Try 'em in Alaska. They do cold and ugly -- hot LA (even in winter) isn't their locale without some additional training.

Not that they're super soldiers or super scouts, long as I was around only met three of those (and I sure wasn't one). Good, yes -- but not super, job's too hard for more than one out of a 100K or so (if that many) to be super. No unit is gong to be super and even the good ones go through bad patches.
