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 Since technology and doctrine have changed over time, not all of them are in current use, or they may have been superseded by more modern terms.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.
