Gaza War · 2023 – Present
The Gaza War that began on October 7, 2023 is a conflict of profound asymmetry in military hardware but striking parity in strategic determination. Israel possesses one of the world's most sophisticated military establishments — Merkava tanks, F-35 stealth fighters, Iron Dome missile defense, precision guided munitions, and cutting-edge intelligence systems. Hamas possesses Qassam rockets built from improvised components, RPGs, small arms, and an underground tunnel network 500+ kilometers long that functions as a force multiplier, logistics system, and protection that negates much of Israel's air power advantage. The war has tested the limits of conventional military superiority against an entrenched urban insurgency — a challenge no military has yet solved.
Iron Dome is Israel's short-range missile defense system, designed specifically to intercept and destroy short-range rockets fired from Gaza and Lebanon. Each battery uses radar to detect incoming projectiles, calculates impact trajectory, and fires Tamir interceptor missiles only at rockets threatening populated areas — leaving those headed for open fields to land harmlessly. Iron Dome has achieved approximately 90% interception rates against the thousands of Hamas rockets fired since October 7, 2023. Without it, the scale of Israeli civilian casualties would have transformed the conflict's political dynamics fundamentally.
Significance
Iron Dome represents the most successful missile defense system in combat history. Its existence enables a strategic paradox: it protects Israeli civilians from Hamas rockets well enough to reduce the pressure for ground military operations, while Hamas's ability to fire rockets despite Iron Dome — even at 10% penetration — maintains psychological pressure on Israeli society. The system costs roughly $50,000 per Tamir interceptor, fired against Qassam rockets that cost $800. Sustaining this exchange rate at scale is an economic challenge that ultimately reflects favorably on the defender.
The Merkava Mk IV is Israel's most advanced tank, uniquely designed with the engine in the front to provide additional crew protection — a design philosophy born from the Yom Kippur War's tank losses. It is equipped with the Trophy active protection system (APS), which detects and intercepts incoming RPG rockets and anti-tank missiles before they strike the tank. In Gaza, Trophy-equipped Merkavas have intercepted hundreds of anti-tank rockets fired from ambush in urban terrain. The tank's rear loading ramp allows it to carry infantry or evacuate casualties — a capability critical in urban fighting where tanks and infantry must operate together.
Significance
The Merkava IV in Gaza demonstrated that active protection systems have matured to the point of operational viability — a development as significant for armor as guided missiles were in 1973. But the tank's strengths were also its limitations: effective in force protection and close infantry support, it struggled against the tunnel system beneath Gaza's buildings, where Hamas fighters could emerge behind armor, attack the vulnerable rear, and disappear underground before responding forces arrived.
Israel's F-35I 'Adir' is a domestically modified version of the Lockheed Martin F-35A, with Israeli avionics, electronic warfare systems, and weapons. It is the most advanced operational combat aircraft in the Middle East. In Gaza, the F-35's stealth and precision strike capabilities — 900 kg JDAM-ER bombs guided to within meters of their targets — have allowed Israel to strike Hamas infrastructure in dense urban areas. The aircraft's synthetic aperture radar, electronic warfare suite, and sensor fusion allow it to identify targets at night, in bad weather, and through urban clutter. Against Hamas targets that do not include air defense, the F-35's stealth is irrelevant; its sensor suite and precision strike capability are decisive.
Significance
The F-35 in Gaza represents the apex of precision strike capability against an enemy that has deliberately co-located military infrastructure with civilian population. The aircraft can reliably deliver a bomb to within meters of a specified target — but the military-civilian proximity in Gaza means that precision does not eliminate civilian casualties; it reduces them while the overall volume of strikes determines the ultimate toll. The F-35's capabilities test the limits of proportionality doctrine: precise enough to be unquestionably accurate, yet operating in a target environment where accuracy and proportionality are different questions.
The Caterpillar D9R, heavily armored by Israel and operated by IDF Combat Engineering Corps, has been one of the most decisive weapons systems in the Gaza ground campaign. Armored against small arms and RPG fire with add-on steel plates and IDF-developed crew protection kits, the D9R leads IDF infantry advances through booby-trapped streets, demolishes buildings used as fighting positions, and opens breaches through building walls to allow infantry movement without using exposed streets. It also excavates and destroys tunnel shafts located during clearing operations. In a conflict defined by urban density and underground warfare, the armored bulldozer has proven as decisive as any combat vehicle.
Significance
The D9R's prominence in Gaza has sparked intense international controversy — Human Rights Watch and Amnesty International have documented cases where D9Rs demolished homes with civilians still inside, or were used in large-scale demolitions of civilian infrastructure. Israel argues these demolitions are militarily necessary to remove cover for Hamas fighters and destroy tunnel infrastructure. The debate over bulldozer use has become a microcosm of the broader international law debate over proportionality and military necessity in urban warfare.
