Sierra One is a common radio call sign used to refer to the leader or commander of a special operations aviation unit. It indicates that the speaker is the commander of the aviation element during a mission. The term is widely used among military special operations forces, particularly in the United States.
Origins and Meaning
The term Sierra One has its origins in the NATO phonetic alphabet, which assigns code words to letters to ensure clarity of voice communications. The word “Sierra” represents the letter “S” and “One” refers to the number 1. Put together, Sierra One translates to S1, which is short for Special Operations Aviation Unit Commander or Mission Commander.
Some key points about the meaning and usage of Sierra One:
– It refers specifically to the aviation commander in a special operations mission, not the overall ground force commander.
– It is used as a call sign over communications networks to identify the leader of the aviation team.
– It indicates that the speaker is in charge of planning and executing the aviation aspects of the mission.
– The term is commonly used in military organizations such as the U.S. Army’s 160th Special Operations Aviation Regiment as well as joint special operations task forces.
– It represents a leadership position, with the Sierra One commander directing insertion/extraction of ground troops by helicopter and providing air support.
– The commander denoted by Sierra One may be a rated aviator piloting one of the aircraft or leading from the ground as the aviation mission commander.
– Sierra One call signs are unique to special operations aviation units and not used by conventional aviation forces.
Usage in Different Military Units
While Sierra One is a widely used term, its specific usage varies slightly across different special operations units:
U.S. Army 160th SOAR: Sierra One indicates the aviation mission commander, typically a senior Warrant Officer. All aircraft commanders in the 160th SOAR use the Sierra call sign prefix.
U.S. Air Force Special Operations: Sierra One often refers to the most senior ranked commander in the aviation element, not necessarily the mission commander.
U.S. Naval Special Warfare: Sierra One refers to the senior aviator during NSW missions. He may be on the ground or piloting the lead aircraft.
Joint Special Operations: During joint missions involving multiple service branches, Sierra One is reserved for the overall aviation mission commander, regardless of service affiliation.
Though the exact context differs, Sierra One always refers to the senior aviation commander directing special operations aviation forces during a mission. It represents a position of leadership and authority.
When Would Sierra One Be Used?
Sierra One call signs come into play during the conduct of actual special operations missions requiring aviation support. Key situations where Sierra One would be actively used include:
– Infiltrating and exfiltrating special operations ground forces via helicopter. For example, inserting Navy SEALs behind enemy lines or extracting Army Special Forces ODA teams after a raid.
– Providing close air support to special ops ground troops engaged in combat. The Sierra One commander would direct the attack helicopters and gunships supporting the ground element.
– Conducting sensitive special operations aviation missions such as flying covert surveillance drones or transporting elite hostage rescue units.
– Leading classified aviation elements of joint special ops raids to capture or eliminate high-value targets.
– Coordinating aviation operations as part of global counterterrorism missions.
