Units moving out of 'Difficult' terrain.

[T13A]

Hi

Just a generic query, say in the rules you play that units move at half speed in woods and you have a unit in 'march column' (for sake of argument) where the front of the column has moved out of the woods but part of it is still in the woods, on its next turn does it get a full move or does it still move at half speed (just using woods as an example of 'difficult terrain)? 

Just wondering if there is a general consensus on this or people play it in different ways.

If any of the unit is still on the woods, then you still get the half speed move. Surely? At least until you clear the woods.

We play that if any part of the unit is still in the terrain, then the whole unit is slowed by the terrain. 

But once they clear the terrain they can move at full speed, for the rest of that turn. 

Eg, a unit has a 6" move speed, and the wood costs double the move distance. 

They start in the middle of the wood, can move 3". Say that gets the unit half out of the wood, so that only 1" of the base is still in the wood, then next turn they move 1" out of the wood (costing 2" of movement) then can move a further 4" in the rest of the turn in the open.

I'd go with worst modifier any part of the unit is in, like Raider. I always assume unit footprint on the table is the area the unit takes up on the field.

Consider the unit approaching where the woods are only part of the frontage. The following example is for a horse and musket line, 4 bases wide:

There are woods that blocks the rightmost base as the unit advances. This would block the base - they can't move at full speed because of woods. The rest of the unit would have to slow to keep the line intact.

In the rules we usually use (BBB), if any part of the unit is in Difficult Terrain at the start of the turn, the unit incurs both an activation penalty and (if it manages to activate) a movement penalty.

I think the issue is not a problem when you talk about a single unit, as that is either in the terrain (restricted) or out of the terrain (not restricted).
The challenge occurs when you have a formation (order group) where some of the units are in the terrain and some of the units are out of the terrain.
As a general rule - I'd played it that if you want to order the entire formation as one entity, then the whole formation moves at the rate of the slowest. That seems logical to me, as the commanding officer would be trying to keep the formation in order.
If he/you wanted the units outside the terrain to move ahead, you'd give them a separate order to do so, dropping those in the wood from the formation for command purposes. Or you could drop the units outside the terrain and attempt to order the units in the terrain to move around them and out of the terrain.
