A little thing I learned about night vision from an Air Force survival instructor. Any light other than red, no matter how bright will destroy your night vision. With that, it doesn't matter whether the flash goes up or out, your night vision is gone when you pull the trigger. This is for black out conditions. Ambient light, such as a street light, will allow you to see the figure you shot at but no details like whether he dropped the weapon or not.
SOMEWHERE, SOMEONE IS TRAINING FOR AN ENCOUNTER WITH YOU. STILL WANT TO QUIT?
