I recently discovered a group called "Socks for Soldiers". They have been around for 8 years now and pride themselves on the hand-knit socks that they make which are then shipped in care packages to deployed soldiers. I think it's an awesome idea. Especially since I am a veteran myself. The yarn that is used is a specific type of yarn and the pattern and color both comply with military standards.
I cast on my first pair of these socks yesterday. It's a pretty simple pattern so I'm hoping that it knits up fairly quickly.
Here's a picture of my progress so far.
