The wall was first dedicated on 14 December 1988 by Director Leonard Perroots at the DIA Headquarters , honoring those DIA personnel " who died in the service of the United States " . It " commemorates the profound individual sacrifices made on behalf of the United States by DIA members and acts as a reminder of the selflessness , dedication , and courage required to confront national challenges ... " The DIA does not provide detailed criteria on who is eligible for inclusion on the memorial . The wall is presumably not exhaustive due to omission of DIA personnel with links to classified missions , such as DIA officer Charles Dennis McKee , who died as a result of the Lockerbie bombing . McKee is notably absent on the DIA wall , whereas his CIA partner Matthew Gannon is honored on the CIA Memorial Wall . The majority of the disclosed DIA fatalities are either a result of terrorist attacks or accidents and acts of violence directed against overt employees . While CIA has a practice of marking the deaths of its private contractors on its memorial wall , the number of DIA contractor losses , if any , is unknown
