War effort in the context of "Levée en masse"

In war, civilians are people who are not members of any armed force to the conflict. It is a war crime under the law of armed conflict to deliberately target civilians with military attacks, along with numerous other considerations to minimize civilian casualties during times of war. Civilians engaging in hostilities are considered unlawful combatants, and lose their protection from attack.

A civilian is slightly different from a non-combatant, because some non-combatants are not civilians (for example, people who are not in a military but support war effort or military operations, military chaplains, or military personnel who are serving with a neutral country). Civilians in the territories of a party to an armed conflict are entitled to certain privileges under the customary laws of war and international treaties such as the Fourth Geneva Convention. The privileges that they enjoy under international law depends on whether the conflict is a civil war or an international one.

Tactical bombing is aerial bombing aimed at targets of immediate military value, such as combatants, military installations, or military equipment. This is in contrast to strategic bombing, or attacking enemy cities and factories to cripple future military production and enemy civilians' will to support the war effort, to debilitate the enemy's long-term capacity to wage war. The term "tactical bomber" only refers to a bomber aircraft designed specifically for the primary role of tactical bombing, even though many other types of aircraft ranging from strategic bombers to fighters, interceptors, and helicopters have been used in tactical bombing operations.

Tactical bombing is employed for two primary assignments. Aircraft providing close air support attack targets in nearby proximity to friendly ground forces, acting in direct support of the ground operations (as a "flying artillery"). Air interdiction, by contrast, attacks tactical targets that are distant from or otherwise not in contact with friendly units.

A penal military unit, also known as a penal formation, disciplinary unit, or just penal unit (usually named for their formation and size, such as penal battalion for battalions, penal regiment for regiments, penal company for companies, etc.), is a military formation consisting of convicts mobilized for military service. Such formations may consist of military prisoners convicted under military law, civilian prisoners convicted in civilian courts, prisoners of war who have chosen to side with their captors, or a combination of these groups.

Service in penal military units is generally considered a form of punishment, discipline, or penal labour, used in lieu of, or offered as an alternative to, imprisonment or capital punishment. Penal units have historically been used as disposable cannon fodder, treated poorly or with little regard and used in compromising or dangerous situations (commonly suicide missions such as demining or forlorn hope advance parties), as march battalions that maintain replacement personnel as reserves, or kept in the rear for military operations other than war or menial labour relating to the war effort, guarded and overseen by regular military units, military police, or barrier troops to ensure they do not attempt to escape, retreat, or mutiny. However, this is not always the case: some penal units are treated the same as regular units and, depending on military organization, a dedicated penal unit may not exist at all, with convicts instead being placed in a regular unit. Rewards and incentives for convicts to serve in a penal unit vary—often expungement, commutation, stay of execution, or a pardon—though penal units used as punishment typically lack those by nature.

Friedrich Krupp AG Hoesch-Krupp (formerly Fried. Krupp AG and Friedrich Krupp GmbH), trading as Krupp, was the largest company in Europe at the beginning of the 20th century as well as Germany's premier weapons manufacturer during both world wars. It produced battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities. The company also produced steel used to build railroads in the United States and to cap the Chrysler Building.

After the Nazis seized power in Germany, Krupp supported the regime and was one of many German businesses that profited from slave labor during World War II. Upon the war's end, the head of the company, Alfried Krupp, was tried and convicted as a war criminal for employing prisoners of war, foreign civilians and concentration camp inmates under inhumane conditions in support of the Nazi war effort. Despite being sentenced to imprisonment for twelve years, he served just three and was pardoned (but not acquitted) by John J. McCloy. As a result of this pardon, all of Krupp's holdings were restored.

The Defence of the Realm Act 1914 (4 & 5 Geo. 5. c. 29) (DORA) was an act of the Parliament of the United Kingdom passed on 8 August 1914, four days after the country entered the First World War. It was added to as the war progressed. It gave the government wide-ranging powers during the war, such as the power to requisition buildings or land needed for the war effort, and to make regulations creating criminal offences.

DORA ushered in a variety of authoritarian social control mechanisms, such as censorship:

The United States home front during World War II supported the war effort in many ways, including a wide range of volunteer efforts and submitting to government-managed rationing and price controls. There was a general feeling of agreement that the sacrifices were for the national good during the war.

The labor market changed radically. Peacetime conflicts concerning race and labor took on a special dimension because of the pressure for national unity. The Hollywood film industry was important for propaganda. Every aspect of life from politics to personal savings changed when put on a wartime footing. This was achieved by tens of millions of workers moving from low to high productivity jobs in industrial centers. Millions of students, retirees, housewives, and unemployed moved into the active labor force. The hours they had to work increased dramatically as the time for leisure activities declined sharply.
