Form says, "You cannot save typed data into this form"

[Guest]

I have downloaded a PDF from

http://www.people.mil/Portals/56/Documents/rtm/mrep/FY16MREP/DD%20Form%203006%20-%202016%20MREP%20Ap...

When I open it, the message states, "You cannot save typed data into this form". It also does not allow me to add digital signatures to the form as well. It does not have the option of saving as a Reader Extended PDF.  I also saw in the documents restrictions summary that signing is not allowed. Does anyone have ideas how to save changes and take off signing restrictions?

The creator of the form doesn't enable the save rights. Fill the form and print it.
