NLW are intended to have reversible effects on personnel or materiel.”QUESTION: What is considered a NLW?ANSWER: The definition of NLW includes “weapons, devices and munitions.” This definition is very broad and includes devices and munitions that are not normally considered “weapons,” such as acoustic hailing devices.Why are NLW important?ANSWER: NLW provide another “option” for the force. In past operations, the effective employment of NLW resolved escalation of force situations. Specifically, the NLW created the right “direct effect” on the personnel/materiel targeted. The use of NLW has also generated positive “psychological effects” on others in the area and helped to contribute to mission accomplishment. The perceptions associated with the use of NLW have been a positive and powerful influence in local communities in “winning the hearts and minds” of the local populace. The employment of NLW has helped reduce the loss of life and collateral damage.
