A pardon, unlike a commutation, makes everything go away, as if it never happened, records are expunged.
True. However, with this woke military leadership they will find a way to destroy his career.
The Sgt will have already been kicked out of the military by the time a pardon comes along. Then there is the notariety.
If a pardon does erase the legal aspects (news to me at this point), it never erases the stress and threats of enduring this legal warfare by the government.
