The Field Artillery Mission is to destroy, neutralize, or suppress the enemy by cannon, rocket, and missile fires and to integrate all fires into combined arms operations.

Artillerymen are often referred to as "redlegs" for two reasons, dating back to the 1800's. Red appeared on two artillery uniforms, 1) when artillerymen wore uniform trousers with a two-inch red stripe, and 2) when red canvas leggings were worn by horse artillerymen.
