Winter terrain in Steel Panthers portrays more of a "light snow" ground condition and units generally just spend one extra movement point (depends upon weather setting, see farther below) while entering most hexes. Not much for motorcycle troops as they are some of those units with very high movement allowance (55). Also breakdown chance appears not to be increased for "Mixed" winter terrain.[&:]
If you want more of a severe deep snow winter condition, then you can use a little tool called "Mud Machine" which is part of Ectizens scenario designer quicky tool (SDQ). You load a map, a scenario or a save game into "Mud Machine" and apply a "mud" terrain layer to any "Mixed" terrain. In fact that converts all "Mixed" terrain to "Mud" without changing any of the winter graphics and internally the map/scen/save game is preserved as a "winter" game![8D]
Now on any such treated map, motorcycle troops (which are of the "Wheeled movement" class) will have a very difficult time when moving through those "deep snow" (erm..mud) hexes, as every move burns up 10 MP now! Breakdown chance is increased as well. Benefits for ski infantry units fortunately still apply (-1 MP/move). Above said counts for good (clear/cloudy) weather. If weather is really bad (snow/blizzard), upto 2 additional MP are burned per hex moving.[:D]
On any map "tweaked" as mentioned above, your troops now need to rely more on a road net if present.
Ectizens scenario designer quicky tool (SDQ) s/b available at the SPWAW Depot. It´s easy to use, even if you´re NOT editing or designing scenarios usually.
