Troll "Uhyret"

A design submited to the Army by Troll, inspired by the grand siege mortars of the Great War. Just as Soviet and German engineers, the deigners at Troll Bilindustri had the idea to put a large caliber weapon on a large tracked platform creating a self-proppeled siege mortar capable of cracking fortifications and destroying natural obstacles.

Employing a British 209mm cannon, cut down and modified to a short range high power mortar. Due to the large cost and complexity of the hull and engine only 4 ever made, even so thes served with destinction on the Swedish front, being used to destroy the fortifications along the border as after German forces had been expelled from Østlandet by a joint Franco-Norwego offensive.
