Maps, RPGs and Clothes for a Long Stay in a Lebanese Tunnel

The Israel Defense Forces released an account of an encounter in southern Lebanon in which a Hezbollah fighter emerged from an underground tunnel in front of troops of the 401st Armoured Brigade combat team and was killed at close range. According to the IDF statement, the soldiers returned fire and neutralised the man, and there were no casualties among Israeli forces.

Afterwards, the statement said, brigade troops together with Yahalom (the special engineering unit of the IDF's Combat Engineering Corps) scanned the area and located the tunnel the fighter had come out of. Inside the compound they found maps and weaponry of various kinds, including rocket-propelled grenade rounds, and clothing intended for prolonged stays. The military said it would continue to act against Hezbollah, which it described as operating under the auspices of the Iranian regime, and would not allow harm to Israeli civilians.

Why a tank brigade is clearing tunnels

The 401st is one of the IDF's armoured brigades, nicknamed “Iron Tracks”, and is listed among the formations of the 162nd Division in a reference profile of that division. In practice its recent work in Lebanon has looked less like tank warfare than like ground clearance. JNS reported in August 2026 that the brigade had completed an eight-month deployment in southern Lebanon during which it destroyed more than 1,200 Hezbollah sites, seized over 600 weapons, killed more than 60 fighters and dismantled tunnels running hundreds of metres.

Yahalom, the unit sent down the shafts

Yahalom is the Combat Engineering Corps' specialist unit for underground warfare, explosives and demolition, and it is the formation the IDF sends when a tunnel entrance has to be found, mapped and cleared. Its role was set out in detail by the Jerusalem Post in April 2026, in an account of the destruction of what the IDF called the largest Hezbollah tunnel complex in southern Lebanon: Yahalom needed more than a week simply to find and fully map the network’s entrances, even though the military said it had known of the tunnel’s existence since 2024.

What is underneath southern Lebanon

That complex, near Kantara, ran roughly two kilometres in length across a band about ten kilometres wide, with sections more than 25 metres deep and a parallel eastern network the IDF believed Hezbollah intended to join up. The military said it found evidence of Iranian funding and design, and Iranian-made weapons inside, and assessed that the network could have housed and supplied thousands of fighters from Hezbollah's Radwan force, according to the same Jerusalem Post report. Items of the kind the 401st found (maps and clothing for extended stays) fit that picture of tunnels built to be lived in rather than passed through.

The fighting the brigade was part of resumed on 2 March 2026, when Hezbollah began firing across the border again and Israel moved troops into southern Lebanon, according to a timeline of the 2026 Lebanon war.

What is still unclear

The IDF statement gives no date and no location for the encounter beyond “southern Lebanon”, and no count of the weapons recovered. It does not say whether the tunnel was destroyed, whether anyone else was inside it, or how the fighter came to be alone. It also does not identify the man, and the account has not been independently verified.
