Hezbollah: What weapons does it have? A visual guide

Hezbollah is believed to be the most heavily armed non-state group in the world. Backed by Iran and based in the eastern Mediterranean country of Lebanon, the Shia Islamist group has been engaged in confrontations with Israeli forces on Lebanon’s southern border since October 8.

The cross-border hostilities have raised the specter of a regional conflagration and prompted intense diplomatic efforts to de-escalate tensions. Though no match for Israel’s military might, Hezbollah’s increasingly sophisticated arsenal has the potential to inflict significant damage on Israel and its allies in the region.

Israel would also have to contend with Hezbollah’s strategic depth. The group is part of an Iran-led axis of militants spanning Yemen, Syria, Gaza and Iraq. Some of these groups have increased coordination significantly since October, when Israel launched a war in Gaza after Hamas-led militants attacked the country. This axis is known in Israel as the “ring of fire.”

Over the course of the past ten months, Hezbollah’s partners in the region have been engaged in a simmering conflict with Israel and its allies. Yemen’s Houthis have sporadically fired at vessels in the Red Sea, an artery of global trade, as well as on Israel. Islamic Resistance in Iraq, an umbrella group of hardline Shia factions, has also launched attacks on US positions in that country. The axis has conditioned the cessation of those hostilities on a ceasefire in Gaza, rebranding themselves as a “supportive front” for Palestinians in Gaza, as described by a senior Hezbollah leader.

Hezbollah’s fighting force emerged from the rubble of Israel’s 1982 invasion of Beirut. At the time, it was a rag-tag group of Islamist fighters supported by Iran’s fledgling Islamic Republic. This was followed by a meteoric rise in the group’s military and political might. In 2000, its guerrilla fighters forced Israeli forces to withdraw from south Lebanon, ending a more-than-20-year occupation. In 2006, it survived a 34-day war with Israel that wreaked havoc on Lebanon.

During Syria’s uprising-turned-civil war in the 2010s, it fought on behalf of Syrian President Bashar al-Assad as he brutally quashed armed opposition forces and inflicted a huge civilian death toll. As it fought in the trenches of that nearly decade-long war, Hezbollah became seasoned in urban warfare and solidified its alliances with other Iran-backed groups fighting in Syria. It also cleared a vital supply route for weapons between Iran and Lebanon, via its partners in Iraq and Syria, further bolstering its arsenal.

Throughout its decades-long conflict with Israel, Hezbollah has been engaged in asymmetric warfare. It has sought to grow its political and military might, while seeking to establish deterrence despite Israel’s military superiority.

But Hezbollah threads the needle carefully. Provoking Israel’s full firepower could significantly degrade the group’s capabilities, setting it back years – if not decades – and destroying large parts of Lebanon, which has buckled under the weight of its years-long financial crisis.

The group has already lost more than 400 fighters, including commanders, in border confrontations with Israel since October. Around 150 civilians have been killed in Israeli strikes, according to CNN’s analysis of publicly available figures. The impact on Israel has also been considerable, with over 60,000 people displaced from its northern border area, and scores killed, including soldiers and civilians.

As the confrontations at the border continue, Hezbollah has sought, with some success, to undermine Israel’s vaunted missile defense system known as the Iron Dome. It has tried to do so by attacking its platforms and overwhelming it with swarms of drones and short-range missiles in order to open a path for other projectiles to reach deeper into Israeli territory.

Hezbollah’s chances of survival in an all-out war with Israel is hinged on whether or not it can outsmart these systems which have in recent months intercepted thousands of airborne weapons from Iran, Gaza and Lebanon.

Because of Hezbollah’s growing power, a possible all-out war between Israel and Lebanon would thrust the Middle East into uncharted waters. The diplomatic effort to prevent it is likely to continue at a breathless pace.
