A very noteworthy aspect of Soviet high explosive ammunition is
the use of cast iron in both mortar end artillery H.E. shell as seen
from the data shown in Table Vi. The extreme brittleness of cast iron
enhances the fragmentation characteristics of this Material; a shell
of cast iron may produce up to 20 times as many fragments upon detonation as a similar shell made from forged steel. The fragments recovered
from one detonated 82 MM wortar shell are shown in Figure 11. This shell,
for exauiple, produced more than 10,000 fragments upon detonation. Although, of course, a very large proportion of these fragments are fines
weighing less than 2 grains (approxiimately 7500 fragments Pre in this
classification), a very large number of these fragments may be effective
at casualty producing agents. Even very tiny fragments are capable of
producing severe casualties as weil as deaths as attested to by the
surveys made by medical teams in , Korea during the periods when field
trials of experiental body armior garments were conducted prior to the
standardizvtion of this type of cquipment.
The 82mm Soviet wortar shell also produced approximately i600
fragments weighing from 2 to 5 grains, 850 fragments weighing from 5
to 10 grains, 700 fragmaents weighing l0 to 25 grains, and l00 fragments
weighing 25 to 50 grains. Fragments in these weight ranges are particularly effective against personnel.
Competitive firing tests of the Soviet 82 MM cast iron and the
American 81 MM M43A1 forged steel mortar shell have been conducted at
Aberdeen proving ground where the shell were detonated in the center
of 1" pine boards arranged in semicircles of 20 foot and 40 foot radii.
The following results were obtained:
82 MM Soviet 81 MM American
Mortar Shell M43A1 mortar Shell
20' radius
Total hits 5891 734
Total perforations 1435 333
40' radius
Total hits 2513 277
Total perforations 824 102
I believe this data directly contradicts what Mobius is claiming.
