These were made available at Ft Jackson's Drill Sgt School and I used them while up there.  They are far better than the standard US Army issue gloves, although not nearly as warm (i.e. liner + shell standard Army issue).  They are light, windproof, and waterproof.  The outer shell will soak with water, but my hands didn't get wet.  As long as you keep your jacket over the top of the glove and water doesn't go down the arm, you'll be fine.  Be advised if you get your hands into snow, it'll FEEL like your hands are wet, but they're not actually wet.

They're fine for keeping out the biting wind and I use them for motorcycle riding, and have gone through South Carolina monsoons (LOL) and my hands are still dry.  The rest of my body dripping wet, but once I arrive at the CQ and take my gloves off, my hands are dry.  Awesome.
