Modern warfare consistently brings unexpected developments, particularly with the discovery of advanced weaponry on the battlefield.
New designs and specialized tools frequently emerge, reflecting the ever-changing strategies of those engaged in conflict.
In the ongoing struggle between Ukraine and Russia, such findings continue to reveal the intricate dynamics of war.
A Ukrainian paratrooper recently acquired a VSS-M Vintorez sniper rifle, previously in Russian hands.
This modernized version of the Vintorez is equipped with a thermal sight and is known for its precision and unique capabilities.
Designed for stealth operations, it uses ammunition tailored for covert missions and defeating body armor.
The Unique 9x39mm Cartridge
The VSS-M operates with 9x39mm rounds, developed in the 1990s to combine suppressed firing with the ability to penetrate body armor.
Unlike earlier Soviet approaches that relied on adapting AK rifles, this cartridge was specifically created for specialized weapons.
It maintains a subsonic velocity below 340 meters per second to prevent the loud crack associated with supersonic bullets.
To achieve effectiveness while keeping the bullet’s speed below the sound barrier, developers increased the projectile’s weight significantly.
The 9x39mm round is built using a modified 7.62x39mm case and is fitted with a larger 9mm bullet weighing 250 grains, much heavier than standard 7.62mm ammunition.
Two primary variants of the ammunition include:
SP-5: Features a steel core enclosed in a full metal jacket, designed for armor penetration.
SP-6: Incorporates an exposed steel tip for added effectiveness, capable of piercing 8mm steel at a range of 100 meters but not suited for advanced ballistic plates.
The VSS-M’s design allows for silent, precise operations, making it an asset in missions requiring stealth.
Its capture by Ukrainian forces not only adds to their tactical options but also offers valuable insight into the capabilities of Russian forces.
