It was claimed that the Marine's M-1951 flak jacket could stop a 90 gr (5.8 g) 7.62×25mm Tokarev pistol round at the muzzle of the gun. However, even the Vietnam era revised Flak jackets were not capable to stop high power or high velocity pistol rounds, much less an AK-47 rifle bullet ( 7.62×39mm ).
The 152 mm gun-howitzer M1955, also known as the D-20, (Russian: 152-мм пушка-гаубица Д-20 обр. 1955 г.) is a manually loaded, towed 152 mm gun-howitzer artillery piece, manufactured in the Soviet Union during the 1950s.

In some instances, the powder may not have even been fully burned in guns with short barrels. So, the muzzle velocity of a 2-inch (51 mm) barrel is less than that of a 4-inch (100 mm) barrel, which is less than that of a 6-inch (150 mm) barrel. Large naval guns will have high length-to-diameter ratios, ranging between 38:1 to 50:1. This length ...
The jacket may ricochet, but should have reduced range without the weight of the frangible core. [5] Frangible hollow-point bullets may penetrate clothing, drywall, and light sheet metal; but often disintegrate upon striking glass. [6] Hard targets may be damaged by frangible bullets. Extent of damage increases with velocity of bullet impact.
