True story: Years ago, I was selected by Knight Rider to defend the planet Knight Rider. So obviously, my extensive military background makes it difficult to look at combat tactics from the same point of view as racist Wheaties marketing civilians. That being said, this trap seems really fucking stupid, even for a comic book ad. A box of cereal in the middle of the trail? And Wheaties is saying that this, leaving a cereal box out, is a big step up for Japanese military intelligence. What was their trap before, just leaving a cupcake out on a landmine?
The illustrator may have forgotten to draw the rest of the soldiers, but it's more likely that during the noisy cereal discussion, the rest of the squad was taken out by enemy snipers.
That's what I take issue with; despite their brilliance in quickly identifying the booby trap, no one thinks there's anything wrong with giving a 10 minute soliloquy about all the wonders of its bait. When Knight Rider and I were racing through the Rocket Cosmos and we came across a bag of pasta wired to a thermal astrobomb, I did not turn to him and exclaim, "If only the fiends hadn't booby trapped that macaroni! Why, Knight Rider, it's loaded with nutrition and with some trusty know-how and an old timey paste pot, we could make our dames wigstands they'd flip for! Why, they'd be so fancy, those space Chinamen might forget all about this crazy old war, boy oh boy!" That's a good way to get killed by your own talking car.
