On pg 52 it states"
"A unit’s current heat level will be added to its weapon attack
Target Numbers, and twice its current heat level (in inches) will be
subtracted from the unit’s ground movement rating. (Jumping Move
is not affected by the heat scale.) Subtract 1 from the unit's Target
Movement Modifier (TMM) at Heat Level 2 or higher."
Does the -1TMM affect both ground and jumping movement, or does it only apply to ground movement?
