s and civilian infrastructure as targets in destroying the enemy's ability to engage in war. There are several reasons for the rise of total warfare in the 19th century. The main one is industrialization. As countries' capital and natural resources grew, it became clear that some forms of warfare demanded more resources than others. Consequently, the greater cost of warfare became evident. An industrialized nation could distinguish and then choose the intensity of warfare that it wished to engage in. Additionally, warfare was becoming more mechanized and required greater

(1853–1856) saw the introduction of trench warfare, long-range artillery, railroads, the telegraph, and the rifle. The mechanized mass-destruction of enemy combatants grew ever more deadly. In WWI (1914–1918) machine-guns, barbed wire, chemical weapons, and land-mines entered the battlefield. The deadly stalemated trench-warfare stage was finally passed with the advent of the modern armored tank late in WWI. One major trend involved the transition away massed infantry fire and human waves to more refined tactics. This became possible with the superseding of earlier weapons like the highly inaccurate

It effectively broke up groups of combatants into smaller more maneuverable units. ''Artillery'' are large guns designed to fire large projectiles a great distance.

at the end of the era. Machine guns were valued for their ability to smash infantry formations, especially attacking enemy formations when they were dense. This, along with effective field artillery, changed tactics drastically.


Static defense

Static defenses evolved from the use of permanent fortifications that were direct descendants of medieval castles. As artillery improved in destructive power and penetrative ability, more modern fortifications were developed, using first thicker layers of stone, then concrete and steel. After naval artillery developed the turret – a moving cannon platform – land fortifications started to use this method as well. Between the World Wars, France built an "impregnable" underground steel and concrete fortification that ran the length of the German-French border. This

Temporary fortifications

As artillery and rifles allowed the killing of enemy personnel at a longer effective range, soldiers started to dig into temporary fortifications. These included massive trenches as used in WWI, and individual soldier-sized "fox holes" which became more common in WWII.


Maneuver warfare

Maneuver had existed throughout military history – from soldiers marching on the field to using horses in cavalry formations. It was not until the advent of mechanized transport over unprepared terrain, such as fields and deserts, using tanks and armored vehicles, that "maneuver warfare" became feasible. First used by the German army in Poland and France in WWII,

Growing tensions of the 1930s restarted the building programs, with even larger ships than before: the Japanese battleship '' Yamato'', launched in 1941, displaced 72,000 tons and mounted guns. This marked the climax of "big gun" warfare, as aircraft would gradually play a larger role in warfare. By the 1960s, battleships had all-but vanished from the fleets of the world.


Aircraft carriers

Though several ships had previously been designed to launch aircraft, the first true "flat-top" carrier was , launched in December 1917. By the start of WWII, aircraft carriers typically carried three types of aircraft:
torpedo bombers A torpedo bomber is a military aircraft designed primarily to attack ships with aerial torpedoes. Torpedo bombers came into existence just before the First World War almost as soon as aircraft were built that were capable of carrying the weight ...

Following WWII, aircraft carriers continued to remain key to navies throughout the latter 20th century, moving in the 1950s to jets launched from Supercarriers, behemoths which could displace as much as 100,000 tons.

This concept was called

Douhet also argued in '' The Command of the Air'' (1921) that future military leaders could avoid falling into bloody World War I-style trench stalemates by using aviation to strike past the enemy's forces directly at their vulnerable civilian population, which Douhet believed would cause these populations to rise up in revolt to stop the bombing.

) developed and maintained a strategic force of bombers that would be able to attack any potential aggressor from bases inside their countries. Before the development of a capable strategic missile force in the Soviet Union, much of the war-fighting doctrine held by western nations revolved around the use of a large number of smaller nuclear weapons used in a tactical role. It is arguable if such use could be considered "limited" however, because it was believed that the US would use their own strategic weapons (mainly bombers at the time) should the USSR deploy any kind of nuclear weapon against civilian targets. A revolution in thinking occurred with the introduction of the
intercontinental ballistic missile An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapo ...
(ICBM), which the Soviet Union first successfully tested in the late 1950s. To deliver a warhead to a target, a missile was far less expensive than a bomber that could do the same job. Moreover, at the time it was impossible to intercept ICBMs due to their high altitude and speed. In the 1960s, another major shift in nuclear doctrine occurred with the development of the submarine-based nuclear missile (SLBM). It was hailed by military theorists as a weapon that would assure a surprise attack would not destroy the capability to retaliate, and therefore would make nuclear war less likely.


The Cold War

Since the end of WWII, no industrial nations have fought such a large, decisive war, due to the availability of weapons that are so destructive that their use would offset the advantages of victory. The fighting of a total war where nuclear weapons are used is something that instead of taking years and the full mobilisation of a country's resources such as in WWII, would take tens of minutes. Such weapons are developed and maintained with relatively modest peace time defence budgets. By the end of the 1950s, the ideological stand-off of the Cold War between the