Hamas's locally manufactured rockets range from the basic Qassam (range 10–17 km, accuracy near zero) to the longer-range M-75 and J-80 rockets reaching Tel Aviv and Haifa. Built from steel pipes using sugar and potassium nitrate propellant, Qassams cost approximately $800 each. More capable variants — the M-75, reaching ~75 km — are based on Iranian designs and had to be smuggled in components or manufactured locally. Since October 7, Hamas and Islamic Jihad have fired over 25,000 rockets at Israel, ranging from border-area harassment to deep strikes on Tel Aviv and Ben Gurion Airport.
Significance
The rocket arsenal serves simultaneously as a tactical weapon (forcing IDF to devote resources to defense) and a strategic one (maintaining psychological pressure on Israeli society). Iron Dome intercepts the vast majority, but even 5–10% penetration against 25,000 rockets means hundreds of impacts on populated areas. The economic cost of interception — $50,000 per Tamir interceptor vs. $800 per Qassam — creates an asymmetric exchange that favors the attacker financially despite the defender's military superiority.
Hamas's anti-armor arsenal includes the RPG-29 (a Soviet-era rocket-propelled grenade capable of penetrating modern tank armor with its tandem-charge warhead) and the Russian 9M133 Kornet laser-guided anti-tank missile. The Kornet, with a range of 5.5 km and a tandem HEAT warhead, was responsible for significant IDF armored vehicle casualties. Hamas's sophisticated use of these weapons — firing from tunnel ambush positions, using civilian structures for cover, and targeting the vulnerable sides and rear of armored vehicles — demonstrated a much higher level of combined-arms proficiency than previous Gaza campaigns.
Significance
Hamas's anti-armor capability forced fundamental changes in IDF urban tactics. Trophy APS on Merkava IVs intercepted hundreds of incoming RPG shots — but not every hit was intercepted, and the psychological and physical toll on IDF crews operating in ambush-heavy terrain was significant. The effectiveness of Kornet missiles against Israeli armored personnel carriers (which lack Trophy) was particularly high, contributing to some of the war's worst Israeli casualty events.
Hamas's tunnel network — which Israeli officials and media call 'the Metro' — is estimated at 500+ kilometers of tunnels beneath the Gaza Strip, with shafts beneath homes, mosques, hospitals, and schools. The network functions as a command center, weapons storage and production facility, logistics system, and protection for leadership and fighters. Tunnels are reinforced with concrete, equipped with electricity, ventilation, and communications, and run deep enough (20–40 meters) to survive most air strikes. Israeli ground operations in Gaza have been substantially shaped by the need to locate, map, and destroy tunnels — a task that requires time-consuming engineering work and exposes infantry to ambushes from underground.
Significance
The tunnel network is Hamas's strategic center of gravity and its most effective force multiplier. It negates Israeli air superiority — bombs that level above-ground structures leave tunnels intact. It enables surprise — fighters emerge from unexpected locations, strike, and disappear. It provides protection for leadership that prevents decapitation strikes. Israel's primary strategic challenge in Gaza is not defeating Hamas's soldiers but destroying infrastructure that required a decade and hundreds of millions of dollars to construct. The tunnels represent a commitment to the long war that no amount of firepower can rapidly reverse.
Israel has maintained a naval blockade of the Gaza Strip since 2007, enforced by the Israeli Navy's Sa'ar-class missile corvettes and patrol boats. The blockade restricts maritime access to Gaza's coastal waters, preventing weapons smuggling by sea. During the Gaza War, the Navy enforced a strict exclusion zone and interdicted attempted supply vessels. The Navy also conducted fire support missions against Hamas coastal infrastructure, tunnels near the beach, and shore-based rocket launch sites. In early 2024, the Navy coordinated with the US 5th Fleet to monitor potential Hezbollah or Iranian maritime threats.
Significance
The blockade has been a source of intense international legal debate — the 2010 flotilla incident, in which IDF commandos killed 10 Turkish activists on the Mavi Marmara, triggered a diplomatic crisis with Turkey. During the current war, the blockade's restriction of humanitarian aid via sea — before the US Pier project attempted temporary relief — contributed to the humanitarian crisis and international condemnation.
The IAF has employed a range of precision-guided munitions throughout the Gaza campaign, including the US-supplied JDAM-ER (Joint Direct Attack Munition Extended Range) which adds GPS guidance and wings to standard gravity bombs, giving them 70+ km standoff range, and Israel's own Spice family of autonomous bomb guidance kits — using electro-optical and GPS guidance to hit specific windows within a structure. The GBU-28 bunker-busting bomb has been used against Hamas tunnels. The GBU-39 Small Diameter Bomb, weighing only 250 lb but guided to within meters, has been used in dense urban areas to minimize blast radius.
Significance
Israel's extensive use of precision munitions was both militarily essential and insufficient to prevent mass civilian casualties. With Hamas co-locating military assets inside apartment buildings, hospitals, and refugee camps, even a precisely placed bomb that destroys a valid military target also destroys the surrounding structure. The precision debate became central to international legal proceedings: Israel argued each strike was precise; critics argued the targets were improperly chosen and civilian casualties disproportionate regardless of technical accuracy.
