According to my knowledge these two, Dalokulu Luthuli and Maj Langeni were within the military force.  And the other three, Gideon Zulu and MZ Khumalo together with Robert Mzimela were politicians.  If you look at the military structure all over it is such that there is a commander who is on the military side, and he reports to the politicians.  Like ministers of certain departments, like Commissioner Fivaz has a superior above him and such as Sydney Mofamade.  That simply means the politician becomes the senior to the one in the military.
