One of the most interesting military vehicle developments of the German Reichswehr and Wehrmacht was without doubt the halftrack tractors. Basing on experiences from the First World War the development started at the end of the 1920’s. From the six types of un-armoured halftrack vehicles (1 tonne / 3 tonne / 5 tonne / 8 tonne / 12 tonne/ 18 tonne) developed from the early years and beginning in 1930, the main vehicle was the 8 ton halftrack Sd.Kfz. 7.
This vehicle, which served in many differing deployments, and which had the highest production numbers, was produced from 1935 – 1945. Dr. Nicolaus Hettler, who has already described the halftrack vehicles 18 tonne Sd.Kfz.9 (N&B 12) / 12 tonne Sd.Kfz.8 (N&B 16) und 3 tonne Sd.Kfz.11 (N&B 20), continues these series with the halftrack 8 tonne Sd.Kfz.7.
