The "aid and comfort" prong of treason has been interpreted
by SCOTUS as requiring proof of four elements:
1. an intent to betray the United States (which can be inferred from);
2. an overt act;
3. witnessed by two people; and
4. that provides aid and comfort to an enemy of the United States.
‘bout sums it up...
You can go find similar language in the UCMJ...
But, I am not sure the UCMJ applies to service members anymore, since they re allowed to lawyer up with civilian lawyers outside of the JAG or other military legal system...
Just look at the Hassan case (Ft. Hood)...There are a couple more capitol cases that I recall vaguely...Just don’t remember the names involved right off the top of muh head...
