The suspension itself was liftable thus allowing to use the car as a normal truck as well. In contrast to the similar GAZ-65, tests proved rather satisfying, so roughly 4,000 of the new »ZiS-33« were produced in the late 30's.

The ZiS-33 was an attempt at the end of the 1930s to develop a part time half-track variant of the ZiS-5, designed to allow a modified ZiS-5 truck to be converted to a half-track as required for operation on soft

用吉斯汽车改装的半履带车的型号有ZIS-22M、ZIS-33和ZIS-42M，其中ZIS-22M在二战前就已经生产，至1940年生产了约200辆，而ZIS-42M则是二战中（1942年）为了解决苏军火炮在恶劣路况上的机动而临时改装而成。

2023年10月26日 · 生产型的ZIS-33大部分在二战中损失或拆除了履带式行走装置改回了普通的ZIS-5卡车，目前仅有一辆经过修复的实车存世。

The Soviet ZiS-6 was an adaptation wit a 6x6 chassis of the ubiquitous ZIS-5, with better characteristics; About 90,000 were built from 1936 to 1948.

该车型是在ZIS-5卡车的后轴部分添加了履带式行走装置而成为半履带车，从而提高越野行驶的性能。 这个行走装置可拆卸，必要时可以拆除并还原为普通卡车，从而提升速度，降低油耗。

In the late 1930's, the Moscow »ZavodImieni Stalin« (»ZIS«) combined a simplistic track suspension with an ordinary ZiS-5 truck. The suspension itself was liftable thus allowing to use the car as a normal truck as well.

ZiS-33, 1940, half-track set for ZiS-5 of the Red Army, 4539 built, 43k 1941 photo, showed bad characteristics, rebuilt back to ZiS-5, 44k photo. ZiS-34, 1940-1941, short wheelbase ZiS-6 shassis, 16 built, all used for BA-11

As with the better known ZiS-33, the suspension itself was liftable thus allowing to use the car as a normal truck as well. However, tests proved little satisfying, so only a handful of the new »GAZ-65« were produced and GAZ soon switched production to the better suited GAZ-60.
