It's good to see you weigh in here. I would also like to hear your opinions on the various combloc patterns. I always found the camo effect of those Gorka smocks fascinating. Using the contrast between the camo areas and the solids in big block shapes was an interesting concept. Kinda like having a macro pattern mixed in with a micro to break up the overall shape/size.
Here's the thing with me and this debate over macro vs micro pattern. In a meeting engagement, which we can use as a good example of what camo is trying to do, i.e., delay the onset of recognition, I have either heard something crunch or snap, seen movement or an outline of something moving behind the bush, or even smelled something funny. Sometimes it just got real quiet and the hair on the back of my neck stood up. In other words, many other target indicators were present before any disruptive camo pattern came into play. The guy could have had a solid green or brown on and it wouldn't have made any difference. Now granted, most of my experience was in jungles, and dense woodland areas. And most of the time we moved at night. So yeah terrain and situation. Texas is probably gonna look a lot different!
But here's the kicker. I've had my buddies patrol towards me slowly, taking frequent security halts, just like old sarge taught us. What you would see is some dude getting up slowly and see a dark outline moving. By the time you could discern a camo pattern, you could also see a face, a rifle, and bunch more shit you should be worried about. Again this is the US southeast, in rolling woodland terrain.
So maybe the upshot of all this is to test it yourself, in whatever terrain you might find yourself in. You don't have to use a "universal" pattern that works everywhere; you can tailor it to your area. Now there's a concept. I like the big, disruptive shapes on DPM and woodland camo. We all mother-fucked it cuz the snipers looked through their 40x spotting scopes and derided the "dog bones" and "shoot me" double U's. Well, I think a typical situation, at night, isn't going to be a guy crawling up to a final firing point, with the oppo scoping him out with high-powered optics. That's a corner of the envelope that was exaggerated way out of proportion to a typical meeting engagement.
But more importantly, don't look at camo recognition in a vacuum; have live opponents patrol in on you, under different conditions, and see what happens for yourself. A nice warm night, when you're well rested and fed, is a far cry from cold, drizzling rain, where you're half-sick, exhausted, and trying to stay awake. Day optics vs NV. Woodland terrain vs wide open.
I've said it before, and I'll say it again. I think a lot of this camo mania we've gone through in the last few years has more to do with branch distinctiveness, rather than real camo value. I think the old school woodland camo is making a comeback in some circles because it works a hell of a lot better than a lot of folks give it credit for, and they are tired of all these rotating camo patterns of the month being touted as superior to it, when in reality it matters very little. Just about anything you wear for two weeks straight in the bush is gonna blend in, I almost guarantee it.
Regardless of what you wear, it's still good fieldcraft. Terrain masking, proper movement technique, good personal camo (overall, not just clothing), light and noise discipline, and so forth. I2 and Thermal are still just line of sight. If we practiced this as much as we worry about camo, we'd all be ninjas.
