List of established military terms

This is a list of established military terms which have been in use for at least 50 years. Since technology and doctrine have changed over time, not all of them are in current use, or they may have been superseded by more modern terms. However, they are still in current use in articles about previous military periods. Some of them like camouflet have been adapted to describe modern versions of old techniques.



On landEdit

  • Demilitarized zone (DMZ): Area that is specifically established to be free from military presence or action. Often used to create a buffer between two conflicting states to prevent accidental border skirmishes and established by treaty or a third party peace keeper.
  • No man's land: land that is not occupied or, more specifically, land that is under dispute between countries or areas that will not occupy it because of fear or uncertainty, or for tactical or strategical considerations. No man's land was what the Allied Expeditionary Force under the command of General Pershing would refer to the land separating the fronts of the two opposing armies, as it was deadly to be there.

Arms and servicesEdit

  • Artillery includes any engine used for the discharge of large projectiles.
  • Artillery battery: an organized group of artillery pieces (previously artillery park).
  • Also see below Artillery
