a small frontier post.
Cordon lines were set up in the 18th and 19th centuries to cover frontiers in order to stop sabotage detachments and pre-vent smuggling and the spread of epidemic diseases (sanitary cordon). The term “cordon” has been retained in the French Army and several other armies. The term is sometimes also applied to forest ranger posts and posts for the protection of land preserves.
