"Hamas has concluded that it didn't fight in an organized way the last
time," a military source who follows the Islamic regime said. "This is one
of their main lessons."
Hamas has also revised combat tactics and reinforced discipline. The
sources said each commander was granted a defined area of operations and
could not transfer troops to other sectors without authorization from the
General Staff.
"In the last war, Hamas fighters ran wherever they wanted to and nobody
knew what the other was doing," the source said. "This is the way militias
operate, not armies."
Hamas, however, has determined that its asymmetrical strategy of urban
warfare must be bolstered. The sources said Hamas was accelerating
construction of its tunnel network, mining streets and homes to stop an
Israeli infantry advance.
At the same time, Hamas was said to have determined that the use of
improvised explosive devices and tunnels was not exploited during the 2009
war. The sources said Hamas was being trained by Iran's Islamic
Revolutionary Guard Corps and Hizbullah to fight from underground lairs.
