T871

T871 is a designation used by the United States Army for a specific type of ammunition. It refers to a 120mm mortar round, which is a type of artillery shell designed to be fired from a 120mm mortar tube. The T871 round is a high-explosive (HE) round, meaning it is designed to cause maximum damage through the explosive force of its payload.

The T871 round was developed to replace the older M19 mortar round, which had been in service since the 1950s. The T871 was introduced in the 1980s as part of the Army's modernization efforts to improve the effectiveness and lethality of its artillery systems. It is used in a variety of roles, including direct fire support, indirect fire support, and area denial.

One of the key features of the T871 round is its improved lethality. It has a higher explosive fill, which means it can cause more damage to targets. It also has a longer range than the M19 round, allowing it to engage targets that are farther away. The T871 round is also more accurate, thanks to improvements in the mortar system itself.

The T871 round is used by a variety of units within the U.S. Army, including infantry, cavalry, and artillery units. It is also used by other countries that have purchased the M252 mortar system, which is the system used to fire the T871 round. The T871 round is an important part of the U.S. Army's artillery arsenal, providing a versatile and effective option for a variety of missions.
