The units in World in Conflict all have various special features. Most units have special offensive abilities which recharge after use. Examples include standard infantry with grenade launcher attack, medium tanks with fragmentation shells, heavy (main battle) tanks with HEAT shells, medium attack helicopters with anti-aircraft missiles, heavy attack helicopters with anti-tank missiles, medium artillery (mortars) with white phosphorus shells, and heavy artillery (howitzers, rocket launchers) with smoke screen shells. In addition, most units also have a defensive ability. For example, infantry are capable of sprinting, tanks can utilise smoke screens, and helicopters are equipped with countermeasures. Some defensive abilities, such as smoke screens, may be a hindrance as well as a help by allowing a unit to remain hidden but at the same time also clouding its own view.
