"Field General Court Martials can only be convened if it is not practical to try a case in another court (military or otherwise)"

Ah Raggy definitely not a legal expert then, so in future please do not lecture us on legal matters.

Field Courts-Martial are one thing.

General Courts-Martial are another thing entirely.

Now toddle off do some googling and then come back and tell us all the difference.

If you need a compass I'll lend you one.
