Children's Book about US Army

Two soldiers take a ten-ish boy on a tour of army training. I remember it involved (among many other things) pugil sticks and possibly the phrase "We train hard, so we have to eat a lot."

In my mind's eye it was a Little Golden Book, but I'm not sure about that. It was mostly photos- possibly black and white. I think it was printed in the 60s.

Thanks in advance.

Perhaps Do You Know What I'm Going to Do Next Saturday?, which includes a boy fantasizing about "playing" with Marines, including the lines "You have to keep eating if you want to keep going" and "Then I'll box another way. I'll box with sticks."

Yes! That's it. Thank you! :-)
