The Israel Defense Forces (IDF) have exhibited expertise in tunnel warfare, especially in response to threats from terrorist organizations like Hamas and Hezbollah. These groups have historically used tunnels to launch surprise attacks on Israel. The IDF has adapted by investing heavily in intelligence-gathering, employing specialized units and advanced technologies to counter these underground threats. The Israeli Army’s multi-faceted approach makes them a benchmark in tunnel warfare, though challenges persist.
  

Key Points: 

1. Tunnel warfare became a pressing concern for the IDF following its usage by Hezbollah in the 2006 Lebanon War for surprise attacks.
2. The IDF uses a range of techniques and technologies to detect and neutralize tunnels, including ground-penetrating radar, seismic sensors, and specialized robots.
3. Specialized units, such as the Combat Engineering Corps, are pivotal in locating, mapping, and destroying these tunnels, while infantry units undergo rigorous training for operations within tunnels.
4. Advanced surveillance tools like UAVs with thermal imaging enhance the IDF’s real-time situational awareness during tunnel warfare.
5. Despite their advancements, the persistent evolution of terrorist tactics means the IDF must continually innovate and adapt their tunnel warfare strategies.
