The IDF introduced a new method of conducting underground warfare, in
preparation for a war with either Hezbollah or Hamas. The method,
which has been developed since the Second Lebanon War and Operation
Cast Lead, is meant to combat the underground tunnel systems used by
Hezbollah in Lebanon and Hamas in the Gaza Strip, which are often used
for weapons transfers and kidnappings. The IDF believes that in
Lebanon, the Hezbollah has dozens of underground bases, from which the
organization operates its rocket launching. Hamas, in the Gaza Strip,
is running a similar underground system. The IDF constructed a tunnel
system designed to simulate those used by terror organizations for
training purposes.
