Step-by-step explanation:
The Marine Operational Stress Surveillance and Training (MOSST) program is specifically designed to provide education, support, and health assessments for Marine personnel during their deployment cycle. This program does not cater to the Army, Navy, or Air Force personnel but is targeted solely at those serving in the Marine Corps. It is part of the broader system of healthcare and preparedness that supports the U.S. armed forces, ensuring that Marines are physically and mentally ready to face the challenges of their service, including the rigors of training and the possibility of encountering combat situations, as implied by the historical context of Operation Desert Storm where chemical warfare was a concern.
