Final answer:
Non-commissioned officers may still be authorized to carry ceremonial swords, but the practice is rare and varies depending on the military branch and country.
Step-by-step explanation:
In history, non-commissioned officers were authorized to carry swords in the past, but today the practice is rare and varies depending on the military branch and country. In some cases, certain non-commissioned officers may still be authorized to carry a ceremonial sword as part of their dress uniform, especially during formal occasions or parades.
For example, in the United States Army, the Sergeant Major of the Army is authorized to carry a ceremonial non-commissioned officer's sword as a symbol of their rank and authority.
However, it's important to note that the regulations regarding sword-carrying among non-commissioned officers can change over time, so it is always best to consult the specific military regulations of the country or organization in question.
