Dog tag
"Dog tag" is an informal but common term for a specific type of identification tag worn by military personnel. The tags' primary use is for the identification of casualties; as such, they have information about the personnel written on them, and convey essential basic medical information such as their blood type and history of inoculations. They often indicate religious preference as well.
Dog tags are usually fabricated from a corrosion-resistant metal. They commonly contain two copies of the information, either in the form of a single tag that can be broken in half, or as two identical tags on the same chain. This purposeful duplication allows one tag, or half-tag, to be collected from a personnel's dead body for notification, while the duplicate remains with the corpse if the conditions of battle prevent it from being immediately recovered. The term arose and became popular because of the tags' resemblance to animal registration tags.
History
The earliest mention of an identification tag for soldiers comes in Polyaenus where the Spartans wrote their names on sticks tied to their left wrists. A type of dog tag was given to the Roman legionary at the moment of enrollment. The legionary "signaculum" was a lead disk with a leather string, worn around the neck, with the name of the recruit and the indication of the legion of which the recruit was part. This procedure, together with enrollment in the list of recruits, was made at the beginning of a four-month probatory period. The recruit got the military status only after the oath of allegiance 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.In more recent times, dog tags were provided to Chinese soldiers as early as the mid-19th century. During the Taiping revolt, both the Imperialists and those Taiping rebels wearing a uniform wore a wooden dog tag at the belt, bearing the soldier's name, age, birthplace, unit, and date of enlistment.
American Civil War
During the American Civil War from 1861–1865, some soldiers pinned paper notes with their name and home address to the backs of their coats. Other soldiers stenciled identification on their knapsacks or scratched it in the soft lead backing of their army belt buckle.Manufacturers of identification badges recognized a market and began advertising in periodicals. Their pins were usually shaped to suggest a branch of service, and engraved with the soldier's name and unit. Machine-stamped tags were also made of brass or lead with a hole and usually had an eagle or shield, and such phrases as "War for the Union" or "Liberty, Union, and Equality". The other side had the soldier's name and unit, and sometimes a list of battles in which he had participated.
Franco-Prussian War
On a volunteer basis Prussian soldiers had decided to wear identification tags in the Austro-Prussian War of 1866. However, many rejected dog tags as a bad omen for their lives. So until eight months after the Battle of Königgrätz, with almost 8,900 Prussian casualties, only 429 of them could be identified. With the formation of the North German Confederation in 1867 Prussian military regulations became binding for the militaries of all North German member states. With the Prussian Instruktion über das Sanitätswesen der Armee im Felde issued on 29 April 1869 the identification tags were obligatorily to be handed out to each soldier before marching afield. The Prussian Army issued identification tags for its troops at the beginning of the Franco-Prussian War in 1870. They were nicknamed Hundemarken and compared to a similar identification system instituted by the dog licence fee, adding tags to collars of those dogs whose owners paid the fee, in the Prussian capital city of Berlin at around the same time period.World War I
The British Army introduced identity discs in place of identity cards in 1907, in the form of aluminium discs, typically made at regimental depots using machines similar to those common at fun fairs, the details being pressed into the thin metal one letter at a time.Army Order 287 of September 1916 required the British Army provide all soldiers with two official tags, both made of vulcanised asbestos fibre carrying identical details, again impressed one character at a time. The first tag, an octagonal green disc, was attached to a long cord around the neck. The second tag, a circular red disc, was threaded on a 6-inch cord suspended from the first tag. The first tag was intended to remain on the body for future identification, while the second tag could be taken to record the death.
British and Empire/Commonwealth forces were issued essentially identical identification discs of basic pattern during the Great War, Second World War and Korea, though official identity discs were frequently supplemented by private-purchase items such as identity bracelets, particularly favoured by sailors who rightly believed the official discs were unlikely to survive long immersion in water.
The U.S. Army first authorized identification tags in War Department General Order No. 204, dated December 20, 1906, which essentially prescribes the Kennedy identification tag:
The U.S. Army changed regulations on July 6, 1916, so that all soldiers were issued two tags: one to stay with the body and the other to go to the person in charge of the burial for record-keeping purposes. In 1918, the U.S. Army adopted and allotted the service number system, and name and service numbers were ordered stamped on the identification tags.
