On the game menu bar click on Help to activate the pulldown menu then click on Parameter Data (F2)
This will open a window showing many of the values of the pdt file Scroll down the resulting window until you see something like this
Breastworks Values
Movement: 2 Combat: -50% Building: 20%
This gives the additional movement cost for crossing breastworks, the combat modifier and the chance of building them. These values vary from game to game and sometimes from pdt to pdt within a game. To the best of my knowledge it is not dependent upon terrain and I'm not sure if the unit size has any effect or not, if so that is hard coded and not adjustable in the pdt.
Some of the infromation in the pdt file does not show up in this window. The ACWGC Engineering pages have information on everything the PDT files control and where that is located in the file. You can find it at
