A couple good sites to check are www.rjsmith.com and www.bravecannons.org At the first he has info on how to order the regular coast guard type maps which are close to our flight maps.

The 4th Infantry site has a link to the 1/8 web site. They have a great grid map of Yankee Bravo in the Plei-Trap Valley from Mar.1969.

The nicest looking maps I've found were at the second site. This is the 1/92nd Field artillery.
