Modeling the LRDG and SAS in 15mm?

[NickNascati]

All,
     My preferred scale these days is 15mm, and my preferred source for WWII figures is Peter Pig.  Looking at the photos of different British packs, it appears that the Home Guard sets may in fact be wearing watch caps.
      To create fairly accurate figures primarily for North Africa, what figures from PP would you all suggest?
