What where some weapons used in World War II?
"The backstory of weapons employed in World War 2 on land, sea and air was the intense focus of the scientific /tech communities to create the means for the greatest devastation. Earlier wars may have planted the seeds for lethality, but this new war that engulfed the planet was a quantum leap into the future of weaponry. The reader will hardly forget the game changer: the atomic bomb that made hyperbole an understatement. The weapons were often utilized with a degree of barbaric cruelty and hatred. How else can history explain over 60 million dead? Automation became a standard for what had merely been mechanical. Introduction of full rapid fire required new platforms that created new systems for delivery. The aircraft carrier, the amphibious landing craft, the self propelled gun, the dive bomber became terms common in civilian discourse. Our identification of these weapons into Land, Sea, Air does not limit their use to these broad categories. Many of the systems crossed these boundaries and were employed effectively in all environments." (www.history-of-american-wars.com)
