What form should be used for documentation outside of 15 years?

The appropriate form to use for documentation outside of 15 years is the DD 193. This form is specifically designated for requesting copies of military records that date back beyond the standard retention period, which is particularly relevant for veterans who may need verification of their service after a significant amount of time has passed.

In the realm of veteran documentation, using the DD 193 acknowledges the unique situation where veterans need access to records for benefits or other purposes that extend beyond the typical 15-year limitation, which is often a hurdle for many service members and veterans accessing their historical records.

Other forms mentioned serve specific functions within military documentation but are not intended for this particular purpose. The DD 214 is primarily used to summarize a service member's military experience upon discharge. The SF 180 is a general request for military records but does not specifically address requests extending past the 15-year mark. The VA 29-336 form is related to service-connected benefits and is not a document for requesting historical military records. Thus, the DD 193 stands out as the best choice for acquiring documentation outside the typical timeframe.
