Agents of STRIKE
SHIELD classifies security clearance using a level structure, from 1-10, with each increasing level representing increased access and knowledge to intelligence, information, and operational details of the agency.
Level 0: The general public, anyone outside SHIELD. Until the 1990s, people at Level 0 were not even aware of the extranormal phenomenon or SHIELD’s existence.
Level 1: Support staff. The clearance level for reception and custodial staff at SHIELD facilities, and civilian staff at SHIELD-affiliated bureaucratic offices.
Level 2: Maintenance staff, such as mechanics and civilian engineering contractors. Anyone who needs access to the inside of SHIELD facilities will have at least this clearance level, unless being escorted by someone senior.
Level 3: Junior research staff (SCI-TECH), field agents in training (OPS), nurses and medical technicians (MED), low-priority signal analysts (COMMS), low-security guards (SEC)
Level 4: Research staff (SCI-TECH), field agents (OPS), doctors and medical researchers (MED), signal analysts and intrusion specialists (COMMS), medium-security guards and junior IA investigators (SEC)
Level 5: Senior research staff (SCI-TECH), senior field agents (OPS), surgeons and chief senior medical researchers (MED), senior analysts (COMMS), high-security guards and IA investigators (SEC)
Level 6: Project leads (SCI-TECH), field agent team leads (OPS), medical advisory commitee members (MED), regional monitors (COMMS), Avengers (except for Hawkeye and Black Widow)