World War II "notched" tags
There is a recurring myth about the notch situated in one end of the dog tags issued to United States Army personnel during World War II, and up until the Vietnam War era. It was rumored that the notch's purpose was that, if a soldier found one of his comrades on the battlefield, he could take one tag to the commanding officer and stick the other between the teeth of the soldier to ensure that the tag would remain with the body and be identified.In reality, the notch was used with the Model 70 Addressograph Hand Identification Imprinting Machine. American dogtags of the 1930s through 1980s were produced using a Graphotype machine, in which characters are debossed into metal plates. Some tags are still debossed, using earlier equipment, and some are embossed on computer-controlled equipment.
In the Graphotype process, commonly used commercially from the early 1900s through the 1980s, a debossing machine was used to stamp characters into metal plates; the plates could then be used to repetitively stamp such things as addresses onto paper in the same way that a typewriter functions, except that a single stroke of the printer could produce a block of text, rather than requiring each character to be printed individually. The debossing process creates durable, easily legible metal plates, well-suited for military identification tags, leading to adoption of the system by the American military. It was also realized that debossed tags can function the same way the original Graphotype plates do.
The Model 70 took advantage of this fact, and was intended to rapidly print all of the information from a soldier's dogtag directly onto medical and personnel forms, with a single squeeze of the trigger. However, this requires that the tag being inserted with the proper orientation, and it was believed that battlefield stress could lead to errors. To force proper orientation of the tags, the tags are produced with a notch, and there is a locator tab inside the Model 70 which prevents the printer from operating if the tag is inserted with the notch in the wrong place.
This feature was not as useful in the field as had been hoped, however, due to adverse conditions such as weather, dirt and dust, water, etc. In addition, the Model 70 resembled a pistol, thus attracting the attention of snipers. As a result, use of the Model 70 hand imprinter by field medics was rapidly abandoned, and eventually the specification that tags include the locator notch was removed from production orders. Existing stocks of tags were used until depleted, and in the 1960s it was not uncommon for a soldier to be issued one tag with the notch and one tag without. Notched tags are still in production, to satisfy the needs of hobbyists, film production, etc., while the Model 70 imprinter has become a rare collector's item.
It appears instructions that would confirm the notch's mythical use were issued at least unofficially by the Graves Registration Service during the Vietnam War to Army troops headed overseas.
Dog tags are traditionally part of the makeshift battlefield memorials soldiers created for their fallen comrades. The casualty's rifle with bayonet affixed is stood vertically atop the empty boots, with the helmet over the rifle's stock. The dog tags hang from the rifle's handle or trigger guard.
Non-military usage
Medical condition identification
Some tags are used also by civilians to identify their wearers and specify them as having health problems that may' suddenly incapacitate their wearers and render them incapable of providing treatment guidance and/or
' interact adversely with medical treatments, especially standard or "first-line" ones and/or
' provide in case of emergency contact information and/or
' state a religious, moral, or other objection to artificial resuscitation, if a first responder attempts to administer such treatment when the wearer is non-responsive and thus unable to warn against doing so. A DNR signed by a physician is still required in some states.
Military personnel in some jurisdictions may wear a supplementary medical information tag.
Fashion
Dog tags have recently found their way into youth fashion by way of military chic. Originally worn as a part of a military uniform by youth wishing to present a tough or militaristic image, dog tags have since seeped out into wider fashion circles. They may be inscribed with a person's details, their beliefs or tastes, a favorite quote, or may bear the name or logo of a band or performer.Since the late 1990s, custom dog tags have been fashionable amongst musicians, and as a marketing give-away item. Numerous companies offer customers the opportunity to create their own personalized dog tags with their own photos, logos, and text. Even high-end jewelers have featured gold and silver dog tags encrusted with diamonds and other jewels.
Variations by country
Austria
The Austrian Bundesheer used a single long, rectangular tag, with oval ends, stamped with blood group & Rh factor at the end, with ID number underneath. Two slots and a hole stamped beneath the nunicew the tag to be broken in half, and the long bottom portion has both the ID number and a series of holes which allows the tag to be inserted into a dosimeter. This has been replaced with a more conventional, wider and rounded rectangle which can still be halved, but lacks the dosimeter reading holes.Australia

