The communications backbone of the entire Army. Signal Soldiers install, operate, and maintain the tactical and strategic communication systems that connect every echelon from the foxhole to the Pentagon.
The 25-Series is the Army's premier communications and information technology force. From satellite terminals to tactical radios, Signal Soldiers ensure that information flows across every battlefield and garrison network.
The 25B Information Technology Specialist is the backbone of the Army's IT infrastructure. 25Bs install, configure, and maintain networks, servers, and workstations.
Operators maintain satellite communication terminals that provide strategic voice and data connectivity globally.
Versatile specialists who maintain and repair the diverse range of communication and digital systems in tactical units.
Operate and maintain the integrated network systems that provide global voice and data connectivity.
The physical connection of the Army. Specialists install and maintain copper and fiber optic networks.
Capture and produce high-quality video and still imagery to document Army operations and missions.
The pinnacle of enlisted Signal leadership. 25Zs manage the entire communications architecture for large units.
Junior enlisted Signal Soldiers begin their career operating and maintaining communications equipment at the company or battalion level. Depending on MOS, they may work a help desk, operate tactical radios, or maintain satellite terminals. Promotion to SPC/E-4 typically occurs within 2-3 years.
This is the time to earn industry certifications (Security+, Network+, CCNA), build technical depth, and establish the foundation for NCO leadership. Signal MOS qualifies soldiers for some of the Army's most marketable technical training.
Signal NCOs lead teams of 3-8 Soldiers responsible for operating and maintaining communication systems. Sergeants (E-5) serve as section chiefs or shift NCOICs in network operations centers, while Staff Sergeants (E-6) lead larger sections and manage network segments.
Completion of BLC (Basic Leader Course) is required for E-5, and ALC (Advanced Leader Course) for E-6. Advanced technical certifications and NCOES completion significantly improve promotion potential.
Senior Signal NCOs represent the most experienced and capable technical leaders in the branch. Sergeants First Class (E-7) serve as S-6 NCOICs or platoon sergeants in Signal companies, Master Sergeants/First Sergeants (E-8) lead at company level, and Sergeants Major (E-9) serve at battalion, brigade, and higher as the 25Z Senior Signal Sergeant.
These positions are highly competitive and board-selected. A record of technical excellence, advanced certifications, NCOES completion, and consistent top-block evaluations are essential.
Experienced Signal NCOs with deep technical expertise can pursue the Warrant Officer track (255-series) or commission as Signal Officers (25A). Warrant Officers serve as the Army's premier Signal technicians — subject matter experts in network engineering, satellite systems, and information services management.
Signal Warrant Officers (255A, 255N) are in high demand across the Army. The OCS or Green-to-Gold path leads to Signal Officer (25A) positions, where prior enlisted experience in network operations provides an enormous advantage in understanding the technical challenges at the tactical level.

Signal Soldiers serve at virtually every Army installation worldwide. Every brigade has a Signal company or S-6 section, making Signal one of the most geographically diverse branches in the Army.
From the tactical TOC to the strategic NOC, Signal Soldiers keep the Army connected. Every commander, every echelon, every mission depends on the 25-Series to get the message through.
Explore Training CoursesThe Army funds Security+, Network+, and A+ exams for Signal Soldiers. Many 25Bs earn Security+ during AIT. These certifications are required for DoD 8570 compliance and translate directly to civilian IT careers.
TCP/IP, subnetting, and routing fundamentals are the backbone of Signal training. Master the OSI model and practice with Packet Tracer before you arrive at Fort Eisenhower. It will pay dividends in AIT.
25S SATCOM operators work with cutting-edge satellite terminals and troposcatter systems. High ASVAB scores and a TS clearance open the door to strategic-level communications assignments.
25B AIT at Fort Eisenhower is 20 weeks. The course covers networking, system administration, and cybersecurity fundamentals. You'll earn CompTIA Security+ before graduation.
25U is tactical radios and field communications — you'll be in the field setting up retrans and programming SINCGARS. 25B is networks and servers — you'll manage infrastructure and troubleshoot systems. Both are in high demand.
Signal skills translate directly to civilian IT and telecom careers. Network admin, systems engineer, SATCOM tech, and cybersecurity analyst roles all map to 25-series experience. The certifications you earn in the Army are industry-standard.
Signal is the Army's most diverse and technically demanding communications career field. If you want industry certifications, hands-on experience with cutting-edge networking and satellite systems, and a direct path to a civilian tech career, the 25-Series is the path. Study networking fundamentals, keep your clearance clean, and never stop learning.
