Horny soldiers catching diseases from prostitutes was such a big deal that they had to make posters about it. You'd think that the lady lounging around with the words "VENEREAL DISEASE" on her lapel would be enough of a clue, but when you're talking about young hayseeds from the country, they're not quite that quick. She even looks so casual about it: "man, I'm bored. If only there was some guy I could infect, then I could kill some time until dinner. I wonder what G.I. Joe is doing right now..."
