They were the men trained to be Platoon Sergeants and Squad Leaders in Infantry Companies in Vietnam. During the Vietnam War, Ft. Benning trained and graduated over 26,000 men to fill the slots of Senior NCO's who were either retiring or being killed and wounded in Vietnam. The program went from the fall of 1967 to March 1972. We lost 1,114 men in Vietnam. The group earned 4 Congressional Medals of Honor, 18 Distinguished Service Crosses, 51 Silver Stars and Countless Bronze Star Medals with Valor and a ton of Purple Hearts. Check out the NCOC honor wall on the site.
Earthpoint. This is an excellent site that allows you to convert military grids into latitude/longtitude that can be pasted into google earth. Select "convert coordinates" on the left and then enter the grid in the "position" cell. Use the the grid zone designator (the northern maps are 48Q and southern are 48P) and the 100,000 square (such as YD or XT) in front of the actual coordinate numbers. These items are in the lower right of the 1:50,000 mapsheets. Example is 48QYC5681 for Camp Evans. This tool does not require a subscription.
