Overrun: Says it's one movement point per squad that you want to overrun. My question is:

-Is this the total cost to enter the hex? Or is it in addition to the cost to enter the hex normally?

-Do you have to spend 1 or more movement points to then leave the hex afterwards?

Example: A tank starts its action adjacent to 2 enemy squads. Both are in clear terrain. The tank owner wishes to pin both enemy squads. Would he have to pay 1 movement to enter the hex, 2 movement to pin the squads once in the hex, then another 1 movement to exit the hex for a total of 4 movement points? Or could he enter and pin the squads for only 2? Does he have to have enough remaining movement points to exit the hex containing the enemy squads?

Removing razor wire. Says a heavy vehicle can spend 2 movement points to remove razor wire. Is this 2 movement points that has to be spent while you're already in the hex?

Ad Overrun:

No, you need additional 1 MP for each enemy squad on that hex + normal number of MPs needed to enter that hex. Tank must have enough MPs to leave that hex, because it can not remain on a hex with enemy units.

But the effect of overrun does not happen automatically - if those squads are in trenches or pillboxes, it won't work. If they are in Op-fire and hit your tank(at close range!) they are not pinned and your tank returns to the last hex and is fatigued (and damaged).

Ad Razor wire:

After you have entered (with your tank) a hex with a razor wire, you may spend additional 2 MPs and remove it.
