I find these rules very realistic. At least to me. Having started with the original Warhammer History rules which sad was cancelled. Only to be brought back by Plastic soldier company. Battle ground Normandy and Kursk. The game limits your actions, makes you think about what is your next move. Only to find out there was really a tiger been the bushes.
No better to explain the rules than by the author, Mr Warwick Kinarde. Below is a link from Model Dads Blog. If your have time to watch the video, let me know what you think about the rules:
