170B Electromagnetic Warfare

170B Electromagnetic Warfare Technician

Every radio transmission, radar pulse, and datalink signal is potential terrain in the electromagnetic spectrum. The 170B Electromagnetic Warfare Technician owns that terrain for the Army. This warrant officer plans and executes electromagnetic warfare operations – jamming enemy communications, denying adversary radar use, protecting friendly spectrum, and exploiting the electromagnetic environment for intelligence. In a near-peer conflict where both sides depend on radio and radar to fight, the 170B is the specialist who decides who gets to use the spectrum and who doesn’t.

Warrant officer candidates need a GT score of at least 110 — our ASVAB study guide covers what drives that number.

Job Role and Responsibilities

The 170B Electromagnetic Warfare Technician is the Army’s warrant officer technical expert for electromagnetic warfare (EW) operations, including electronic attack, electronic protection, and electronic warfare support. These warrant officers plan and execute EW missions, advise commanders on spectrum management and electromagnetic spectrum operations (EMSO), integrate EW effects with fires and cyber operations, and manage EW capabilities at brigade and higher echelons. They are the Army’s subject matter expert on the electromagnetic environment (EME) and all activities within it.

Technical Expertise and Scope

The 170B operates across three EW pillars:

  • Electronic Attack (EA): Jamming enemy radar, communications, and datalinks; defeating IED electronic triggers
  • Electronic Protection (EP): Protecting friendly forces from adversary EW; managing friendly spectrum use
  • Electronic Warfare Support (ES): Intercepting, identifying, and locating electromagnetic emissions for intelligence

Their scope extends to:

  • Electromagnetic spectrum management and coordination
  • Spectrum conflict deconfliction between friendly systems
  • Integration of EW effects with joint fires and cyber
  • Counter-IED electronic defeat systems employment
  • EW system operator training and certification

Mission Contribution

Modern military operations depend on radio communications, GPS navigation, and radar for targeting and situational awareness. An adversary can blind, confuse, or disrupt these systems through EW. The 170B gives commanders the capability to do the same to the enemy while protecting their own forces from the same treatment. In a contested electromagnetic environment, the side with better EW integration wins the spectrum fight. The 170B is who makes that happen.

Systems and Tools

The 170B works with Army EW systems including Terrestrial Layer System (TLS), Multi-Function Electronic Warfare (MFEW) systems, electronic support measures equipment, and integrated spectrum management tools. They use the Joint Electromagnetic Spectrum Management Operations (JEMSMO) system and Electronic Warfare Planning and Management Tool (EWPMT) for spectrum coordination.

Salary and Benefits

All pay reflects verified 2026 DFAS rates.

Base Pay at Realistic Career Points

Special Pays and Bonuses

The 170B may qualify for special duty assignment pay for designated EW billets. Retention and accession bonuses have been available for this specialty given its high technical demand. Contact the Warrant Officer Recruiting Command for current bonus status.

Additional Benefits

  • TRICARE Prime: Zero premium healthcare for active-duty warrant officers and families
  • Post-9/11 GI Bill: Full in-state tuition at public universities post-service
  • TSP matching: Up to 5% of base pay under BRS
  • TS/SCI clearance: Significant civilian market value

Work-Life Balance

EW operations are mission-driven – exercises, rotations, and deployments drive the schedule more than garrison duty hours. The 170B advises commanders during operations, which means their schedule follows the operational tempo. Garrison life is more predictable, with regular training and equipment certification cycles.

Qualifications and Eligibility

Appointment Paths

The primary path is enlisted-to-warrant from 29E (Electronic Warfare Specialist) and related CMF 17 and CMF 25 technical MOS. The 170B does not have a civilian direct appointment pathway like 170A and 170D. Prior enlisted experience in electromagnetic warfare or closely related signals intelligence is required.

If you’re a civilian with RF engineering or signals processing background looking to join Army EW, you would need to enlist in a qualifying MOS (29E or CMF 25) first and build operational experience before applying for the warrant officer pathway.

WOCS

All 170B candidates attend the 5-week WOCS at Fort Novosel, Alabama. The school tests leadership and officership – not EW technical skills. The application packet includes: DA Form 61, NCOERs, letters of recommendation, GT score documentation, and commander’s endorsement.

Test Requirements

GT score of 110 is the non-waiverable minimum. No aviation aptitude test (SIFT) required.

Active Duty Service Obligation

170B warrant officers serve a 6-year ADSO following WOBC completion.

See our ASVAB study guide for a study plan focused on the GT composite.

Work Environment

Daily Setting

The 170B works in brigade and battalion S6/EW sections, joint electromagnetic spectrum operations cells (JESOCs), and EW teams at various echelons. Their daily environment includes operations centers with EW planning tools, classified networks, and EW system control interfaces.

In the field, the 170B operates alongside maneuver forces, managing spectrum operations and potentially operating mounted EW systems. Deployed environments range from forward operating bases to joint operations centers.

Position in the Unit

The 170B serves as the EW officer/technician at brigade or division level, advising the commander and S3 on EW operations and spectrum management. They work closely with the S6 on friendly spectrum protection, with the S2 on EW intelligence support, and with fires on EW effects integration.

