For whatever reason, I just read the above couple of posts about "straps" and "wallets in socks" from an imagined civilian eye view, and I had to laugh. Perfectly normal conversation amongst current and former service members, all in contemplation of how to keep one's shirt smartly taut and tucked, while ensuring socks did their fair share of the tug o' war. I always wondered who created the shirt stay contraption. Some Spartan or Roman sitting around saying, hey, if we attached our socks to our shirts/leather jerkins, we would look SO awesome. Yes, I know, Spartans and Romans were not big socks wearers, but someone dreamed this up, built it and sold it.
