Fields - Brush - Tall Grass TEC

[Dan Storm]

Good afternoon All.

Fields - Brush - Tall Grass.
1.5 MP Foot.
4 MP Motorized.
3 MP Mechanized.
Limiting Terrain = Yes.
See Notes:
Fields - Brush - Tall Grass In Winter (Dec - Feb turns in any but tropical climate) treat this as clear terrain (not limiting terrain for anything)


So if we are playing a January Scenario in Germany - do MP Costs change to those of a clear hex or do the MP costs for a field never change? 

Thank You!
