BattlecruiserThe battlecruiser (also written as battle cruiser or battle-cruiser) was a type of capital ship of the first half of the 20th century. These were similar in displacement, armament and cost to battleships, but differed in form and balance of attributes.

FirebombingFirebombing is a bombing technique designed to damage a target, generally an urban area, through the use of fire, caused by incendiary devices, rather than from the blast effect of large bombs. In popular usage, any act in which an incendiary device is used to initiate a fire is often described as a "firebombing". Although simple incendiary bombs have been used to destroy buildings since the start of gunpowder warfare, World War I saw the first use of strategic bombing from the air to damage the morale and economy of the enemy, such as the German Zeppelin air raids conducted on London.
Depth chargeA depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive hydraulic shock. Most depth charges use high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater.
ChinditsThe Chindits, officially as Long Range Penetration Groups, were special operations units of the British and Indian armies which saw action in 1943–1944 during the Burma Campaign of World War II.

Total warTotal war is a type of warfare that includes any and all civilian-associated resources and infrastructure as legitimate military targets, mobilises all of the resources of society to fight the war, and gives priority to warfare over non-combatant needs. The term has been defined as "A 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." In the mid-19th century, scholars identified total war as a separate class of warfare.
