I am trying to sign a form I have filled out digitally, all fields are open including signature block but the Sign Document under tools is greyed out. the form's title includes "(SECURED)" after .pdf. is there a security setting I need to remove? Here is a link to form i am filling out www.dtic.mil/whs/directives/infomgt/forms/eforms/dd2853.pdf

The fields in the signature area are not digital signature fields, but rather are normal text fields, so it's intended for you to type your name. If the form did have digital signature fields you would be able to sign them. The type of security that they've applied does not permit you to create new digital signature fields, which is why Sign Document is greyed-out.
