Notes on Table 4.3 (Continued) a-The damage did not extend to the surface and is not comparable with other rounds; the sides of the original charge hole were damaged up to average slant distance of 5.6 ft from the center of gravity of the charge. b-Crater shape was estimated; the breakthrough volume is not included. c-Average of eight measurements scaled from the vertical crater sections.
