During which conflict were the advancements in Security Forces' training particularly noted?

The advancements in Security Forces' training were particularly noted during the Vietnam War. This period was marked by significant changes in military strategy and tactics, which necessitated an update in force training. The challenges faced in Vietnam, including unconventional warfare and the need for enhanced operational effectiveness in diverse and complex environments, prompted a reevaluation of how security forces were prepared and equipped. As a result, training programs were developed to better prepare personnel for counterinsurgency operations, and a focus was placed on skills such as small unit tactics, mobility, and the use of advanced technologies. This transformation laid the groundwork for modernized training methodologies that continue to influence security forces today.
