labour, their willingness to serve—and then discards them when they are no longer useful. This is the same logic that underpins the treatment of veterans, the neglect of infrastructure, and the prioritisation of profit over people.

The limits of this model are becoming increasingly visible. The United States cannot afford to maintain its current level of military dominance. Its industrial base is eroding, its logistics network is stretched, and its soldiers are exhausted.

5.3 The Failure to Understand the Enemy

The West’s inability to understand the motivations of its adversaries is a strategic vulnerability of the first order. Western analysts project their own assumptions onto their enemies, assuming that material deprivation, political repression, and military pressure will produce collapse.

But as Iran has demonstrated, these assumptions are not always correct. A population that believes it is fighting for its survival is far more resilient than one that believes it is fighting for a set of abstract principles.

6. Conclusion: The Soldier and the State

The question “For whom would you die?” is not merely philosophical. It is the central strategic question of our time.

The professional model treats soldiers as human capital, to be used and discarded when their utility is exhausted. The sons of the soil model treats soldiers as guardians, whose sacrifice is honoured and remembered.

These two models produce fundamentally different fighting forces. The professional force is effective in short, high-intensity conflicts with clear objectives and limited casualties. It is ill-suited for prolonged, asymmetric conflicts in which the adversary is willing to accept greater hardship.

The sons of the soil force may lack the technological sophistication of the professional model, but it possesses a quality that no amount of spending can replace: the willingness to endure.

As we have seen in the Iran-US conflict, this quality matters. The U.S. Navy’s logistical crisis is not merely a technical failure. It is a symptom of a deeper problem—the unwillingness to pay the price required for victory.
