I've noticed a lot of Polish stuff in your posts (niech żyje kraj cebuli) but never with bear Wojtek. If normal troopers would work with dogs I believe Bad Batch would definitely fit as the group that adopts a bear cub. Wrecker would totally play tug-o-war with him
Dogs are very prevalent in pop-culture in regards to military than any other animals (and those animals still play a major role in such institutions), however I saw lots of photos of cats on ships/navy vessels, also I’ve read about how rats help sappers clear minefields [LINK] - so I guess it depends on a possible primary job of an animal within the military (secondary is, always, boosting morale).
I mentioned corporal Wojtek in one of my earlier posts [LINK], however it was in passing as he wasn’t a focus of the story, so I’m not surprised it went unnoticed.
I have in my plans to draw Wojtek-inspired artwork with either Hardcase (he is a madman - he would totally wrestle a BEAR), Rex or Anakin wrestling such a creature. However, I think Wrecker would not only wrestle with the space!bear every chance he got, he would be the only clone trooper close enough to actually win such a play-fight!
I can see CF99 adopting such an animal (surprisingly... Crosshair became it’s primary handler and yes, he was feeding the cub milk out of the booze bottle like Wojtek was) but upon seeing how fast and how big it was growing they decided they all won’t fit in such a small vessel like Havoc Marauder. They considered giving the creature away to a space!ZOO (Tech’s idea). They didn’t even had a chance to do so, as 501st, upon seeing such a magnificent creature (and trained to do certain tasks!) just took the space!bear - it’s theirs now.
