Strategy & Tactics magazine #236. They Died With Their Boots On, Volume 1: Quebec '75 is part of the first volume of "They Died With Their Boots On" system, which uses an interactive game turn in which both players command an overall force made up of several sub-commands. During each turn, players alternate picking "command markers," which designate the sub-command within their force they may then use to conduct operations. The player then moves units of that sub-command and, at the completion of its movement, conducts attacks with units of that same sub-command. Play then passes to the other player, who similarly picks a marker and moves and fights. That procedure continues until all command markers have been picked. Additionally, certain events cause players to pick "heroism markers" at random, which may generate anything from mad, impetuous charges to abject surrenders. The rules are divided into the standard rules, which are common to all games in the system, and the scenario rules, which provide deployment and reinforcement instructions, as well as victory conditions, for each specific battle game. In this game, each turn represents one to two months, depending on the time of year, and each hexagon on the map represents 9.3 miles (15 kilometers) across. Units of maneuver for both sides are battalions and regiments, artillery batteries, and a few miscellaneous units of smaller sizes.
