Egyptian border guards discovered a network of 17 underground tunnels with walls of iron 40 cm. thick under the border with Gaza, according to Egyptian security officials.

Israeli Army Trains for Anti-Tunnel Warfare - Barbara Opall-Rome 

[A] massive new IDF urban training base with underground facilities for anti-tunnel warfare is under construction in the Golan Heights.
 
The Snir training base is "a city on top of a city, with all the sophisticated instrumentation and live-fire opportunities needed to train all echelons for all scenarios...on the ground and under the ground," said Ground Forces commander Maj.-Gen. Guy Zur.
 
Units will begin training at the new facility next year...
      
In recent months, Israeli contractors supported by the U.S. Army Corps of Engineers have dug out tunnels designed to replicate the underground labyrinth that Hamas used in the Gaza war in 2014.
