The question is why ID did not give their soldier some duct-tape after he learned of the changed situation. So the question is not why the marins do not have lights on their weapons or body pre-fitted. The marine realises he is not in a normal combat scenario so he uses duct tape to adjust to the situation. How does this relate to doom3? Well what happened is pretty realistic. They can only really be used when you are reasonably certain that you are operating at such speed against a less prepared enemy that the giving away your position and presenting a brightly lit target makes up for you being able to see. So lights on weapons or worse the body are a clear sign you are watching a movie. You will see very good in the small cone of the flashlight and be blind outside. Start shining a flashlight around however and your eyes won't adjust. Your eyes can adjust to the dark and make use of what little light there is available. There is also an other reason why not to use a flashlight at night. Now imagine they are soldiers and you are the enemy waiting in ambush. Watch the movie ET and the opening scene where all the cops are walking with their flashlights shining. A swat team could go in with sirens on their head since they are not supposed to stay still and engage a heavily armed enemy. They operate at such speed and with such overwhelming force that the enemy doesn't have time to respond. The only ones who use lights on their guns are special forces like swat teams. Why not just paint your self a big fluorescent target on your chest and be done with it? Putting lights on your body or weapon is a big NO-NO. Sure they make it easier to see but the poor guy operating it will probably be the first to die as he is the easiest to target. With night fighting the flash of your weapon means that after you fire a round you move since the enemy now knows exactly were you are.


So a sniper never stays in one place after a shot (make note snipers who are suprised that after they shoot me I kill them in computer games).

One of the things any real soldier knows is that once you give your position away you MOVE. Lesson 1: DO NOT SIGNAL YOUR PRESENCE TO THE ENEMY.
