Answer 2

A Private is a soldier of the lowest military rank (equivalent to Nato Rank Grades OR-1 to OR-3 depending on the force served in). The term dates from the Middle Ages, where privates were known as "private soldiers" (a term used well into the 20th century) who were either hired, conscripted, or feudalized into service by a nobleman forming an army. The usage of Private as a military rank dates from the 18th century, when the army of Napoleon Bonaparte first established the permanent rank of Soldat.
