What are the Marine Corps Service Charlie uniform?

Answer 1

The short sleeve khaki shirt with appropriate service trousers or skirt/slacks is designated as the service "C" uniform. During the winter season, commanders may, at their discretion, when the weather requires, authorize the service "C" uniform. This uniform may be worn as a uniform of the day and for leave or liberty, unless otherwise prescribed by the commander, and may be prescribed for formations at parades or ceremonies on and off the military activity. This uniform will not be worn for formal or semiformal social events. The green V-neck service sweater may be worn only as part of the service "B" uniform at the option of the individual. It will not be worn on those occasions when the wear of the service coat would be more appropriate. It may be worn as part of the duty uniform both on and off the military installation, for commuting to and from work, and on leave and liberty. It will not be worn for inspections, ceremonial formations, or parades.

The United States Marine Corps has very strict uniform regulations. These include keeping all uniforms clean and pressed and positioning pins in the appropriate locations.
