Israel’s defence minister Israel Katz declared a nationwide emergency, while the Israel Defense Forces warned of possible retaliatory missile or drone attacks and urged civilians to stay near shelters. Civilian flights were halted as Israel closed its airspace.Also Read: Israel attacks Iran with US’ help amid nuclear talks; Tehran hits back with missiles
Troop strength: Scale vs mobilisation
Iran fields one of the region’s largest military forces, with about 610,000 active personnel backed by hundreds of thousands of reservists and paramilitary members, giving it a clear numerical edge.
Its active personnel are supported not only by reservists but also by large paramilitary formations that can be mobilised for internal security, border defence and asymmetric warfare. This depth allows Tehran to sustain prolonged conflicts and operate across multiple fronts simultaneously.Also Read: Israel’s strike raises the real question: How near is Iran to nuclear weapons?
Israel’s model prioritises speed rather than size. Its standing force is far smaller, at roughly 170,000 troops, but it relies on rapid mobilisation of about 465,000 reservists, a structure designed for quick wartime expansion.
Air power: Technology against volume
Israel maintains a fleet of more than 600 aircraft, including hundreds of fighters, attack helicopters and specialised surveillance planes that enhance precision targeting and intelligence gathering. Its air arm is structured around technological superiority, precision strike capability and networked warfare. Its fleet includes advanced fighters, electronic warfare aircraft, airborne early-warning systems and intelligence platforms that provide real-time battlefield awareness.
This integrated approach allows it to conduct long-range missions and hit multiple targets with accuracy.Iran operates slightly fewer aircraft overall and fewer specialised platforms. Much of its fleet consists of older models, though Tehran offsets this through missile and drone programmes. To offset this, Iran has invested heavily in drones, cruise missiles and layered air-defence systems, creating a strategy that blends conventional aviation with stand-off strike capability.
Ground forces: Heavy numbers vs precision warfare
Iran possesses between 1,700 and 2,000 tanks, tens of thousands of armoured vehicles and more than 1,500 mobile rocket launchers, giving it strong conventional firepower. Its land forces reflect a doctrine built around mass and saturation.
Large tank inventories, extensive armoured transport fleets and rocket artillery units enable it to deploy dense firepower across wide areas. Such capabilities are suited for territorial defence and attrition-based combat scenarios.
Israel deploys fewer tanks and armoured vehicles but emphasises mobility, advanced targeting systems and self-propelled artillery suited for fast-moving operations. It, in contrast, centres on manoeuvre warfare. Its armoured units are supported by advanced sensors, targeting software and precision munitions that allow smaller formations to strike effectively.
Naval balance: Regional reach vs strategic detterence
Iran’s navy focuses on controlling nearby waters and leveraging geography. Its mix of submarines, fast attack craft and missile-armed patrol vessels is tailored for operations in narrow sea lanes, where swarming tactics and coastal missile systems could challenge larger adversaries.
Israel’s maritime strategy is narrower but highly specialised. Its submarine fleet is widely regarded as a key component of strategic deterrence, while missile-equipped surface ships provide coastal protection and rapid strike options. Rather than projecting power globally, its naval posture is geared toward safeguarding national waters and deterring escalation.
Defence spending gap
Financial resources sharply diverge. Israel spends about $30.5 billion annually on defence—roughly double Iran’s estimated $15.45 billion—allowing for advanced procurement and research. The country’s significantly larger defence budget supports continuous upgrades, research programmes and acquisition of cutting-edge systems, helping it maintain a technological edge across domains such as cyber warfare, missile defence and surveillance.
Iran, facing sanctions, has prioritised domestic weapons production and missile development to compensate for tighter budgets.
Global standing
In the 2026 ranking by Global Firepower, Israel placed 15th worldwide while Iran ranked 16th, reflecting broadly comparable conventional strength across dozens of indicators.
A key wildcard is Israel’s close ties with the United States. U.S. President Donald Trump has reportedly ordered additional forces, including a second aircraft carrier, toward the region, signalling rising concern that the confrontation could widen.
Escalation risks rise
The latest strikes, emergency alerts and force deployments on both sides point to a rapidly intensifying standoff. Analysts warn that with both militaries possessing significant offensive and defensive capabilities, even limited retaliation could trigger a cycle of escalation that draws in regional actors and disrupts energy routes, trade flows and air travel across the wider Middle East.
