Read "Black Hawk Down" to see what some of the SF and Rangers think of the .223. An AR was high on my wishlist until I read this book. Its still there but not at the top anymore.
If you read the book CAREFULLY, you would see that the Sammies sometimes shrugged off 7.62x51 rounds from the M60s too...it was a function of them being whisper thin, wearing loose clothes and being high on drugs, not of caliber.
