I'll have to revise my opinion of the Saint-Chamond - I used to think it was a slow vehicle but the manual says it was capable of 12km/hr (7.4 mph) although
it probably wasn't recommended to run the engine that hard for extended periods.
Part deals with the Main gun (two types) machine guns and armour, I've not looked that closely just flipped through but their certainly worth downloading for the info contained... for those with little French language like me, the text can be copied into a translator and works pretty good.
