During the First World War,with the advent of barbed wire and
machine guns gave defense a great advantage,making any offense
operation high cost and effectively useless. This greatly changed
in WWII when tanks and tactical bombers
caused fixed defenses to become by and large ineffective. What
about this present day and age then? Who has the advantage? Offense
or defense? With the wide-spread use of readily available RPGs, has
the offensive power of armoured warfare been blunted?
