Sharp-eyed armor experts will notice that some of the US M-113 armored personnel carriers in Iraq are sporting Vietnam-era ACAV (Armored Cavalry) shield kits for their commander's cupola and the side gunners'. While it's impossible to tell exactly where these relics came from, a reliable source recently checked the "back 40" behind a National Guard armory and found shield-shaped holes in the snow where he remembered seeing some ACAV kits rusting away a few months ago. While circumstantial evidence at the moment, it's just further proof that the "Legacy Force" is far from irrelevant. - Adam Geibel
