'''Artilleriyskiy Tyagach Lyogkiy''', or '''AT-L''' ({{langx|ru|Артиллерийский Тягач, Лёгкий (АТ-Л)}}, meaning ''light artillery tractor'') was a [[Soviet Union|Soviet]] [[Cold War]] era artillery tractor. The vehicle has the same cab as the [[ZIS-150]] and [[ZIL-164]] trucks, but has a different front end and grille similar to that of the [[GAZ-51]] truck.<ref name="[48]">{{cite web |title=Военная техника с Одкарленда |url=https://detroit-diesel8.livejournal.com/308196.html |access-date=12 August 2021}}</ref>
==History== 
The light artillery tractor AT-L was created in [[1947]] by the design bureau of the [[Kharkiv Tractor Plant]] . Due to the insufficient power of the only suitable diesel engine, it was necessary — for the first time in Soviet practice — to resort to a more efficient but expensive and maintenance-demanding planetary transmission without side clutches, similar to that of the Panther tank.

To overcome a one-meter-deep ford, as required by the military, improve cross-country ability in deep snow, and reduce overall weight, a welded load-bearing box-shaped hull was designed for the first time instead of a frame. Unfortunately, operational experience in the military revealed that this design did not pair well with the original running gear featuring six intermediate-diameter road wheels (due to its structural similarity with the [[Ya-12]], the tractor was even mistakenly designated in the West as Ya-14): the mounting of the support rollers could not transfer the high loads from oscillations of the upper tracks at high speeds to the thin-walled hull. As a result, the running gear had to be redesigned with five large-diameter road wheels, which appeared somewhat awkward but were much heavier. This was done in 1954–1955, and from 1957, the HTZ-5A (also known as ATL-5A) modification was produced. It replaced the more conservative development of the Ya-12 — the [[M-2 (tractor)|M-2 tractor]] — which had been in production from 1948 to 1955 and is depicted in all illustrations in this article.

Various specialized vehicles were mounted on the AT-L chassis over time, including artillery reconnaissance radars [[SNAR-1]], [[SNAR-2]], and [[ARSOM-2]] (ARSOM-2P), the special van 711, a fire-fighting foam lifter, a tracked bridge-layer, and others. For these purposes, versions of the tractor were produced without cargo platforms, towing devices, winches, and brake pneumatic systems for towed artillery pieces — these versions were designated as HTZ-23, HTZ-27, and HTZ-39 (from 1957: HTZ-23A, HTZ-27A, and HTZ-39A). Bulldozer equipment OLT or OLT-M could also be mounted on the AT-L.

It was produced until 1967 in several modifications and earned respect in both the army and the national economy. It was widely used for the development of hard-to-reach areas of the [[USSR]], and by early 1975, AT-L and GTT all-terrain vehicles formed the backbone of the off-road vehicle fleet of Siberian industrial enterprises.<ref>M.
