Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Security Guards

Reconnaissance support and radio net operation transfer to patrol observation and incident communication, with weapons experience relevant to armed posts.

How to prepare: Check your state's guard licensing, training, and background-check process before applying, since most states require licensure. Armed guards usually must also be licensed by the appropriate government authority and face more stringent screening.

What the civilian work involves
  • Patrol industrial or commercial premises to prevent and detect signs of intrusion and ensure security of doors, windows, and gates.
  • Answer alarms and investigate disturbances.

Protective Security Specialist (PSS) | WPSIII

Mounted and dismounted operations, assigned-weapons operation, and radio net communication overlap with mobile armed protection and quick-reaction duties.

How to prepare: Assess whether you can document three years of qualifying protective security experience for this Baghdad opening, such as armed security or designated convoy security for government or government-licensed providers. This opening also requires qualification on the Glock-19, M4, M240, and M249, requalification as required, and maintaining the Physical Readiness Test's 65% performance level.

What the civilian work involves
  • Perform day-to-day personal protective security functions.
  • Participate in advance security preparations.
  • Serve as a member of a QRF as assigned.
