A novel, unique feature was a three-man turret. This meant that commander was not distracted with performing either the loader's or gunner's tasks and could fully concentrate on maintaining situational awareness. This gave a huge potential combat advantage, but went largely unnoticed at the time. Except for the Lago prototype, a predecessor to the Stridsvagn m/42, produced by Landsverk in 1934 no other manufacturer constructed a tank with a three-man turret until the German Panzer III. The practical importance of this feature is signified by the fact that later into the Second World War, most of both sides tank designs either quickly switched to the three-man turret, or were abandoned as obsolete.
