when did the military start using dog tags
Dog tag The earliest mention of an identification tag for soldiers comes in Polyaenus (Stratagems 1.17) where the Spartans wrote their names on sticks tied to their left wrists. A type of dog tag ("signaculum"), was given to the Roman legionnaire at the moment of enrollment.[2] The legionnaire "signaculum" was a lead disk with a leather string, worn around the neck,[3] with the name of the recruit and the indication of the legion of which the recruit was part. This procedure, together with enrolment in the list of recruits, was made at the beginning of a four-month probatory period ("probatio"). The recruit got the military status only after the oath of allegiance ("sacramentum"), at the end of "probatio", meaning that from a legal point of view the "signaculum" was given to a subject who was no longer a civilian, but not yet in the military.
Sea Dogs The Sea Dogs were essentially a military branch that were authorized by the Queen to attack the Spanish fleet and loot their ships in order to bring back riches and treasure. The Sea Dogs were able to do this because they carried "Letters of Marque"[2] which made their plundering of Spanish ships legal (in their home country) despite the countries not officially being at war with one another. The Sea Dogs were initially started in 1560 as a way to bridge the gap and close the difference between the Spanish Navy and the English Navy. By having a small fleet of ships that would sail around and pick off Spanish ships, risking their lives and own ships in the process, they were able to reduce the funds and size of the Spanish navy significantly. The Sea Dogs continued carrying out raids against the Spanish until 1604 when England and Spain made peace. After that, many of the Sea Dogs continued as pirates employed by the Barbary States, in what would become the Anglo-Turkish piracy in the Caribbean.[3]
