Marines exterminating genestealers, by Gabriel Navarro Romero

Original artist's page.

Edit: To the person who accused the art of being AI generated, it was posted in 2018. The major AI generators were not available until the 2020s. The artist posted this on their personal low traffic page so had nothing to gain. Along with this picture there are work in progress shots of other digital art. Please do not accuse random artists of passing off AI generated art as their own in a witchhunt.
