COG Call Signs

Each dragon has a unique, four letter identifier that helps distinguish them in battle. If there are dragons who would share the same call sign, then additional letters are added as needed, in this order: A normal example would be T5D, while a longer example could be A30BE5
 * The first letter is the first letter of their name
 * The second number is their Size Class to the nearest 10 (so a 50 foot tall dragon would have a '5')
 * The third letter is their Speed Class
 * The first letter of their registered Dragon Dust scent
 * The number of years, rounded up, of their Spacetime Class

They're usually called out using the NATO phonetic alphabet:

Alfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliet, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu.
