MCWP 4-11.1 - Health Service Support Operations

Scope

MCWP 4-11.1 covers Health Service Support (HSS) operations across Marine Corps forces. The publication frames HSS as the operational discipline supporting commanders with medical capability, casualty care, and force health protection. The portal originally filed this topic as a generic "MCO 6000" stub. No HQMC order carries the number. The Marine Corps doctrine for Health Service Support lives in the MCWP series. The "MCO 6000" alias preserves back-compat for any inline reference written before the renumber.

Audience

Commanders and their staffs assessing HSS capabilities and requirements as part of mission planning. Medical personnel assigned to Marine Corps forces responsible for casualty response and force health protection. S-1 sections tracking medical readiness data feeding the commander's oversight picture.

Status

Signed 2012-12-10 per this entry's effective date. Repo evidence for this publication is limited to the oversight matrix row, the FA registry entry, and the MCO 6320.4 companion note. Caution. The oversight matrix action statements are IGMC FAC summaries awaiting a source-text walk, so confirm the 90 percent medical readiness figure and the CSIB requirement against the publication and the FA 6000 checklist before treating them as authoritative.
