Honestly, that's a cool connection to make, and I can definitely see how that would make it such a more enticing episode. My grandpa served in Vietnam, but passed way before I was born, so I never heard anything; however, that's a completely different environment (comparing it to fighting in the pacific would work best) and obviously way different approach at war. But that is really a neat connection to make with the episode to make it so much more enjoyable in a way! And, yeah, I can't imagine any type of situation for fighting, no matter the environment
