Jep they do have the drop boxes, but as madphisto.net has so nicely said these pic are from the SE version, I actually didn't notice until he said it, I got the pictures from "Looksirdroids" so I naturally thougt they would be of "true" sandies, and I only used this picture to point out my idea of the dirt being camo instead of just dirt.
madphisto.net I dont agree with you that it's useless, and they have covered there hole armor, look at theese pic, it would be **** near impossible to get this dirty unless it's done deliberate, I've been to egypt a few times never have i seen dirt stick to something like this, and once again I know this is a dangerous topic, But tatooine is controlled by the Hutt's, and the empire has no presence there. therefore the sandies in ANH must come straight from Vaders cruiser, (better equiped, but still straight from Vader) and therefor wouldn't have been long time enough in the dessert to become that dirty, and all the troopers look like this even the once in Mos Eisly city.
Doesn't make any sence to me if this isn't some sort of camo.
