Why some Second World War commando operations remain obscure

Are Second World War commando operations still classified?

Quite possibly; historians may know that an operation happened without knowing its real task, and some operations may have covered for others.

Numerous commando operations may remain confidential or only partially documented. Norwegian examples are known to have occurred while their precise purpose stays unclear. Some named operations may also have served as cover for different activity, leaving historians with deliberate gaps in the record. An operation name can survive while the evidence needed to interpret it remains fragmentary or deliberately misleading.
