What is the primary purpose of the Security Forces (SF)?

The primary purpose of the Security Forces (SF) is to provide protective security and law enforcement on military installations. This encompasses a variety of responsibilities essential for maintaining safety and security, such as crime prevention, responding to incidents, and enforcing laws and regulations pertinent to military operations. The Security Forces are tasked with protecting personnel and property, ensuring the readiness and effectiveness of military facilities, and supporting the overall mission of the military by maintaining order and security.

In contrast to other responsibilities, such as providing medical assistance or conducting training programs, the core function of the Security Forces centers on security and law enforcement. While the facilitation of transportation of military equipment is important, it falls outside the specific mandate of the Security Forces and is typically handled by other military units responsible for logistics. Thus, focusing on the security aspect clearly highlights why the correct answer is centered on protective measures and law enforcement duties.
