To get "dd" from 215, you can interpret "dd" as a representation of a number in base 10. In the context of base 4, for example, "dd" would represent the number 13 if each "d" stands for 3. Since 215 in base 10 cannot be directly converted to "dd" in a typical base, you'll need to clarify the context or system in which "dd" is used.
A DD Form 214, also known as the Certificate of Release or Discharge from Active Duty, is a document issued to military personnel upon their retirement, discharge, or release from active duty, detailing their service record. In contrast, a DD Form 217 is not officially recognized; the correct form for a similar purpose would be the DD Form 215, which serves as an amendment to the DD 214, providing corrections or additional information. Thus, the primary difference lies in their purpose and official status.
If your retirement award didn't get added to your DD214 upon retirement, you can fill out a DD-149 - just follow the simple instructions on that form. The Army (or branch of service you were in) will send you back a DD-215 when they add the award. The DD149 is pretty self explanatory.
