It did, but as I noted in my subsequent post, it was a one-man turret, diminishing it's effect. Also, the tanks were not deployed and used en masse but rather penny-packeted into the fray as infantry support. So yes, tactics and design both played a role.
Indeed, you'll see contemporary British ref to "cruiser" and "infantry" tanks - e.g. the Crusader III and Churchill, resp. The two had expressly different purposes.
Von Krimm, who berates my lack of a search, mistakenly refs. Crusader IV in his sig but I believe he means Cromwell, since Crusader IV doesn't exist. Regardless, it was of the former type and was an evolution of the Crusader series.
