When Technology Meets Tradition Early 20th Century Rules
“When Technology Meets Tradition” is a set of rules for wargaming early modern warfare conflicts, roughly from 1895-1915. The emphasis of the author is on early World War I (1914-1915) but other period wars are also of interest, such as the Russo-Japanese War or the Boer wars. The rules are fast-play and focus on the problems faced by military tacticians during early modern warfare: when outdated linear tactics and love of the offensive ran head-on into lethal, accurate, and rapid firing weaponry.
