because f*** turrets, were gonna make a tank with a fixed gun that cant be killed from the front and is fast as hell and really accurate and cheap to mass produce and looks totally badass at the same time. gotta love the swedes.
Well it could turn faster than other tanks could turn their turrets and was fast and low silhouette and powerful gun. They used the same tactics as Stug tanks and no they are no city tanks xD Suggest you to read those tactics, they are great at attack and defence if used correct which the Stugs showed very well in WW2. Tanks should never be used in cities, they are weak there, simple tank tactics is to avoid using tanks there.
