The German 88-mm. dual-purpose AA and AT gun has been a vital factor in Rommel's African
campaigns. However, this gun is only one element in the excellent antitank organization
of the Germans and should be viewed in its proper perspective.
In accordance with German Army principles, each combat unit, from the smallest to the
largest, is so organized, armed, and equipped as to be tactically self-sufficient. Antitank
protection is vital to the successful accomplishment of a combat mission; therefore, suitable
antitank weapons are provided for each unit. These weapons are used in accordance with the
German doctrine of antitank defense, which may be summarized as follows:
Staffs, troops, and supply echelons must be prepared for a tank attack at all times. Careful
ground and air reconnaissance and map study assist in indicating the avenues of approach feasible
for hostile tank attacks. Certain terrain features are natural obstacles to tanks and must be
used to full advantage. The favorable avenues of approach must be protected by antitank
guns, artillery, mines, and tanks.
The antitank units, organically a part of infantry regiments, battalions, or companies contribute
their fire power to the support and protection of their respective organizations. Those antitank
units which are organically a part of corps and divisions, constitute a reserve force which, because
of their mobility, can be rushed to decisive areas as determined by the general situation.
Early information relative to hostile tanks permits timely and coordinated defensive measures. All
reconnaissance agencies must be required to report immediately tank information to the commander and
to the troops specifically threatened.
Certain situations may require the attachment of additional units to antitank battalions such as
signal, engineer, and infantry troops.
Antitank protection has been provided for in each of the units, from the smallest to the
largest; furthermore, the amount of protection is being steadily increased.
Each infantry company is protected by a section of 3 AT rifles. In Africa, each
company of a light division was reported to be equipped with two 76.2-mm. captured
Russian field guns for antitank use. (However, see this publication, No. 3, p. 5). Each
infantry battalion is protected by 9 AT rifles.
Each regiment is protected by 27 AT rifles and by an AT company which
has 3 platoons, each armed with four 37-mm. AT guns (total 12), and
one platoon of four 20-mm. rapid fire AA-AT guns.
A trend toward substitution of the 50-mm. AT gun for the 37-mm. AT gun
is progressing rapidly.
The infantry division is protected by 81 AT rifles, forty-eight 20-mm. AA-AT guns, and
seventy-five 37-mm. or 50-mm. AT guns. The divisional AT battalion has 3 companies of
twelve 37-mm. AT guns each and one company of twelve 20-mm. AA-AT guns. One
AA battalion of twenty-four 20-mm. AA-AT guns and nine 37-mm. AA guns, or
of thirty-six 20-mm. AA-AT guns may be attached.
The motorized division is protected by fifty-four AT rifles, twelve 20-mm AA-AT guns,
fifty-four 37-mm. AT guns, and nine 50-mm. AT guns. The motorized AT
battalion has 3 companies of eight 37-mm. and three 50-mm. AT guns
and one company of twelve 37-mm. AA-AT guns. An AA battalion
of twenty-four 20-mm. AA-AT guns and nine 37-mm. AA guns may be attached.
The armored division is protected by high velocity guns mounted in the tanks (totaling one hundred
seventeen 37-mm. or 50-mm. high velocity guns), by an AT battalion
with twelve 37-mm. and eighteen 50-mm. AT guns, or an AT battalion
with twenty-four 47-mm. self-propelled AT guns each mounted on a Mark I tank chassis
with a three-sided armor shield, and by an AA Battalion with thirty-three 20-mm. guns.
A mobile AA battalion from the air force is often attached to a division when additional
protection is required. This battalion contains 3 heavy batteries of 88-mm. AA guns, each
battery consisting of four 88-mm. AA guns and two 20-mm. AA guns; 2 light
batteries, each consisting of fifteen 20-mm. AA-AT guns and
four 60-cm. searchlights; 1 searchlight battery consisting of nine 150-cm. searchlights
and 6 sound locators.
Generally speaking, antitank weapons are of two types: either single-purpose, such
as the 50-mm. AT gun, or dual-purpose, such as the highly
effective 88-mm. AT and AA gun. The characteristics of the most commonly
employed AT weapons may be summarized as follows:

It is a high velocity dual-purpose gun equipped with a shield and has been
used most effectively in the African campaigns. Its effectiveness is
due to (1) mobility - towed on trailer by half track with ammunition in rear
and can go into position very quickly by use of outriggers and demountable
spade; (2) flexibility - (when not firing from trailer), can change from AT to AA fire
in 5 to 6 seconds, traverse 360° and has specially trained crews who are able to take
full advantage of its capacity to fire on rapidly moving targets; (3) high velocity - has
penetrated all types of British tanks and also our own light and medium tanks.

In conclusion, the German Army has developed a system of balanced antitank protection which
complements its system of antiaircraft protection. All units from the company to the division
have an all-around "cubic space" (three-dimensional) protection against the greatest threats
of modern warfare, the tank and the airplane.
