This is a self-propelled howitzer 155mm built by Soltam of Israel on the chassis of the M4 Sherman tank, which Israel had many of at the time. The howitzer is mounted in a fighting compartment consisting of a raised superstructure running from the rear to the middle of the vehicle. The driver is seated at the front left with a bullet resistant windshield to his front and sides. The commander is to the rear of the driver on top of the raised superstructure. There is a cupola to the right of the commander with a machinegun. The crew enters and leaves via a hatch on either side of the vehicle. A longer-length barrel is available which allows +10% range, but this version is very rare. The engine in the L-33 has been replaced with a more powerful model to cope with the increased weight.
