I figured that I'd post this link on here because I didn't really know where else to post it.
Army Library Program Reference Center
The above link is, unfortunatly, only for military members or those who have Army Knowledge Online (AKO) access. It contains lots of useful information not to mention every Chilton's manual 1954 to present. It's a great tool...just utilize your work printer so you don't use all your own ink...not that I've ever done that.
