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.

First-Line Supervisors of Security Workers

Training and assessing command sentries and security reaction personnel provides directly relevant experience for overseeing civilian security workers.

How to prepare: Build a sample civilian-site training and assessment checklist covering access control, patrols, and alarm response. For positions involving guard duties, most states require licensing with minimum age, background-check, and training conditions; armed guards usually need weapons authorization and face stricter entry requirements.

What the civilian work involves
  • Investigate disturbances on the premises, such as security alarms, altercations, and suspicious activity.
  • Patrol the premises to prevent or detect intrusion, protect property, or preserve order.
  • Monitor and authorize entry of employees, visitors, or other persons.
Civilian tools and software (examples)
  • Microsoft Office software

Security Managers

Serving as the Command Antiterrorism Officer's primary assistant and assessing security personnel provides a foundation for coordinating civilian protective activities.

How to prepare: Develop a sample site-security operations budget to address the financial responsibilities beyond the verified military duties.

What the civilian work involves
  • Develop budgets for security operations.
  • Plan, direct, or coordinate security activities to safeguard company employees, guests, or others on company property.
  • Direct or participate in emergency management and contingency planning.
Civilian tools and software (examples)
  • Microsoft Excel
