Given a reference text about combat readiness, tell me which troops are kept most ready for combat.

Context:
Combat readiness is a condition of the armed forces and their constituent units and formations, warships, aircraft, weapon systems or other military technology and equipment to perform during combat military operations, or functions consistent with the purpose for which they are organized or designed, or the managing of resources and personnel training in preparation for combat.

Most armed forces maintain varying levels of readiness by the troops to engage in combat due to economic considerations which vary from minutes to months. In modern armed forces troops designated special forces are usually those kept at the highest state of readiness for combat, and are often alerted only a few hours before being committed to combat. Where time is of the essence in military action being initiated, the troops, such as pilots of interceptor aircraft, may be kept in constant state of combat readiness.<|im_end|>
