GENTEXT/REMARKS/1.  Purpose.  The purpose of this MARADMIN is to 
solicit nominees to attend Fiscal Year (FY) 2026 basic and advanced
space operations courses.  The National Security Space Institute 
(NSSI) courses pertaining to this solicitation are Space 200 and 
Space 300.  Space 200 is a two-week academic course designed to 
provide introductory training for mid-grade officers, enlisted, and
civilian personnel to gain knowledge and develop skills required to 
integrate space-related capabilities into combat operations.  Space 
200 is the primary training for billets with the Free Military 
Occupational Specialty (FMOS) 1786, Space Operations Staff Officer. 
Per reference C, only Commissioned Officers (LtCol to 2ndLt) are 
eligible for the 1786 FMOS.
2.  Background.  Department of Defense (DoD) implemented a space 
professional strategy in order to grow and maintain cognizance and 
expertise in the space domain.  In accordance with references A 
through C, the Marine Corps maintains a cadre of space professionals
to support Marine Corps equities in space and to ensure that 
space-based capabilities are leveraged to the maximum extent 
possible in support of Fleet Marine Force (FMF) commanders’ 
objectives.  Advanced space education is vital to maintaining a 
relevant Space Cadre.  Thus, Headquarters Marine Corps, Deputy 
Commandant for Information (HQMC DC I) provides information on space
training opportunities and serves as a liaison to NSSI for 
attendance to these courses. 
3. Course Information.
3.a.  Space 200:  Two weeks (10 training days). Marines selected to 
attend Space 200 will analyze the impact of space mission areas in 
support of joint and coalition operations and analyze the impact of 
offensive and defensive space control capabilities on joint and 
coalition forces.  Topics include:  principles of systems 
engineering fundamentals; operational risk assessment; economic, 
political, and military impacts; competing space and counterspace 
capabilities; positioning, navigation, and timing; navigation 
warfare; use of the GPS Interference and Navigation Tool; adversary 
intelligence, surveillance, and reconnaissance capabilities; missile
warning; and space and cyberspace threats. 
3.a.1.  Space 300:  Three weeks (15 training days).  Marines 
selected to attend Space 300 will analyze National and DoD 
space-related acquisitions, policy, strategy, doctrine, and 
international and domestic law while considering space power 
contributions to national security.  Topics include:  space law, 
space policy, geopolitical foundations, space doctrine, and 
integration of space into operational scenarios.
3.a.2.  Additional course information can be found on the NSSI 
website:  https:(slash)(slash)nssi.spaceforce.mil/
