As we get closer to the Operation: Imperative Action 2015-03-14, which is a night operation, I am becoming more and more obsessed with understanding how the human eyes adjust to the night. I have found some articles that provides good insight:

Use of red light can help preserve night vision.

Excerpt: We have just gotten done with the first night operation at Evike Airsoft Camp 2014. It has been a lot of fun with a lot of friendly people. I have gotten more tactics to share. 1.
