for non military yes, but not for military.
yes, you still need warrants, difference is it's done by a military judge. I had to do them.
But not for investigative procedures. So during the investigation, any publicly (open source) evidence you don't need a warrant. But surveillance and accounts, you need a warrant to investigate.
remember that these people will be held to National Security crimes as well as criminal crimes. Disclosing classified material falls under Counter-intelligence purview. Much higher prison sentences and possibility of death penalty, though only one person in recent history has been given death. His was commuted to life.
