`titrebThe érosion of the algérien tabous`/titrebThe thesis of adaptation, dominant in academic and strategic circles, explains the transformation of military organizations only from the changes of the international environment since the end of the Cold War, maintaining a deterministic, functionalist and disembodied vision of change. Through the observation of the genesis of the civilmilitary activities in France between 1992 and 2005, we raise an alternative track paying particular attention to the evolution of social interactions between officers. It is primarily the erosion of the taboos systems inherited from the war in Algeria, which contributes to the current transformation of the military actors and organizations.
