Despite rhetoric of mass mobilization, defense budget constraints and modern warfare costs make maintaining a million-strong force beyond Tehran’s financial and logistical capacity
Iran does not have the resources to sustain a force of one million troops in preparation for a potential U.S. amphibious landing, despite rhetoric suggesting large-scale mobilization.
While such statements may sound like a call to arms, the reality of Iran’s financial and military capacity tells a different story.
Iran’s defense budget stood at approximately $7.9 billion in 2024, according to SIPRI. Even under more generous estimates, total military spending reaches just over $20 billion annually. This translates to roughly $1–2 billion per month to fund the entire military, covering salaries, logistics, weapons systems, missiles, and air defense.
By contrast, maintaining a one-million-strong force under modern warfare standards would require at least several billion dollars per month. Basic costs such as food, salaries, and operations alone would amount to hundreds of millions of dollars, excluding expenses for training, equipment, and maintenance. Total annual costs could rise to between $30 billion and $50 billion.
Currently, Iran spends an estimated $10–20 billion annually to sustain a force of around 600,000 personnel. Expanding to one million troops would require approximately $40 billion per year—two to four times its existing defense budget.
Moreover, modern warfare is no longer determined by sheer troop numbers. In recent conflicts, the United States has demonstrated the ability to spend more than $11 billion within just a few days to dismantle an adversary’s air force, air defense systems, and naval capabilities—levels of expenditure Iran cannot match, even in the short term.
While Iran may be able to mobilize large numbers of personnel when necessary, it lacks the financial and logistical capacity to sustain a one-million-strong military force for a conflict against the United States. Oil revenues remain constrained, and external pressures continue to limit its economic flexibility.
