Well if you take a look through all the photos, some of the figs have some small changes, from the final product:
1) Scrap –Iron from the arctic set had a transparent visor, but the final production fig did not.

http://photos.yojoe.com/showphoto.php?photo=3857&cat=609&perpage=305) Croc Master had the most changed. The pic shows a black whip and hose, the forearms are switched and the “belt buckle” is painted yellow instead of green:

Final product is more blue, neck paint gold or black, and cape included

Like danielb said looks like the bazooka trooper was supposed to have two helmets.
My bazooka trooper is also missing the holster. I guess for whatever reason, Hasbro decided not to include it, as with the many changes they made above, as opposed to a factory error.
It's a bit odd since this is a "accessory change" as opposed to a paint change.
Would have been nice to have though.
