The DD Form 254 is used by the military to safeguard classified information released to contracted individuals working with the military branch. In order for contractors or others to have access to classified information, the DD Form 254 must be filled out by the systems engineer on a project.
The security manager evaluates the DD Form 254 and determines the level of classification required. The DD Form 254 can provide access to classified operational system hardware and software, mission scenario materials and weapon system procedures handbooks. The DD Form 254 is reviewed and renewed annually depending on the length of the contract.
