FiveCore Brigade Commander: Brigade Level Warfare in the 20th Century. By Ivan Sorensen. While the rules are not written for any particular scale of miniatures, they will work very well with 3mm, 6mm and 10mm figures, where each stand can look like a unit in its own right. Playing in 15mm is certainly possible, but tank models will take up a disproportionate amount of table-space compared to infantry stands. GROUND AND TIME SCALE: The game does not adhere to a strict time scale. A turn is the time it takes for a meaningful action to take place on the gaming table and for units to potentially incapacitate an enemy company sized formation. Depending on the actions taking place, this may be from a few minutes to half an hour or longer. If you are tracking time for the purposes of a scenario, assume an average of 10 minutes per turn or roll 3D6 each turn, to determine how many minutes it took. Think of your game as a movie. As the battle rages, the camera zooms in on a particular unit and focuses on it, while the rest of the world ceases to exist for a moment. Ground scale is roughly 1” = 100 yards. Engagement distances have been kept very conservative, to account for the fact that our flat, featureless tables would be covered in hedge rows, hills, crevices and depressions.
