GENTEXT/REMAKS/1. Purpose. This message announces the Fall
Service-wide Cyber Capture the Flag (CTF) competition taking
place from 29 September - 06 November 2026. The Fall event will
be a Cyber Red Zone CTF, focused specifically on Offensive
Cyberspace Operations (OCO). The Deputy Commandant for Information
(DC I), in partnership with the National Cyber Range Complex (NCRC)
under the DOD Test Resource Management Center (TRMC), will organize
a remote CTF event provided through the Joint Information Operations
Range (JIOR). The CTF competition provides a venue where Marine
cyberspace operators can compete in a tailored scenario to complete
cyber challenges of varying difficulty to capture objectives,
referred to as cyber flags. The teams are given 16 hours over a
two-day period to obtain as many cyber flags as possible.
2. Background. These events have provided a venue to foster
camaraderie among the community and opportunities for Marines to
display their keyboard skills in a competitive environment. The
intent of the Marine Corps Cyber Games is ultimately to accelerate
excellence through competition.
3. Action Items. The intended participants for this event are
cyberspace operators from the DCO-IDM Companies and the Cyber
Mission Force. To find an open session, please go to the event
