Delta Force, officially known as 1st Special Forces Operational Detachment-Delta (1st SFOD-D), is an elite unit of the United States Army. Established in 1977, its primary mission is counter-terrorism, hostage rescue, and high-value target operations. Delta Force members are selected from the military’s most skilled personnel and undergo rigorous training in marksmanship, close-quarters combat, and covert operations. Due to the classified nature of its missions, much of Delta Force’s activities remain undisclosed. In cybersecurity contexts, the term may be used metaphorically to describe elite teams tasked with responding to critical cyber threats or incidents, emphasizing their expertise and specialized skills in high-risk environments.