This warrant officer does not command EW elements – that falls to commissioned cyber/signal officers. The 170B provides technical depth and operational expertise that generalist officers cannot replicate.

Technical vs. Staff Roles

Early career 170Bs spend significant time operating EW systems and developing technical mastery. As they advance, they shift toward staff advisory and planning roles at higher echelons. Senior warrant officers serve as corps-level EW advisors and work in joint EW planning cells at combatant command level.

2-Mile Run (2MR)60
Total300

Medical Standards

Standard Army medical accession and retention standards per AR 40-501. No MOS-specific flight physical required. Hearing conservation is relevant given potential RF exposure in some EW environments.

Deployment and Duty Stations

Deployment Patterns

170B warrant officers deploy with EW-supported formations – brigades, divisions, corps, and joint task forces. EW is in high demand in contested environments. Deployment frequency is moderate, roughly consistent with the unit assignment’s rotation cycle.

Duty Stations

EW billets concentrate at:

  • Fort Eisenhower, GA (Cyber Center of Excellence, primary EW schoolhouse)
  • Fort Hood, TX (Brigade combat teams with organic EW)
  • Fort Campbell, KY
  • Fort Bragg (Fort Liberty), NC (Special Operations)
  • OCONUS: Korea, Germany, select joint commands

Risk, Safety, and Legal Considerations

Job Hazards

EW operations have both physical and legal risk dimensions. Some EW systems transmit high-power RF energy that poses health hazards at close range. Jamming operations can interfere with civilian communications and navigation systems if not carefully managed, creating both legal and operational risks.

EW operations targeting specific adversary systems require clear legal authorities. Spectrum operations in multinational environments require careful coordination to avoid disrupting allied systems.

Safety Protocols

The 170B applies RF safety protocols, operational security requirements, and legal authority frameworks for every EW mission. Spectrum deconfliction with friendly forces is a safety-critical function – EW systems that jam friendly communications can be as damaging as adversary jamming.

Authority and Responsibility

The 170B’s technical authority over EW employment means their recommendations directly shape what operations commanders authorize. Spectrum management decisions affect the entire formation’s communications capability. These are consequential responsibilities requiring precision.

Impact on Family and Personal Life

Family Considerations

Fort Eisenhower (Augusta, GA) has a growing military community following the Cyber/Signal branch consolidation there. The EW community is small – there aren’t many 170B warrant officers in the Army, which creates tight professional bonds but limits duty station options.

Stability

The small EW warrant officer community means positions concentrate at specific locations. Families that plant roots in Augusta, GA or at division installations (Fort Hood, Fort Campbell) find reasonable stability between deployments.

Reserve and National Guard

Component Availability

The 170B has limited availability in the Army Reserve and Army National Guard compared to more common warrant officer specialties. Dedicated EW units exist in some Guard and Reserve formations but the overall position count is smaller.

Appointment Paths

Enlisted-to-warrant from 29E or CMF 17/25 in reserve component units. Reserve WOCS options available. The small community means competition for available warrant officer slots is higher.

Drill and Training Commitment

Standard one weekend per month plus two weeks AT, with additional technical training for EW system proficiency.

Part-Time Pay

At CW3/14 YOS, a drill weekend pays approximately $986 (based on $7,398 monthly / 30 x 4 periods).

Civilian Career Integration

Reserve 170B warrant officers pair well with civilian careers in RF engineering, signals intelligence contracting, spectrum management, and defense electronics. Companies supporting DoD EW programs (Raytheon, L3Harris, Northrop Grumman) actively recruit personnel with hands-on EW operational experience and TS/SCI clearances.

Post-Service Opportunities

Civilian Transition

The 170B’s technical background in EW, signals analysis, and spectrum management transfers to a concentrated set of high-value civilian careers. Defense contractors building and testing EW systems need personnel who understand operational requirements from the inside. Government agencies including NSA, DIA, and NRO hire EW professionals with cleared backgrounds.

Civilian Career Prospects

Is This a Good Job for You? The Right (and Wrong) Fit

Ideal Candidate Profile

Strong 170B candidates are technically oriented EW soldiers who understand both the physics of electromagnetic propagation and the tactical implications of spectrum control. If you’re a 29E who has been thinking about how EW fits into the bigger operational picture – planning EW support rather than just executing it – the warrant officer path is the right move.

RF engineering aptitude, comfort with complex electronic systems, and the ability to explain technical concepts to non-technical commanders are key traits.

Potential Challenges

The 170B community is small. Promotion competition is real, and the position set is limited compared to larger warrant officer specialties. Duty station options are narrower than in more broadly distributed MOS. The civilian pay gap, while real, is smaller than in pure cyber given that EW expertise is harder to find outside of military and cleared defense contractor environments.

Career and Lifestyle Alignment

If you want to be genuinely expert in a technically demanding field that shapes how the Army fights in the electromagnetic domain, the 170B delivers that. The post-service defense contractor market for cleared EW professionals is consistently strong. If you want broader command authority or a more diverse set of assignments, look at commissioned officer paths.
