This annotated topographic map marks the loss coordinates of MACV-SOG reconnaissance team member Robert F. Scherdin, listed Missing in Action, in the same tri-border area where Robert L. Howard earned the Medal of Honor while serving with Recon Team Vermont. Compiled from U.S. military survey sheets, the map reflects the meticulous historical research conducted by veterans and historians to document the covert cross-border missions of MACV-SOG during the Vietnam War.
