Hi Marc -
I put in the possibility of removal of the chips in case the player was faced with a huge attacking force and wanted to withdraw everything but did not want the enemy to capture and use all of his entrenchment. (kind of a scorched earth thing)
I put some entrenchment in the Causasus because on my map Stalingrad is located there. I didn’t put any in Hitler’s Atlantic wall because my map starts in 1942 and the player can always add some later. Plus the German player gets an automatic 3 entrenchment anyway when the Allies try to land from the sea.  Â
Okay, thanks for the clarifications. About the scorched earth thing, the ideal technique (and I’m just kidding here) would be to wait until the attacking enemy infantry falls into the abandoned entrenchments, then to fill in the trenches by blasting their walls with pre-set charges of TNT. Sort of killing two birds with one stone. :-D In fairness, U.S. troops sometimes used a variation of this technique in the Pacific. When confronted with a particularly tough dug-in Japanese position that would cost a lot of American casulties to clear by conventional assault methods, the troops would simply use a bulldozer to fill it in or collapse it.
