* Fuel: Tanks typically use diesel fuel, which is a type of hydrocarbon fuel derived from crude oil. Diesel fuel is less volatile than gasoline, meaning it is less likely to catch fire. It also has a higher energy density, meaning it can provide more power per gallon than gasoline.
* Oil: Tanks also use oil to lubricate their engines and other moving parts. Oil helps to reduce friction and wear, and it can also help to cool the engine.
* Coolant: Tanks use coolant to help regulate the engine's temperature. Coolant is typically a mixture of water and antifreeze, and it helps to prevent the engine from overheating.
* Hydraulic fluid: Tanks use hydraulic fluid to power their hydraulic systems. Hydraulic systems are used to move various parts of the tank, such as the turret and the gun.
* Ammunition: Tanks carry a variety of ammunition, including shells, missiles, and machine guns. Shells are typically filled with explosives, while missiles are self-propelled and can be guided to their targets. Machine guns are rapid-fire weapons that can be used to engage enemy infantry.
Aircraft
* Fuel: Aircraft typically use jet fuel, which is a type of hydrocarbon fuel derived from crude oil. Jet fuel is more volatile than diesel fuel, meaning it is more likely to catch fire. However, it also has a higher energy density, meaning it can provide more power per gallon than diesel fuel.
* Oil: Aircraft also use oil to lubricate their engines and other moving parts. Oil helps to reduce friction and wear, and it can also help to cool the engine.
* Coolant: Aircraft use coolant to help regulate the engine's temperature. Coolant is typically a mixture of water and antifreeze, and it helps to prevent the engine from overheating.
* Hydraulic fluid: Aircraft use hydraulic fluid to power their hydraulic systems. Hydraulic systems are used to move various parts of the aircraft, such as the wings, the flaps, and the landing gear.
* Pneumatic fluid: Aircraft use pneumatic fluid to power their pneumatic systems. Pneumatic systems are used to operate various devices on the aircraft, such as the air brakes, the de-icing system, and the pressurization system.
