Craving meat might just be an excuse, but his true purpose was probably to find a new food source for their newly established camp.
Actually, this was just Robinson William letting his imagination run wild; the other party hadn't lied. He spoke the truth—the special forces member had started eating bugs since he was a child, be it scorpions or centipedes, or even spiders and toads; he knew how to eat them and was also very skilled in various cooking methods.
The one who loved eating bugs as a child found that, as an adult, his chances to indulge became rare, especially after joining the special forces and achieving financial freedom.
But the special forces' culinary team certainly didn't prepare bug feasts, and during his leave, he couldn't find anywhere in the nearby cities where he could eat bugs.
So as he grew up, he found himself missing the carefree days when he could just catch bugs and cook them on the spot, what some might call a childhood filter.
