Overview

Command and control systems integrators coordinate maintenance personnel and equipment for the installation, repair, maintenance, and modification of Army air defense command and control systems. They develop procedures, troubleshoot data processing, radar, communications, and power equipment, set repair priorities, instruct repair personnel, and advise officers on system capabilities and limitations.

Minimum clearance: Secret

Core Skills

  • Troubleshooting faults escalated by repair personnel
  • Repair prioritization by mission and resources
  • Maintenance procedure development for complex electronics
  • Radar, communications, and power equipment maintenance coordination

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.

Electrical and Electronic Engineering Technologists and Technicians

Hands-on troubleshooting of escalated command and control equipment faults and coordination of radar, communications, and power equipment maintenance transfer directly to electronics maintenance work.

How to prepare: Complete a practical electronics diagnostic exercise using schematics and test equipment, documenting fault isolation, repair, and verification.

What the civilian work involves
  • Modify, maintain, or repair electronics equipment or systems to ensure proper functioning.
  • Set up and operate specialized or standard test equipment to diagnose, test, or analyze the performance of electronic components, assemblies, or systems.
  • Identify and resolve equipment malfunctions, working with manufacturers or field representatives as necessary to procure replacement parts.

Telecommunications Equipment Installers and Repairers, Except Line Installers

Experience coordinating communications equipment installation and repair, resolving difficult faults, and advising repair personnel supports telecommunications equipment service work.

How to prepare: Practice installing and testing a small communications equipment setup, recording circuit faults and post-repair performance against specifications.

What the civilian work involves
  • Test circuits and components of malfunctioning telecommunications equipment to isolate sources of malfunctions, using test meters, circuit diagrams, polarity probes, and other hand tools.
  • Test repaired, newly installed, or updated equipment to ensure that it functions properly and conforms to specifications, using test equipment and observation.
  • Assemble and install communication equipment such as data and telephone communication lines, wiring, switching equipment, wiring frames, power apparatus, computer systems, and networks.
Civilian tools and software (examples)
  • Cisco IOS

Network and Computer Systems Administrators

Troubleshooting command and control data processing and communications equipment provides a foundation for resolving civilian computer and network problems.

How to prepare: Build a Linux and Microsoft Active Directory lab and practice configuration, fault recovery, and backup restoration to develop the software administration skills not documented in the duty evidence.

What the civilian work involves
  • Maintain and administer computer networks and related computing environments, including computer hardware, systems software, applications software, and all configurations.
  • Perform data backups and disaster recovery operations.
  • Diagnose, troubleshoot, and resolve hardware, software, or other network and system problems, and replace defective components when necessary.
Civilian tools and software (examples)
  • Linux
  • Microsoft Active Directory
