It weights about 7.4 tons with a crew of three; A commander/ gunner, a mechanic/ machine gunner, and a driver. The commander loaded and trained the 37mm Type 94 main battery. He also had a secondary battery of a 7.7mm Type 97machine gun fired out the rear of the turret. The mechanic/ gunner had a 7.7 mm Type 97 machine gun fired from a flexible mount in the forward hull. The turret would only rotate in a 45 degree arc requiring the 7.7 mm in the rear of the turret to provide some but highly inadequate protection to the rear.
