The objective of this article is to investigate the impacts of “technology” and“geography”  on  the  variance  of  “offense-defense  balance.”  This  article  starts  bysummarizing the main causal logic: how “technology” and “geography” affect the“Offense-defense Balance.”  It then  offers an  operational definition  and  measuringparameter for each of these concepts and thereafter constructs the causal hypothesesbetween  “technology,”  “geography,”  and  “offense-defense  balance.”  In  total  16cases have been selected for analysis within three following periods: the First WorldWar (1914-1918), the Second World War (1939-1945), and the Six Day War/ YomKippur   War   (1967-1973).   In   conclusion,   a   controlled   comparison   study   isconducted to test the hypotheses. This results in rather positive results being foundin support of the hypotheses;, in other words showing that military technology andgeography  do  indeed  exert  considerable  explanatory  power  on  the  variance  of“offense-defense balance.”
