Yes, but you have to see that there is little place for purely defensive weapons in a modern battle field. In order to defend, you must conduct counter-attacks, and in order to do that you need armour(for now, at least). There is no point in having tanks that are only capable of defense. By the way, the Sweeds called the S-103 an MBT, which to me is a joke. It is a Tank-Destoryer, maybe a Heavy Tank-Destroyer. Also note Sweeden dose deploy the Ikv-91 Tank Destroyer,a 16000 Kg vehiecle witha 90mm main gun.
