There are three core movement modes listed in the movement section:
Ground, Standstill and Jumping
If a unit chooses to move at least 1” and is not jumping it is using Ground movement and gets its TMM value.
If a unit chooses to not move the minimum of 1” it is classified as being at a Standstill.
Note: Standstill doesn’t clarify that ground movement is required. Merely that the unit move less than 1”. It then gets a 0 TMM and a -1 modifier to hit. The unit is “making a choice to not move at least 1”.
If a unit can jump and declares/chooses that it is Jumping, and moves less than 1” (IE it is going up and then coming back down in the same location) is it counted as being at a Standstill for the purposes of calculating the TMM because it moved less than 1”?
And then the “jumping declaration” is ignored because the standstill rules would over-ride as the unit “didn’t move the at least 1”?
If a unit uses all of their movement allowance, and ends up within 1” of their starting location (or in their starting hex) does that count as not having moved at least an inch and being at a Standstill?
Or, for the unit that declared the jump, because it declared that it is using jumping override the lack of horizontal movement distance and because of the jump no longer qualifies for Standstill and gets the TMM+1 value? (Assuming that this isn’t a JMPW or JMPS unit.)
