I assume only officers or JAG's would be handling the high level / top secret Indictments. If lower level soldiers (working in these intelligence divisions) don't understand that the consequences of loose lips = Court Martial & Treason, it serves them right for becoming publicly prosecuted examples for any others who might be thinking of leaking this info.

We know for a fact that the Trump Administration has purposely leaked carefully crafted information to specific teams to track down who the leakers are. Anyone working under the 470, must understand these tactics are also extensively applied by the military.
