OVERVIEW: 125mm APFSDS-T (Armor-Piercing Fin-Stabilized Discarding Sabot – Tracer) ammunition for the 2A82-1M smoothbore tank gun is designed for long-range precision penetration of heavily armored targets. It is optimized for defeating modern main battle tanks and armored vehicles equipped with advanced composite or reactive armor.

DETAILS: This type of round consists of a long-rod penetrator—typically made from tungsten alloy or depleted uranium—encased in a lightweight sabot that is discarded upon muzzle exit. The penetrator is fin-stabilized for aerodynamic accuracy and includes a tracer for flight tracking. Fired at extremely high muzzle velocities (approaching 1,800–2,000 m/s), 125mm APFSDS-T rounds deliver deep, concentrated penetration through kinetic energy alone. Ammunition designed for the 2A82-1M features enhanced propellant charges and advanced sabots to take advantage of the gun’s high pressure and lengthened chamber.

ROLE SUMMARY:
Category: Tank Gun Ammunition
Primary Use: Anti-armor
Function: Kinetic energy armor penetration
Strong Against: Modern main battle tanks (MBTs), AFVs with composite or spaced armor, Static hard targets such as bunkers.
Weak Against: Infantry or soft targets, Obscured or defiladed positions, Vehicles protected by advanced Active Protection Systems (APS)
Platform: Modern MBTs with 125mm smoothbore guns
Integration: Optimized for 2A82-1M (e.g., T-14 Armata), backward compatible with some earlier systems with limitations
