I looked up WS030 and the patterns they are wearing (pea dot and Italian camo) have in fact been used on many subsequent figure sets. Perhaps they haven't been done as well, or are a darker or lighter shade, I don't know because I don't own any of the early WS sets personally to compare directly with the many later figures that I do own. I'll tell you, I was impressed when I saw some of the figures from WS027 integrated into Carlos' diorama here a few days ago - their camo stands up quite well alongside more recent releases and that's a set I might have bought if I could have back in the day.
