The "Mocking Bird" is a light artilery used by the U.S.O.S. It maybe light, but has its advantages, it is easily yowed by most vehicles due yo its size, heck, even the medical jeep can carry it. It was given its name due to the fact that the enemy mocked it size, then, when they were hit by the shell, they stopped mocking it.
