People's Liberation Army's Combat Readiness Levels

The PLA's combat readiness level (中国人民解放军战备等级) is the alert awareness system used by the People's Liberation Army to signal the PRC's combat readiness posture (similar to the American DEFCON system). Different readiness levels activate different set of preparatory actions by the PLA. The system has four levels, with One being the highest (possible war imminent) and Four the lowest. It is the Central Military Commission's responsibility (through the JOCC) to call changes in the readiness level. At different levels, the People's Liberation Army takes different actions to deal with different degrees of emergency.^[1]

China uses other readiness systems, such as the Firefighting Action Readiness^[2] system, and the Militia's three-level readiness system.^[3]^[4]

The PLA's combat readiness system is divided into four levels. Each level has clearly indicated measures and actions of mobilization that the PLA needs to take to face the crisis. The CMC assesses the impact of foreign military activities, and the likelihood of China being attacked.^[5]

Different combat readiness levels may apply only to specific areas, or to specific services and arms of the PLA. In case of localized threats, high levels may apply to a district and not to others.^[1]

The measures or actions required by the PLA's combat readiness level go from very basic, such as conducting combat readiness inspections, strengthening patrols, and maintaining communications open,^[6] to highly strict and urgent measures of mobilization and preparation for shooting war if the emergency is deemed to require it.

Contrary to the DEFCON system, a state of perfect defense normality does not have a readiness number, and level 1 does not imply the near-certainty of shooting war.^[7] The PLA's military doctrine explicitly recommends the use of readiness signalling as a form of deterrence.^[8]

The standard conditions for each of the readiness levels are as follows:^[1]^[5]

PLA Readiness Level	Condition	State	Actions
Readiness Level One (一级战备)	International situation extremely tense. high chance of war breaking out with a foreign power.	Entering War Readiness State.	PLA forces in full alert, on duty 24-hours. Intensify surveillance. Reserve units mobilized. Ordnance placed at the ready. Fortify positions.
Readiness Level Two (二级战备）	International situation intermediately tense. Foreign military operations likely to directly affect China.	Entering War preparation mobilization state.	PLA personnel on-duty overtime. Strengthen Communications. Strengthen Surveillance. Enlarging service units Begin mobilization of reserves. Prepare war materiel at the ready. Establish defensive positions. Conduct combat training.
Readiness Level Three (三级战备)	International situation tense. Foreign military operations may affect China.	Entering combat mobilization state.	All personnel on extra duty, all leave cancelled. Strengthen communications. Carry out surveillance. Restrict traffic into military facilities. Prepare to expand military units. Ready war materiel. Prepare fortified positions.
Readiness Level Four (四级战备)	Large scale military actions by foreign powers. Possibility of it affecting China.	Preserving normal state.	Adjust PLA shifts. Increase preparation inspections. Increase patrols. Strengthen border defenses. Preserve ordinary communications.

The readiness system is not used in situations of complete low international tensions. It can also be raised by steps or by several steps depending on the changing international situation.

History

Since the establishment of the PLA's combat readiness level system, the CRL has been raised several times.

Taiwan Strait Crisis（1996）

In 1995, Republic of China president Li Teng-Hui visited the US in an official capacity. The PRC government decided to carry out two large scale missile test operations around the island of Taiwan to deter any further moves.
