Vietnam Military Lingo Practice Test

Being in-country means you’re physically located inside the country where operations are taking place. In Vietnam War slang, this term marks ground presence on South Vietnamese soil, as opposed to being stationed back in the United States or elsewhere, or merely flying over the area. The other terms refer to something else—Illum is for illumination flares, Huey is a helicopter, and India isn’t the term used for location. So the term that best conveys actual ground presence in South Vietnam is in-country.
