Lang if you’re referring to the two Mortar carriers and the 2pdr carrier, I believe these are in Khaki Green / Light Earth scheme, which Young criticized on 13 Sept 42: “These colours are useless for disruption as they are much too close in tone and merge at a very short distance.” You can see what he means in that photo.
Note also the enlarged frontal pattern on the AT carrier and gun shield compared to the trial pattern, which is otherwise identical. Early disruptive patterns under MC301 were way too small, especially 3-tone patterns, and instructions were issued to make them “bolder”. I believe they were designed originally by Victorian DHS committee and not Dakin himself, although he seems to have approved them. I guess we need to bear in mind that disruptive camo was in its infancy.
