I hunt wearing a ghillie suit that I made myself. In my opinion, camo use in military and camo use in hunting are two totally different perspectives.
When "hunting" humans or trying to not be detected by humans during military operations, camo is an advantage, as the human animal is preprogrammed to look for a human form or outline.
Animals have an alternate view, as they are always looking for something not quite right. The best camo in hunting either makes you blend in, so you are virtually invisible, or breaks up your outline.
What many forget to "hide" is their eyes. Eyes will always give you away. I use black all around my eyes and lids, and make sure that some of the jute from my boonie cover hangs down to break up my eyes also. And yes, keeping still and silent is very important.
