Do they trust their soldiers/Marines with these encryption keys? Don’t know that.
It's interesting to see how the Army and the MPAA respond differently to the same problem - it only takes one person to crack the code (or leak the secret keys) to render the whole scheme useless. The MPAA builds ridiculously complex encryption schemes in the hopes of slowing people down, and sues the downloaders it can find. The Army doesn't bother with encryption because it's too much of a burden, and kills the downloaders it can find.
