Type 89 AFV hull which opens into the troop compartment. The gun can traverse through 360 degrees and can be elevated to an angle of 90 degrees. Two oblong roof hatches and a large rear door provide access to the troop compartment. On either side of the forward hull, a cluster of four 76 mm smoke grenade dischargers is mounted. The vehicle is amphibious, a folding trim board stowed at the front of the hull needs to be raised, and the vehicle can then propel itself in the water using its tracks. Standard equipment includes an NBC system, a Type 889 or CWT-167
Degrees of freedom (mechanics) would have a combined DOF that is the sum of the DOFs of the bodies, less the internal constraints they may have on relative motion. A mechanism or linkage containing a number of connected rigid bodies may have more than the degrees of freedom for a single rigid body. Here the term "degrees of freedom" is used to describe the number of parameters needed to specify the spatial pose of a linkage. A specific type of linkage is the open kinematic chain, where a set of rigid links are connected at joints; a joint may provide one DOF (hinge/sliding), or
