SdKfz 222, or Leichter Panzerspähwagen (Light Armored Reconnaissance Vehicle), was a series of light four-wheel drive armored cars. It appears in most of the Call of Duty games taking place in World War II.
The Sd. Kfz. 222 makes several appearances in Call of Duty 2: Big Red One. In "The Desert Fox", one will appear after the player destroys the three Panzer IV tanks from the top of the cliff. The Sd. Kfz. 222 will drive up the cliff and shoot at the player. It can be easily destroyed with the Panzerschreck. Another is found at the end of the same mission shooting at Allied aircraft and preventing them from doing airstrikes on that position. The player destroys it with a satchel charge. Many later appear at the beginning of "An Easy Detail" driving after Roger's squad and shooting at them in the forest. They can be destroyed with multiple shots from the M2 Browning mounted on top of the Jeep.
It was also planned to appear in the scrapped levels set in Holland as one can infer from the winterized model variant present. There is also a model intended for multiplayer present in the model files, though lacking a machine gun. This model is seen in the loadscreen for Wetlands, its only confirmed appearance.
