We find ourselves in a jungle, the canopy is tight and green, as the main imperial line advances, ripping down everything in their path to get the Ork manufacturing facilites. The Orks started raids and the imperials countered this with their own recon groups in the jungle. Most of which never returned.

The lone Guardsman is running, running from all that he has ever feared, death. Typical for any simple Guardsman in this grimdark universe. As he runs he suddenly hits a large clearing. Mangled trees and leaves that no longer resemble leaves are everywhere.
The Guardsman looks right and sees trees standing upright more for every passing yard. To his left stands a mighty Space marine, in his red battle suit he stands out like nothing else. The Guardsman hesitantly approaches him.

"Mighty warrior, tell me what has happened here."

"Lowly guardsman," The space marine replied, "I am fighting for the emperors will. Five days I have stood and repelled any attack on myself with my trusty heavy bolter."

"Five days?" The Guardsman was puzzeled as he believed the weapon would be out of ammo long before that. "Tell me brave marine. What are you shooting?"

"ZEAL!" The marine yelled his voice distorted through his Vox. "Now get down Orks approach us."

An ork reconisance group rushed through the very edge of the clearing and spots the marine instantly. "SPACE MEHREEEEN!" They yelled.

"WRAAAAAAAAAAA FOR THE EMPEROR" The marine cried. "DKAKAKAKAKAKAK!!!!!!!!!!!!!"

"BOYS HE SHOOTAN RUN BACK TO THE BIG MAN!!!!!!"

"Yeah." The marine said as he petted his weapon. The Guardsman shocked could not move, could not speak, could not think. And could not warn the space marine as the Baneblade ran both of them down.
