 The 5th Division commander, General Hung, later ordered tank-destroying teams be formed by each battalion, which included PSDF members who knew the local terrain and could help identify strategic locations to ambush tanks.They took advantage of the fact that the PAVN forces, who were not used to working with tanks, often let the tanks get separated from their infantry by driving through ARVN defensive positions.At that point, all alone inside ARVN lines, they were vulnerable to being singled out by tank-destroying teams.
