The Iranian army is generally estimated at around 350,000 ground troops within a total active force of about 600,000+ military personnel , plus several hundred thousand reservists and large paramilitary forces.

Quick Scoop: How Big Is the Iranian Army?

When people ask “how big is the Iranian army?” they usually mean two slightly different things:

  1. the regular ground army (Artesh), and
  2. the whole military machine including the Revolutionary Guard and paramilitaries.

1. Core Numbers (Latest Open Estimates)

  • Total active military personnel (all branches) : about 600,000–610,000.
  • Regular army (Artesh) total : about 420,000 personnel , including ground, air, navy, and air defense.
  • Ground forces of the regular army : about 350,000 soldiers , most of them conscripts.
  • Islamic Revolutionary Guard Corps (IRGC) : roughly 190,000 personnel in its own ground, naval, and aerospace branches.
  • Reserves : around 350,000 reserve and trained personnel that can be mobilized.
  • Paramilitary (Basij and others) : hundreds of thousands; estimates often put total paramilitary forces in the hundreds of thousands to close to a million potential mobilizable members, though only a fraction are fully combat ready.

Put simply:

In a major crisis, Iran could potentially mobilize around a million people or more when combining active, reserve, and paramilitary elements, though quality and readiness vary widely.

Mini Breakdown: Branch by Branch

Here’s a compact picture of the force structure as described in public sources:

  • Regular Army (Artesh)
    • Ground Forces: ~350,000 (many conscripts).
* Navy: ~18,000–18,500.

* Air Force: ~37,000–42,000.
  • IRGC (Revolutionary Guard)
    • Approx. 190,000 personnel total.
* Has its own ground forces, naval arm (focus on Persian Gulf), and aerospace force (including missiles).
  • Basij (paramilitary under IRGC)
    • Membership claimed in the millions , but only a smaller subset (hundreds of thousands) is seen as combat-capable.

These figures help explain why Iran is often ranked among the largest armed forces in the Middle East in terms of manpower.
