A Sword of War

The world finally sees the terrifying prowess of the Berserker army

They fight even if they lose their limbs and some even fight even after losing their heads. One soldier even uses his own head and throw it to other before kicking the enemy, took back his head and forcibly sew his own neck back and managed to stay alive long enough to get medical attention after the battle was over

And even after all of that, that soldier manage to survive

Some had their limbs cut off, their hand was ripped apart, their feet blasted away by explosive but even in this condition, the Berserkers would not stop. 

One even crawl to the enemies and bite the enemies leg. 

Whether the enemies are a robot made of metal or a beast that have thick and thorny fur, the Berserks would bite even if it would break their own teeth

Amazingly enough, Freya marches toward the battlefield with five thousand Berserkers.
