I have one more detail that I want to confirm. When moving a stack of units for overrun, the cost for the stack to enter each hex is whatever the cost is for the unit that uses the most movement points.
I disagree. Each unit spends movement points according to what kind of unit it is, and what type of terrain it enters. An INF and a MECH stacked together advancing to perform an overrun, and entering a forest hex on their way would only spend 1 MP from the INF and 2 MP for the MECH. See "11.11.1 How to move land units".

11.11.1 How to move land units
(...)
Each unit has its movement points printed on its counter. Each hex it enters will use up 1 or more of those points depending on:
ï which map it is on;
ï what the terrain is in the hex, and sometimes on the hexside it crossed to enter it, (see the terrain effects chart);
ï what the weather is in the hex (see 8.2.5); and
ï whether the unit is motorised or not (see 11.11.2 ~ option 34).
********************************
So, for simplicity's sake, if the stack does not start in an enemy ZOC can charges forward, seeking to overrun a unit, each hex it enters costs the number of movement points required to move the 'slowest' unit into the hex.
My concern is an armor unit, stacked with a leg infantry trying to move into a forest and then, later in the movement, overrun an enemy unit in a clear hex.
The leg infantry might have 4 movement points which is sufficient for it to move/overrun the enemy unit, since the forest hex only costs leg infantry 1 MP. The armor unit has 6 movement points, and though the move through the forest costs it 2 MP, it still can reach the enemy hex for the overrun.
However, since the two units must move as a stack in order to conduct the overrun, then entering the forest hex costs the leg infantry 2 MPs of its available 4 MPs, so it can not reach the enemy unit for the overrun. The same thing comes up when moving through mountains.
=========
I think that this whole question is based on an error, as there is no "stack movement" that requires an INF to use the MOT movement rates.
I've another bone to pick about overruns.
The rules make a clear distinction between overrunning air & naval units, alone in a hex, versus when enemy land units are present. Now I have no problem with that, it is very clear cut.
But, supply units make me pause and wonder.
1 - Can a supply unit participate as an attacking unit in an overrun? It might be the only way it could get to the overrun hex (otherwise it would be violating the rules concerning entering and exiting enemy ZOCs. I am assuming yes.
22.4.10 says about Supply Units.
********************************
22.4.10 Supply units (MiF option 6)
(...)
They move like a motorised unit but do not change control of hexes they enter. They have no combat value and cannot attack. They are never affected by any combat result.
********************************
So they can't attack, but overrun is not a land attack (see "11.16 Land combat" that says "Overruns are
not land attacks."), so I assume that a supply unit is allowed to be included in a stack of units performing an overrun.
2 - Does the presence of an enemy supply unit count as a land unit for the purposes of overrun? For instance, this might prevent an out of supply unit from overrunning a hex (because an enemy land unit - the supply unit- is present). The MWIF/CWIF code currently says says: yes, the presence of an enemy supply unit prevents movement into a hex (i.e., overrun) by an out-of-supply land unit, even though the odds would be X:0, or infinite.
Here, 22.4.10 Supply units (MiF option 6) says :

Your land units can enter a hex containing only an enemy supply unit without having to overrun it. You can then either destroy the supply unit or replace it with one of your own (chosen randomly).
********************************
So a supply unit don't count as a land unit for the purposes of overrun, and don't prevent an out of supply unit to overrun an hex. It is merely destroyed or captured.
