Base defense is the cornerstone of successful rear operations. It includes all actions that units
occupying a base take to protect themselves from enemy attack. They consist of a combination of
passive and active measures including: the assistance of the MP patrolling and recon operations;
hardening and disposal actions; cover and concealment; deception; and quick reaction to enemy threat
or attack. Base defense operations are enhanced by the extensive use of reinforcing and natural
obstacles, sensors, surveillance devices, and observation and listening posts.
Base Defense Operations
Every unit must provide for its own local security. It must be capable of protecting itself against Level I
enemy incursions. Support units are not trained or equipped to conduct a sustained defense against
Levels II and III attacks. Therefore, combat support (CS) and combat service support (CSS) units are
normally grouped into bases and base clusters. This will enhance their own defense as well as mutual
support forward forces. The composition of bases and base clusters is the responsibility of the ROC.
The senior officer in each base/base cluster will be the base/base cluster commander.
