Good summary there Plastic.
Pertinent points to raise would probably be the operational aspects too:
Goggles are by no means a replacement for day vision because they provide a monochrome image (hazy shades of green! isn't that a song title?), markedly reduce your depth perception, and I think most importantly remove a good chunk of your peripheral vision.
With the most common types of goggles around in the military, you only get about 40 degrees of vision (the area in front of your face) rather than the nearly 180 that normal day vision gives you. It means that you have to use other strategies to give yourself a lookout that covers what needs to be looked at.
As one of my goggle instructors succinctly put it, "You have to move your head around like one of those noddy dogs that you find in the backs of cars."
