Military staff officers are constantly attacking traditional fieldcraft, partly because it's the part of the course(s) that fails so many students, and partly because they claim that the changing role of the sniper makes traditional skills obsolete. Thank goodness the administrators have not yet gotten their way. Because the fieldcraft necessary to the craft is the same; the application of it is what differs.
I remember this a LOT. I was an SDM instructor at Ft Lewis, and the only thing that kept it going was that Col. Brown gave a shit about the ability to hit what you aim at --and fieldcraft. In addition to SDM, we ran everyone through pre-sniper and pre-ranger courses --you couldn't go to the school if you couldn't pass those. I think success went up to above 70%?
Problem is, most of these kids have no idea how to act like an Indian. They crash around the fucking woods like elephants; you can hear 'em coming a mile away. They cook their MRE's, ALWAYS, and eat the shit that stinks. They have little situational awareness nor the ability to range and track movement in a methodical way. Sometimes the cold bean burrito can save your ass.
I grew up hunting, and one of the things my dad made me do was to lie next to a log all day without moving (seriously). Couldn't go on the hunt if I couldn't stay still. Then it was how to walk through the woods, where to step. Then camo. Shooting, it seemed, was the last thing I needed to learn. And that was right. As it is, I've had at least one deer walk right up to me (in training no less, until my platoon came crashing along) almost petted him, and had a turkey so close I could almost snatch his ass up by hand.
Now it doesn't matter if you hunt animals or people, same thing. If anything, animals are much harder, they won't let you get close. It isn't hard to get close to people when you know they are coming down that draw downwind right towards you; you've smelled their food and heard 'em two miles out.
But in the desert, I guess range really is more valuable than fieldcraft. I watched something about snipers on History Channel a long time back, another on SF and Rangers. Remember them talking about how time and again we lost the skills --after WW1, WW2, etc., until (forget his name, a Marine) decided we needed a school to pass it along.
SO, if I had to guess today, I'd say not much as changed regarding the fieldcraft in the SCHOOLS, but in the army as a whole, yeah, it suffers.
