A pathfinder squad, I guess, but using standard fire warriors. Thought about skis but decided on snow shoes instead. The portable mini-drone is inspired by the current US trend for man-portable mini UAVs carried by squads.
Badly would be the norm! My figure painting has never been that good, even in larger scales and after 30-odd years of practice.
Being wintry, colour choices are limited. I'm thinking mid-grey clothing with white armour, possibly with a grey pattern if I have the patience and finesse. I've tried Woodland Scenics snow on some test pieces for the bases. Much better (and better value) than the over-white GW stuff, and sets a treat with WS' own scenic cement. I got a cheap kitchen shaker from my supermarket which works a treat for sprinkling fine scenic powders.
