No argument from me there. I can only speak with direct experience for the Air Force, but I think it's more about keeping people to a "military appearance" (stick-like, apparently) than actually caring about our capability. That, and cardio = health, obviously, and they don't want to spend as much on our health care.
Like I said, you should still be competent with a map. But as of this writing, I've had to rely on one exactly 0 times outside of training. Again, if you're in a specialty that requires it, different story.
I'm not saying lowering the standards in any way is a good thing, just that the implications of this particular thing no longer being a graduation requirement don't worry me that much.
While I much prefer the situation as it is to, say, the Vietnam era, since I can wear my uniform in public without someone chucking a beer bottle at me, I'd still settle for not assuming we're all heroes. It's a dumb assumption. Plenty of people just join up for a pay-check, not because they want to go protect everyone's freedom. And if we're all "heroes", it belittles those among us who actually earn that title.
