The Laffly S15 was a family of all-terrain military vehicles from French manufacturer Laffly that shared the same six-wheel drive chassis. They were used by French forces during World War II.
A personnel carrier and reconnaissance vehicle based on the same chassis was designated as Laffly S15R. It had a different, lighter rear cab and a different transmission that allowed for higher road speed.
Laffly was a French manufacturer of trucks and utility vehicles. Founded in 1849, the Laffly company began manufacturing utility vehicles in Billancourt in 1912. From the mid-1930s and until World War II, the company also manufactured a range of offroad military vehicles such as the Laffly S15 and Laffly V15.
Probably best remembered today for its firetrucks, the Laffly company closed shop during the early 1950s.
