To provide selected Military Occupational Specialty (MOS) 255N Active Army (AA), Reserve Component and National Guard (RC/NG) Warrant Officers with advanced technical training to perform critical MOS individual skill level 2 learning outcomes and tasks in preparation to serve in senior level network management, staff, and supervisory positions.

Course Scope 

Phases 1 and 2 of this course provides instruction and allows practical exercises in Cisco Certified Networking Professional technologies enterprise Core Networking ENCORE (CCNP 1) and Enterprise Advance Routing ENARSI (CCNP 2), SPACE, Advanced Voice over Internet Protocol (VoIP) Collaboration, Quality of Service (QoS), Network Management, and Network Scripting. The course also provides instruction on mandated and directed subjects and topics to include: Signal History, Staff Ride and Battle Analysis (BA).


  • Meet all prerequisites of DA PAM 611-21
  • Complete the 4C-255N (CP) Network Operations Warrant Officer WOBC or 4C-255N (CP) Phase 3
  • Complete the Warrant Officer Advance Course Common Core Distributed Learning (WOAC-CC-DL; ATRRS Course Number 1-250-C32 (DL))
  • Possess a current Top Secret Sensitive Compartmented Information (TS-SCI) security clearance, an Interim TS security clearance or an open T5 investigation

Special Information 

  • This is a two-phase Professional Military Education (PME) MEL Code 6 course attended by both Active Army (AA) and Reserve Component (RC), and National Guard (NG) Soldiers. All phases of the course must be completed in sequence. However, AA and RC/NG attendance requirements are different:
  • The AA students must enroll, attend, and complete all phases of the course in one continuous school attendance period or course iteration.
  • The RC/NG students may enroll, attend, and complete one, two, or both phases in one or more school attendance periods or course iterations. However, the course phases must be completed in sequential order, and the minimum RC/NG attendance period is one complete phase per attendance period or course iteration. This approach will allow RC/NG students an opportunity to return to home station between phases and accommodates the RC/NG training cycle to obtain MEL Code 6 certification within the required two-year timeline.


A capstone training event is conducted at the end of the course to assess student learning and to evaluate their ability to perform required MOS specific critical tasks in a simulated field environment.

Course Structure 

  • This course is structured to be completed in sequence.
  • The course is structured in phases, modules, and lessons.
  • The course consists of two phases comprised of multiple modules. Each module consists of multiple lessons. Phase I consists of 4 modules, and Phase II consists of 6 modules. The description of each phase and module is shown below and in the course map.
  • The course is Commercial Off-the-Shelf (COTS) intensive and reflects the most current information technology, communications equipment, software, hardware, automated data processing (ADP), and methods of data networking, security and information assurance management procedures currently employed within operational units.
