Further, the commandos must make efforts from the beginning to seek out among the prisoners elements which appear reliable, regardless if there are communists concerned or not, in order to use them for intelligence purposes inside of the camp and, if advisable, later in the occupied territories also.
By use of such informers and by use of all other existing possibilities, the discovery of all elements to be eliminated among the prisoners, must succeed step by step at once. The commandos must learn for themselves, in every case by means of short questioning of the informers and eventual questioning of other prisoners.
The information of one informer is not sufficient to designate a camp inmate to be a suspect, without further proof; it must be confirmed in some way if possible.
Above all, the following must be discovered:
All important functionaries of state and party, especially
Professional revolutionaries.
Functionaries of the Komintern.
All policy-forming party functionaries of the KPdSU and its fellow organizations in the central committees, in the regional and district committees.
All Peoples-Commissars and their deputies.
All former Political commissars in the Red Army.
