The Strv-103 is one of a kind, concentrating so many innovative solutions and new ideas into one vehicle, that to this day it has left an unmistakable imprint in tank design, according to most experts. It was a rather original solution to the very unique national defense issues of Sweden during the cold war. Sweden chose to adopt the tank best suited for the landscape it was to fight on, this in turn produced an unconventional solution: a self propelled gun used as a main battle tank, classed and recognized as one despite its obvious lack of turret. It succeeded in this category by concentrating many technological breakthroughs that rendered this paradox possible.
