The Sexton was a Canadian self-propelled artillery vehicle designed in 1942 and manufactured by the Montreal Locomotive Works. It was put into service with British, Canadian and other Commonwealth forces in 1943 and replaced the M7 Priests and the Bishops in British service. It was built on American tank hulls, fitted with a modified superstructure and added a QF 25 PDR as its main gun.
It differs from its counterparts, the Wespe and the M7 Priest, because it is a single-seat vehicle. It trades the burden of requiring two players to operate for weaker armor and damage. For example, when tested against a Panzer IV, the Sexton was destroyed by a single main cannon shot to its rear, whilst the Wespe needed two. Another test was conducted for its damage, where it took two shots to destroy a Lynx scout car, whilst the Wespe only took one. Nonetheless, the Sexton's rate of fire, range and blast radius is similar. It is not a frontline vehicle, and should be used to support advances, rather than taking on enemy armor head-on.
