The Marine Corps Training and Education Command (TECOM) released its Q2 and Q3 FY26 list of newly approved doctrine and training publications. Nine publications were signed between March and June 2026, spanning topics like convoy operations, rear area security, EOD, personnel recovery, and mountain warfare. No publications were archived or cancelled during this period.
Bottom line: Nine doctrine pubs were updated this fiscal year. If your billet, MOS, or training touches any of these topics, check whether your unit is still referencing the old version.
Who it affects
This MARADMIN is addressed to the Total Force, so it applies to SMCR, IMA, and IRR Marines alike. It is most relevant to Marines whose jobs, training, or planning involve any of the nine topic areas listed below. Leaders, S-3s, and instructors running training programs should take note.
What you need to do
Check whether your unit's training materials, SOPs, or course content reference any of the superseded publications listed below. If so, update your references to the new versions.
Most publicly releasable publications are available on the Marine Corps Doctrine website (CAC required):

If you have a CAC but cannot access a publication, scroll to "Can't Find a Publication?" on that site and follow the instructions to request enhanced permissions.
For the publicly releasable publications, you can also access them without a government account on the Marine Corps Publications Electronic Library (MCPEL):

For feedback on any publication, email the appropriate POC listed in the MARADMIN, or send general requests to:
