2A46M1

The 2A46M1 is a Russian 125mm smoothbore tank gun. It is a modernized version of the 2A46M gun and is the primary armament for many Russian and Soviet-era main battle tanks. The gun is designed to fire a variety of ammunition types, including armor-piercing fin-stabilized discarding sabot (APFSDS) rounds, high-explosive anti-tank (HEAT) rounds, and high-explosive fragmentation (HE-FRAG) rounds. It is also capable of firing anti-tank guided missiles (ATGMs) through its barrel, providing a significant increase in engagement range and effectiveness against heavily armored targets.

The 2A46M1 features a long barrel, typically around 48 calibers in length, which contributes to the high muzzle velocity of its projectiles. This high velocity is crucial for achieving penetration against modern composite armor. The gun is typically equipped with an autoloader, allowing for a high rate of fire and reducing the crew size required for the tank. Its advanced fire control system, when integrated with the tank's targeting systems, provides accurate fire on the move. The 2A46M1 has seen widespread deployment and has been a mainstay of tank forces for decades, undergoing various upgrades and adaptations to maintain its relevance on the battlefield.
