This year marks the 20th anniversary of the libertarian antimilitarist group Ni Casco Ni Uniforme (Neither Helmet nor Uniform - NCNU). NCNU emerged as the NCNU Conscientious Objection Group, originating in Santiago de Chile in the context of democratic transition. Compulsory military service existed then and now in Chile. There was (and is still not) any law protecting conscientious objection to counterbalance this. In this context, conscientious objectors, antimilitarists, anarchists, pacifists, feminists, religious people, students and workers come together in a series of coordinating initiatives from which emerged a political body willing to act together in Ni Casco Ni Uniforme, in that year 1997.
