Let There be Light

摘要

The challenge is in cleverly utilising each at will to achieve the tactical advantage. Being able to change a situation from being shrouded in complete darkness to illumination by a directed brilliant beam of light, particularly one that is unexpected by those so suddenly illuminated, can provide a critical edge in an encounter: Just think of the dazzling effect of full beam headlamps on a dark road at night. Moreover, in a situation where hostages or non-combatants may be present positively identifying who or what one is facing is imperative. 12 weapon sights and NVGs have limitations in providing clear identification, depending on the quality of the imagery that they generate; witness the fuzzy, eerie green light that some night vision devices can produce; and may not even be able to provide an image if ambient light is not available which can be the case in rooms, hallways, basements and tunnels. This is because conventional night vision technology relies on at least some ambient light being present so that, put simply, light particles can be amplified to create a night vision picture. In these cases the use of visible 'white' light or, alternately providing infrared light to supplement the ambient light for 12 devices is necessary and may even be preferred by operators. A tactical team instructor with former infantry background stated to MT: "The tactical light remains the single most effective system for addressing search, identification, control and engagement in indoor limited visibility situations.".
