All-New Firefly #4

I cannot write a synopsis based on these pages because they appear to be from a Golden Age comic book (likely from the 1940s based on the style and content), not from "All-New Firefly" #4 (2022) by Boom! Studios as stated in your prompt. The cover shown is "All-New Comics" #4, a public-domain Golden Age title, featuring a story about American soldiers battling Japanese forces and encountering natives in a jungle setting, as well as a separate story involving space travel and a demagnetizer weapon. The anachronism between your stated source and the actual material prevents me from providing the requested synopsis.
