A hangar in Solis. Two marines were sitting on some crates and looking at rhino transport.

One of them was techmarine, and other was tactical marine. Techmarine marine say:

"Look, I want to add an assault cannon to the rhino"

(Just a cannon"

Tactical marine glanced at him and said:

"Why?"

Techmarine answered:

"I don't know... It's like something leading me"

He stands up and walks to rhino, tactical marine asked, jokingly:

"The Emperor?"

Techmarine grabbed assault cannon and asked:

"Plasma cannon, or assault cannon?"

*Just a cannon*

"What plasma cannon? Why?"

"Just agree, don't argue"

"... Definitely the Emperor"

Techmarine begins to add heavy stubber.

heavy bolter

*Just a bolter*

and grenade launcher to the rhino.

Tactical marine was looking at this and asked:

"Claw, what are you doing?"

"I understand. Dark mistress had expanded grimm hordes. Peoples are dying, and we, as defenders of humanity must act. It's our main objective"

*5 minutes later*

Two of them were standing in the forest, with their rhino between them. Techmarine said:

"We are going to fight"

"With whom?"

Asked tactical marine. They were interrupted by the biggest horde of grimm they ever seen. Two of them gasped and entered the APC.

"That's our enemy! Grimm!"

Yelled techmarine. He started the engine, as tactical marine opened a hatch and stand on gunner place. He begins to fire at grimm with all he has: heavy stabber, heavy bolter and assault cannon. Techmarine begins to circle around the horde as tactical marine continue to fire at them. Tactical marine saw flying grimm and said:

"Shitty birds, they are"

"I sense no smell... Ah, you're talking about nevermores"

"I will shoot them with my hands"

He exits the vehicle with heavy bolter and started to shoot at nevermores. As he shot down all nevermores, they continued to destroy grimm horde.

"Firing assault cannon!"

Yelled tactical marine and started to shoot, tearing down grimm flesh. They were fighting nonstop for five hours, until all grimm were dead. They exits the APC to look around. All grimm were dead, and forest was devastated from constant firing. Techmarine yelled:

"Hooray! We did it! We stopped the grimm!"

Tactical marine bonked him in the head and said calmly:

"Hooray..."
