In the new EO here:

The most significant part(s) (IMHO) are the 2 clauses relating to changing sentencing or verdict. This enables the JAG to get the guilty finding and get the perp to rat out the next higher up and up and up.
This is freakin' brilliant!!!
(3) authorizes the convening authority to modify the findings and sentence of a court-martial, dismiss any charge or specification by setting aside a finding of guilty thereto, or change a finding of guilty to a charge or specification to a finding of guilty to an offense that is a lesser included offense of the offense stated in the charge or specification;
and
(5) authorizes the convening authority to approve, disapprove, commute, or suspend a sentence in whole or in part.
