In this wild world of ours everything can be divided into one of three categories: things that don't make sense, things that do make sense, and shit that's magic. And this is one of those magical joints: Chewbacca riding a giant squirrel fighting Nazis with his iconic Bowcaster (full-size version HERE). It was created by deviantARTist gamefan84 per a request and if I were Chewy I'd be busy pinning Nazi heads together with Bowcaster bolts and not bucking my mount and moaning like I just won a carnival prize. Cause as it stands it looks like he's about to lose his mount and get stick-grenaded in the face. Han will never want to pet you again!
Thanks to Julian, Blaqk Panda, HeischenStien and wes g, who all would have shot first and don't care who knows it.
