One of the many Sd.Kfz.10 half-track modifications produced by Demag company as mobile Flak 38 anti-air gun platform since 1939.
This fully metallic integral body half-track was propelled by a double differential tracked chassis with brakes (forward steering wheels don't have brakes) and had a custom metallic platform where the gun was installed.
20mm Flak 38 anti-air gun was a modification of the earlier Flak 30 design with doubled rate of fire and improved two-speed lateral and vertical aiming system, its production started in 1938.

Remove gunsight shield
Removing the gunsight shield gives the gunner a slightly wider field of view.
Remove both gun shields
Gun shields are completely removed for an improved field of view.