The Soviet-era RPG-7 remains the most common anti-armor and anti-personnel weapon in Hamas's arsenal. Cheap, rugged, and easily manufactured or sourced, it has been produced in Gaza locally and smuggled from Iran, Egypt, and elsewhere for decades. In Gaza's urban terrain, where engagement distances are measured in meters, the RPG-7's short range is not a limitation. Hamas fighters have used it against Israeli infantry, light vehicles, drones, and as an indirect fire weapon lobbed over walls. While the basic warhead cannot penetrate Merkava IV armor (thanks to Trophy APS), it remains lethal against personnel and light armor.
Significance
The RPG-7's continued effectiveness after 60 years of proliferation demonstrates why cheap, widely available weapons remain strategically important regardless of the adversary's technological superiority. Israel's Trophy APS was specifically developed in response to RPG threats. The weapon's proliferation means that any future urban combat environment Israel — or any modern military — enters will feature this weapon in abundance.
How the weapons and tactics of Gaza War changed the nature of warfare.
Hamas transformed the Gaza Strip into the world's most extensive militarized underground tunnel system — a network estimated at 500+ km of reinforced shafts, command posts, weapons factories, rocket assembly lines, and storage facilities built 20–40 meters beneath civilian neighborhoods. Tunnel entrances were hidden in homes, mosques, hospitals, and schools. The system was designed to survive Israel's superior air power and serve as a durable base for multi-year armed resistance.
Legacy
The tunnel doctrine fundamentally challenged the assumptions of modern military superiority. Against an enemy that simply goes underground, airpower and precision strikes become largely irrelevant. The IDF was forced to adapt to tunnel warfare — accepting slow, costly ground operations rather than decisive air campaigns. The tunnel system meant that even complete destruction of Gaza's surface structures did not destroy Hamas's military capability. Armies worldwide are now studying and developing countermeasures for this type of infrastructure.
Hamas systematically embedded its military infrastructure — command centers, weapons caches, rocket launch sites, tunnel shafts — inside civilian buildings including Al-Shifa Hospital, Al-Quds Hospital, schools, and residential apartment towers. This was not incidental but doctrinal: by placing military assets alongside civilians, Hamas created a situation where any Israeli strike on military targets would cause civilian casualties and generate international pressure.
Legacy
This doctrine forced a fundamental reexamination of international humanitarian law's distinction between combatants and civilians, and between military and civilian objects. It created a situation where Hamas's military capability was legally and practically shielded by civilian presence, while Israel faced condemnation for every strike regardless of accuracy. The doctrine has since been studied by non-state actors worldwide as a template for asymmetric conflict with military superpowers.
Both sides employed drone technology in unprecedented ways. Israel used quadcopter drones for close-in surveillance of tunnel shafts and building interiors, and Hermes-900 and Heron medium-altitude UAVs for continuous surveillance across the entire Gaza Strip. Hamas employed modified commercial quadcopters dropping grenades on IDF infantry, and acquired anti-tank loitering munitions. Israeli Rotem-L loitering munitions were used for targeted strikes on Hamas commanders.
Legacy
Gaza became a laboratory for drone warfare at the squad and platoon level — a scale not seen in previous conflicts. The commercial quadcopter modified to drop grenades is now the most proliferated tactical drone weapon globally. IDF development of drone-infantry combined tactics — where each infantry squad operated with dedicated surveillance drones — has been adopted or studied by multiple Western militaries.
Hamas's October 7 attack was designed as the trigger for a simultaneous multi-front campaign by the broader 'Axis of Resistance': Hezbollah from Lebanon, Houthis from Yemen, Iranian proxy militias in Iraq and Syria, and potential West Bank uprising. The strategy aimed to stretch Israeli and American military responses across multiple theaters simultaneously, preventing focused force application on any single front.
Legacy
The multi-front strategy partially succeeded: Israel faced active conflict on its northern border for nearly a year, Houthi attacks disrupted global shipping lanes and required US military response, and the West Bank experienced its most violent period in two decades. The strategy demonstrated that non-state actors with regional coordination can complicate even the world's most powerful militaries. It also drove Israel to strike Hezbollah more decisively than in any prior conflict, fundamentally weakening Iran's regional proxy network.
The taking of 250 hostages on October 7 was not incidental to Hamas's strategy — it was a central pillar. Hostages gave Hamas durable diplomatic leverage throughout the war: the ability to offer partial releases in exchange for ceasefires, Palestinian prisoner releases, and humanitarian access. This leverage outlasted Hamas's military capacity and continued operating even after the organization's military and political leadership was largely killed.
Legacy
The hostage strategy proved extraordinarily effective at constraining Israeli military action and maintaining international attention. It forced Qatar, Egypt, and the US into permanent mediation roles, gave Hamas a seat at diplomatic tables it could not otherwise access, and created intense domestic political pressure inside Israel that constrained military decision-making. The strategy will be studied as a template for asymmetric leverage in future conflicts.
