The manual on Field Hygiene and Sanitation is referred to as?

The manual on Field Hygiene and Sanitation is referred to as MCWP 4-11.1. This document specifically addresses the principles and practices involved in maintaining proper hygiene and sanitation in field conditions, which is critical for the health and effectiveness of military personnel. This manual provides guidance on preventing disease and maintaining the overall well-being of individuals in a deployed environment, which is essential for mission readiness.

Other manuals listed, while they may relate to health and safety, do not specifically focus on field hygiene and sanitation in the same way. For instance, NAVMEDCOMINST 6230.2 pertains to immunizations and preventive medicine, OPNAVINST 5100.19 deals with safety and health in general, and NTRP 4-02.21 covers medical department procedures but does not specifically target field hygiene. Therefore, MCWP 4-11.1 is the correct reference for the subject in question.
