Practice Relating to Rule 8. Definition of Military Objectives
Section A. General
Colombia’s Military Manual (1999) states:
Objects that are normally of a civilian nature can, according to the military situation, become military objectives (for example, a house, a bridge tactically used by defenders, and therefore a target for the attackers). … Military objectives are those “objects which by their nature, location, purpose or use make an effective contribution to military action and whose total or partial destruction, capture or neutralization, in the circumstances ruling at the time, offer a definite military advantage”.

The Report on the Practice of Colombia notes that the government and the Defensoría del Pueblo (Ombudsman’s Office) have adopted the definition of military objectives laid down in Article 52 of the 1977 Additional Protocol I in order to draw a distinction between military objectives and civilian objects.
