Collateral damageCollateral damage is any death, injury, or other damage inflicted that is an incidental result of an activity. Originally coined by military operations, it is now also used in non-military contexts. Since the development of precision guided munitions in the 1970s, military forces often claim to have gone to great lengths to minimize collateral damage. Critics of use of the term "collateral damage" see it as a euphemism that dehumanizes non-combatants killed or injured during combat, used to reduce the perceived culpability of military leadership in failing to prevent non-combatant casualties.
Urban warfareUrban warfare is warfare in urban areas such as towns and cities. Urban combat differs from combat in the open at both the operational and the tactical levels. Complicating factors in urban warfare include the presence of civilians and the complexity of the urban terrain. Urban combat operations may be conducted to capitalize on strategic or tactical advantages associated with the possession or the control of a particular urban area or to deny these advantages to the enemy.
War in Afghanistan (2001–2021)The War in Afghanistan was an armed conflict from 2001 to 2021. It began when an international military coalition led by the United States launched an invasion of Afghanistan, toppling the Taliban-ruled Islamic Emirate and establishing the internationally recognized Islamic Republic three years later. The conflict ultimately ended with the 2021 Taliban offensive, which overthrew the Islamic Republic, and re-established the Islamic Emirate.
Asymmetric warfareAsymmetric warfare (or asymmetric engagement) is a type of war between belligerents whose relative military power, strategy, or tactics differ significantly. This type of warfare often, but not necessarily, involves insurgents or resistance movement militias who may have the status of unlawful combatants against a standing army. Asymmetrical warfare can also describe a conflict in which belligerents' resources are uneven, and consequently, they both may attempt to exploit each other's relative weaknesses.
Just war theoryThe just war theory (bellum iustum) is a doctrine, also referred to as a tradition, of military ethics that aims to ensure that a war is morally justifiable through a series of criteria, all of which must be met for a war to be considered just. It has been studied by military leaders, theologians, ethicists and policymakers. The criteria are split into two groups: jus ad bellum ("right to go to war") and jus in bello ("right conduct in war").
