List of oldest military units and formations in continuous operation
This is a list of oldest military units and formations in continuous operation. In continuous operation here means not units that no longer exist, or recent creations sharing only the name with an older unit.
Please note: Whereas modern standing armies first developed in the 15th century, the defining terminology for contemporary military units and formations, such as company, battalion, regiment etc. mostly arose in the early modern period, during the 16th and 17th centuries.
