I ran this last weekend, and while my players had fun, I believe it has more to do with the people at my table plus my own preparations than the scenario itself. There's promise and it is definitely something different, but a couple of missing hooks to drive the players to perform correctly are missing.
I played the drill sergeant with a mix of Major Payne and Patches O'Houlihan in mentality for the insults and harsh treatment given; the players enjoyed it and the fact that several of them were either military or knowledgeable of the military helped get them enjoy playing along, even as the scenario turned south.
The biggest problem is that there's a few light clues that hint that something may be shifty (and by whom), but there's little reason to break protocol and look for the clues. This is especially important when it comes to the end of the scenario, where the lack of clues can prevent players from truly figuring out what is going on and possibly even earn the second prestige point.
They aren't listed, but giving life to the other soldiers in the unit does much to make the experience feel fuller and, in hindsight, could have been used to push the players to find more clues.
I'll give the author credit for doing a different route and hopefully with some polish, something similar can be excellent!
