NOTE: MUST use Microsoft Word
Enter the game, start playing as German in campaign, when you are in the debriefing room look at the requisition points for the current operation (mission is surrounded by a yellow box) and memorize the amount. Press cancel and return to the main menu. Select other than campaign press [Alt+Tab] to return to the desktop, start MS Word, open the saved game with word text editor (backup the file first). Search for the string "//Req points for operation" -without the quotes - it has many strings keep searching the string where you will find the number you memorized and change it to 1500 or more (1500 is enough). DO NOT DELETE THE SPACE BETWEEN THE NUMBER AND THE //.. if you made it undo (it's a formatted area).
NOTE: You can also change ALL of your req. points for the ENTIRE campaign. Change the above specified lines depending on how the names of the men in the unit sound (if you're playing as German change only the German names, etc)