In 2009, Danish dog tags were discontinued for conscripts.
East Germany
The Nationale Volksarmee used a tag nearly identical to that used by both the Wehrmacht and the West German Bundeswehr. The oval aluminum tag was stamped "DDR" above the personal ID number; this information was repeated on the bottom half, which was intended to be broken off in case of death. Oddly, the tag was not worn, but required to be kept in a plastic sleeve in the back of the WDA identity booklet.Ecuador

Poland
In 1928, a new type of dog tag was proposed by gen. bryg. Stanisław Rouppert, Poland's representative at the International Red Cross. It was slightly modified and adopted in 1931 under the name of Nieśmiertelnik wz. 1931. The new design consisted of an oval piece of metal, roughly 40 by 50 millimeters. There were two notches on both sides of the tag, as well as two rectangular holes in the middle to allow for easier breaking of the tag in two halves. The halves contained the same set of data and were identical, except the upper half had two holes for a string or twine to go through. The data stamped on the dog tag from 2008 included:

During World War One and Two, service personnel were issued pressed fibre identity disks, one green octagonal shaped disc, and a red round disc. The identity disks were hand stamped with the surname, initials, service number and religion of the holder and if in the Royal Air Force, the initials RAF. The disks were worn around the neck on a 38" length of cotton cord, this was often replaced by the wearer with a leather bootlace. One tag was suspended below the main tag.
The fibre identity disks in the RAF were still in use in 1999.
From 1960 these were replaced with stainless steel ID tags on a green nylon cord, two circular and one oval. The oval was withdrawn around 1990.
United States
Tags are properly known as identification tags; the term "dog tags" has never been used in regulations.A persistent rumor is that debossed dog tags were issued from World War II till the end of the Vietnam War and that currently the U.S. Armed Forces is issuing embossed dog tags. In actuality, the U.S. Armed Forces issues dog tags with both types of imprinting, depending on the machine used at a given facility. The military issued 95% of their identification tags up until recently with debossed text.
The U.S. Armed Forces typically carry two identical oval dog tags containing:
;U.S. Air Force
- Last name, first name, middle initial
- Social Security number, followed by "AF" indicating branch of service
- Blood Group
- "blank"
- Religion
- Last name
- First name and middle initial
- Social Security number, followed by "AF" indicating branch of service
- Blood Group
- Religion
- Last name
- First and middle initials and suffix; blood group

- Branch ; Gas mask size
- Religious preference, or medical allergy if red medical tag

- Religion
- Last name
- First name middle initial
- Dept of Defense ID Number
- Blood type

- Last name, first name, middle initial
- Social Security number, no dashes or spaces, followed immediately by branch
- Blood group
- Religion
Religious designation
By the time of the Vietnam War, some IDs spelled out the broad religious choices such as PROTESTANT and CATHOLIC, rather than using initials, and also began to show individual denominations such as "METHODIST" or "BAPTIST." Tags did vary by service, however, such as the use of "CATH," not "CATHOLIC" on some Navy tags. For those with no religious affiliation and those who chose not to list an affiliation, either the space for religion was left blank or the words "NO PREFERENCE" or "NO RELIGIOUS PREF" were included.
Although American dog tags currently include the recipient's religion as a way of ensuring that religious needs will be met, some personnel have them reissued without religious affiliation listed—or keep two sets, one with the designation and one without—out of fear that identification as a member of a particular religion could increase the danger to their welfare or their lives if they fell into enemy hands. Some Jewish personnel avoided flying over German lines during WWII with ID tags that indicated their religion, and some Jewish personnel avoid the religious designation today out of concern that they could be captured by extremists who are anti-Semitic. Additionally, when American troops were first sent to Saudi Arabia during the Gulf War there were allegations that some U.S. military authorities were pressuring Jewish military personnel to avoid listing their religions on their ID tags.
