The law of armed conflict is well developed and covers a wide variety of aspects of warfare. This law offers protection to victims of war and limiting permissible means and methods of warfare. Common sense would suggest that such rules and the limits, which they impose on the way war is waged, should be equally applicable in the international and non-international armed conflicts. The author is trying to study the use of the law of armed conflict, which occurred in Libya in 2011. Some conclusions in the end of the study on how the law of armed conflict will be use well in the future battle field can be summarized. This study provides evidence that many rules of the law of the armed conflict apply in the non-international armed conflicts, and also shows the extent to which state's practice has gone beyond the existing treaty and has expanded the rules applicable to the non-international armed conflicts.
