The word "technical" does not appear anywhere in the UCMJ. Technical orders are Air Force specific. There is no distinction between general orders and other kinds of orders in the military at large.
The proper term "Technical Order" is indeed salient to the Air Force, but the notional concept of a "technical order" is precisely what the parent describes and exists in all branches of service, deriving its authority from a long traceability chain that terminates as a general order issued by the Secretary of the respective branch of service, e.g. in the Navy, its functional equivalent is a "Technical Manual".
I beg to differ on distinction. Whereas both uniformed and civilian personnel are required to comply with executing technical orders per the same chain of authority, the latter is almost completely shielded from the punitive hammer of the UCMJ.
