Half of the day is dark. Imagine WROL, Street lights don't work. Only candles.
Now how many of you have night vision and what kind of night vision? I believe having night vision is a critical prep in surviving during the night. You can't see him you can't shoot him.
I've invested into 2 night vision set ups. ones for just spying at night, general Recon and the others a head mount device. I do have a surefire flashlight with a IR filter on it.
One is a Bushnell stealthview and the others an ATN viper head mount.
