The Strategic Homeland Intervention Enforcement and Logistics Division, better known by its acronym S.H.I.E.L.D., is a clandestine American military counter-terrorism and intelligence agency.
S.H.I.E.L.D. is subject to oversight by the World Security Council. While this ensures the (grudging) cooperation of most countries, there are still some countries which dislike its interference and have legalized the shooting of any S.H.I.E.L.D. Agents within their borders.
S.H.I.E.L.D. agents are segregated mainly by two categories: clearance levels and fields of expertise. Clearance levels 1 to 6 are widely known within the organization, with the existence of Levels 7 and above being revealed only to the agents within that particular clearance level.
- Victoria Hand - Agent (mission controller(?)), clearance level unknown (presumably Level 8 or above)
- Phil Coulson - Level 8 Field Agent
- Jasper Sitwell - Level 8 Agent
- Melinda May - Level 7 Administrator / Pilot / Combat Specialist
- Grant Ward - Level 7 Combat & Espionage Specialist
- Leo Fitz - Level 5 Engineer
- Jemma Simmons - Level 5 Scientist (Biochemist)
- Natasha Romanoff - Combat & Espionage Specialist, clearance level unknown
- Clinton Barton - Archer / Sniper, clearance level unknown
- Kwan Chen (deceased) - Index Case Agent, clearance level unknown
- Blake (first name unknown) - Agent, clearance level unknown (possibly Level 7 or above)
- Tyler (first name unknown) - Agent, clearance level unknown
- Mack (first name unknown) - Asset Logistics Agent, clearance level unknown
- Akela Amador (pending trial hearing) - former Field Agent, clearance level unknown
- Shaw (first name unknown - Agent (possibly Espionage), clearance level unknown
- Skye (legal identity unknown) - Agent in training, presumably considered to be Coulson's personal responsibility by the organization at large. Currently, not even level 1.
S.H.I.E.L.D. occasionally utilizes the services of civilian experts as Consultants. This may be on a part-time, full-time or project basis. There are only two known S.H.I.E.L.D. Consultants: Tony Stark and Skye. Dr. Erik Selvig might have also been hired in this capacity for Project P.E.G.A.S.U.S., but this has not been explicitly mentioned.
During the events of the Avengers, Dr. Jane Foster was offered a consulting job with S.H.I.E.L.D. as a way to move her covertly to Norway after Loki brainwashed and absconded with her colleague and friend, Eric Selvig. As this "hire" was mostly for her protection (due to her shared knowledge in astrophysics with Selvig), and it is unknown what she was asked to consult for at the Norwegian observatory, S.H.I.E.L.D. might consider this as a protection detail rather than an official consultation.
S.H.I.E.L.D. has a select group of high-level scientists designated as "Assets", whom are given protection around the clock, and constantly moved around covertly so potential enemies cannot extract them from S.H.I.E.L.D. protection and exploit their talents. They occasionally serve as advisers at the S.H.I.E.L.D. Academy. One such Asset was Dr. Franklin Hall.
