Panzer III Medium Tank

The Panzer III Medium Tank was the main German battle tank for the
first two and a half years of the Second World War, only beginning to
lose that status after the appearance of the Panzer IV Ausf F2 in
March 1942. Until then the Panzer III had been the only German
designed tank armed with a gun designed to penetrate enemy armour.

The Panzerkampfwagen III Ausf A was the first developmental version of
the Panzer III, but even though only ten were produced the type still
saw active service in Poland in 1939.

The Panzerkampfwagen III Ausf B was the second development version of
the Panzer III, produced during 1937 with a different suspension
system.

The Panzerkampfwagen III Ausf C was the third development version of
the Panzer III, and featured another attempt to improve the
suspension, the main weak point in the earlier designs.

The Panzerkampfwagen III Ausf D was the fourth and final development
version of the Panzer III, and saw a final attempt to improve the
suspension system first adopted on the Ausf B.

the Panzer III, after four pre-production series.

The Panzerhampfwagen III Ausf F was the second mass-production version
of the Panzer III and the first to be built in significant numbers.
http://www.historyofwar.org/articles/weapons_panzer_III_ausf_F.html

The Panzerkampfwagen III Ausf G was very similar to the previous Ausf
F, although most of the production run received the larger 5cm KwK L/
42 gun.
http://www.historyofwar.org/articles/weapons_panzer_III_ausf_G.html

The Panzerkampfwagen III Ausf H had been intended to be the first
version of the Panzer III to use the 5cm KwK gun when 759 were ordered
in January 1939, but the use of that gun on the majority of Ausf Gs
and the imminent arrival of the improved Ausf J meant that only 308
would be produced.
http://www.historyofwar.org/articles/weapons_panzer_III_ausf_H.html

The Panzerkampfwagen III Ausf J (5cm KwK L/42) saw the frontal armour
of the Panzer III increased in thickness from 30mm to 50mm, and was
produced with the 5cm KwK L/42 from the start.
http://www.historyofwar.org/articles/weapons_panzer_III_ausf_J_42.html

The Panzerkampfwagen III Ausf J (5cm KwK39 L/60) was produced after
Hitler insisted on the use of a longer gun in the Panzer III.

The Panzerkampfwagen III Ausf L was the first of two interim versions
of the Panzer III produced while attempts to fit a larger gun to the
tank were under way.
http://www.historyofwar.org/articles/weapons_panzer_III_ausf_L.html

The Panzerkampfwagen III Ausf M was the second of two interim versions
of the tank produced while attempts to fit a larger gun to the tank
were under way and was virtually identical to the Ausf L, but with the
addition of fording equipment, which allowed it to wade through four
or five feet of water
http://www.historyofwar.org/articles/weapons_panzer_III_ausf_M.html

The Panzerkampfwagen III Ausf N was the final production version of
the standard Panzer III, and the only version to be armed with the
7.5cm KwK L/24 gun.

The Panzerbefehlswagen III Ausf D1 was the first of a series of
command tanks based on the Panzer III, produced when it became clear
that the kleine Panzerbefehlswagen was not large enough for the role.
http://www.historyofwar.org/articles/weapons_panzerbefehlswagen_III_a...

The Panzerbefehlswagen III Ausf E was the second command tank to be
based on the Panzer III. It was based on the standard Panzer III Ausf
E but with the same modifications as on the earlier Panzerbefehlswagen
III Ausf D1
http://www.historyofwar.org/articles/weapons_panzerbefehlswagen_III_a...

The Panzerbefehlswagen III Ausf H was the third version of command
tank based on the Panzer III, and was based on the standard Panzer III
Ausf H.

The Panzerbefehlswagen III Ausf J or Panzerbefehlswagen mit 5cm KwK L/
42 was the first in the series of command tanks based on the Panzer
III to retain the tank’s main gun.

The Panzerbefehlswagen III Ausf K/ Panzerbefehlswagen mit 5cm KwK39 L/
60 was the last in the series of command tanks based on the Panzer
III, and the only one to be custom built with its 5cm main gun
intact.

on the Panzer III Ausf M, produced early in 1943.
