The grim golem model is based on a type 2.2 frame and was designed execute advanced combat routines. Exclusively dedicated to close combat, its computing power is used by its optical jamming device instead of the traditional ranged combat files, otherwise useless to it.

It uses its speed and camouflage to progress under enemy fire. Once on its victims, it charges and annihilates its targets before vanishing again.

Grim golems are assassins and hunters. With their optical jamming devices, they can step out on the frontline without fear. There is no point establishing any complex strategy: they run straight for the enemy, drowning him in waves of fire before finally engaging him to give him a taste of their reaper blades.
