Total war is warfare that includes any and all civilian-associated resources and infrastructure as legitimate military targets, and typically involves the use of weapons and tactics that result in significant civilian or other non-combatant casualties, whether collateral damage or not. American-English Dictionary defines "total war" as "war that is unrestricted in terms of the weapons used, the territory or combatants involved, or the objectives pursued, especially one in which the laws of war are disregarded." The term can also be applied when the war effort requires significant sacrifices by most of the friendly civilian population.
