Since the earliest recorded military history, scouting and reconnaissance have been key tools employed by military commanders to obtain a picture of the tactical situation and make informed decisions. Scouts known as sciritae were deployed by the Spartans and had a privileged position in their order of battle. The Spartans were so aware of the advantage their scouting operations gave them that they went to great lengths to keep them secret. As military tactics, weapons and equipment developed over the centuries, methods of scouting and reconnaissance evolved and adapted but were never discarded.
