While the tank, which has received its greatest exploitation in the present
war, has under certain circumstances proved to be a formidable weapon, important
successes have been scored against it by artillery and tank-destroyer guns in
North Africa.
The tank has, no doubt, accelerated the speed of battle, helped to overcome
space, expanded the area of the battlefield, and increased the tempo of attack.
The experience of the Russians on the Eastern Front in combatting large
concentrations of German armor can be read with interest and profit. The
following article, a translation of Russian reports, deals principally with Russian
defensive measures against large-scale German tank attacks in the Orel-Kursk
sector.
* * *
a. Organization of the Defense
When beginning large offensive operations, the Germans lay the main stress
on tanks. They concentrate them on narrow sectors in order to effect a breakthrough
and then push through their motorized units and infantry. The problem
of the air force and artillery is one of direct support of the tanks on the
battlefield. Therefore, defense must be organized so as to repulse the combined blows of the
enemy, and especially his tanks. Experience has shown that the best results are
gained by the establishment of antitank defense areas.
From reconnaissance data the Russian commander determines the
sectors of primary and secondary importance in connection with possible tank
attacks. Where the terrain is the more accessible (level or broken, but without
deep ravines and swamps) there must be more antitank defense areas. During
reconnaissance, the commander determines the most expedient way of using
antitank guns and rifles; the location of the sector where they are to be used and
the character and type of the most advantageous obstacles under the given
conditions. It must be taken into consideration that not all seemingly impassable
sectors are actually so. Therefore, it is advisable to organize a system that
keeps the approaches to "impassable" tank areas within fire range.
In one case fifteen German tanks attacked the Russian advanced positions. The
left flank bordered on a ravine difficult for tanks to pass. The Russian
artillerymen easily repulsed three frontal attacks, but the Germans then blew up
the steep sides of the ravine and made it passable for tanks. Since the approaches
to the ravine were not covered by artillery fire, the enemy tanks broke through
and attacked the Russian battery from the rear. It was possible to restore the
position only by bringing in the antitank reserve.
The officer directly in command of the antitank defense areas must calculate
the amount of fire power and dispositions. The amount of fire power depends upon
the density of the tank attack on the given sector. If it happens that there are not
enough antitank defenses, the commander requests more from the higher authority. If,
however, the commander has only a limited number of antitank guns and rifles,
he must not scatter them throughout the defensive positions but must use them on
the main sectors.
Certain commanders, in determining the amount of antitank defense calculate
on the basis of the theoretical possible density of a tank attack. In reality,
however, the Germans have a very limited number of tanks on, many sectors.
Therefore, the expected and not the theoretical density of a tank attack must be
considered. In case of enemy reinforcements, the antitank defense areas may
have to be strengthened.
It is of great importance to have all approaches and intervals between defense
areas within range of converging defense fire. In addition, the fire power is
disposed so that any tanks, that may have broken into the defense area, may be hit.
b. Disposition of Antitank Guns and Rifles
Combat experience has shown the effectiveness of the following disposition
of antitank guns and rifles. Guns are placed at intervals of from 100 to 150 yards
and with distances in depth of from 200 to 300 yards. Antitank rifles are arranged
in squads. They deliver flank and oblique fire simultaneously with the guns. The
intervals between squads of armor-piercing weapons are from 50 to 100 yards and
the distances from 100 to 150 yards. With flanking fire, the distance between the
guns and rifles must not be over 100 to 150 yards.
c. Cooperation between Defense Areas
Constant communication is maintained between defense areas. There
should be complete and detailed agreement as to the methods of cooperation. The
distance between the guns on the flanks of the two defense areas should not be
over 500 yards. For antitank rifles this distance is reduced to from 150 to 200
yards.
d. Cooperation between Artillery and Infantry Commanders
The artillery commander establishes close contact with the infantry
commander of the unit in the region in which the antitank defense is
formed. Practice has shown the advantage of sending to the combat outpost a special liaison
officer, who, in case of a tank attack, determines the number and direction of
action and immediately reports to the defense area.
e. Artillery Tactics Against Tank Attacks
For repulsing large tank attacks, artillery of all calibers and heavy mortars
are brought into use. Batteries that fire from concealed positions adjust their fire
toward the approaches and antitank obstacles. In case of a tank breakthrough there
must be a very detailed agreement with the artillery commanders concerning
signals. When conditions dictate, divisional and, at times, heavy artillery may
be put out into open fire positions; these should be prepared in advance.
The antitank defense system as a whole is thoroughly camouflaged. Strict
discipline in firing must also be observed. It is not necessary to fire from all
guns at individual tanks or when they appear in small groups of three to four;
it is more advisable to allow them to come within range of direct fire. When the
enemy makes mass tank attacks the artillery opens fire at the greatest effective
range. In addition, mobile artillery of all calibers and firing from concealed
positions is used.
f. Antitank Reserves
Since the antitank defense cannot be equally strong throughout its whole
system, antitank reserves are of special importance. The reserves are allocated
to threatened sectors by army commanders. It is expedient to prepare in advance
firing positions for the reserves on sectors that are more likely to be pierced.
It is well for the next higher headquarters to prepare a plan of maneuver
for the antitank reserve. In this plan the composition, commander, line of possible
deployment and detailed routes are indicated. It is also well to have a signal
(known both to the army commander and the commander of the reserve group) for
calling the reserve.
g. An Example of Defense Tactics
German tank attacks in the Orel-Kursk sector were characterized by large
concentrated blows of several hundred tanks at a time on narrow sectors of the
front. Following the first echelons were the second and third, with the number
of tanks increasing each time. There were several instances when the Germans
brought over 200 tanks into battle at one time. The air force cleared the way for
the tanks, and the tanks in turn cleared the way for the infantry. During the very
first days the enemy suffered defeat in the battle for air supremacy. This left
the tanks to break through the defense without air support while facing our artillery.
Preceding a concentrated tank attack the enemy conducted combat reconnaissance
with small groups of infantry and tanks. This reconnaissance usually
began 30 or 40 minutes before the attack. Enemy reconnaissance columns consisted
of from 50 to 60 tanks and several self-propelled artillery guns on which infantry
men were carried. These detachments were usually supported by 10 to 15 airplanes. As
a rule the combat reconnaissance lasted not more than half an hour. In repulsing
these groups the minimum of fire power was used in order to keep the main artillery
positions concealed.
During the first battles the German tanks at times succeeded in piercing
our front line as much as a mile. In one case seven German bombers appeared,
escorted by fighters. While these planes began to bomb the front line, another
group of bombers coming in to take the place of the first group raided deeper in
the rear. Each group was followed by another as they worked their way deeper
and deeper into our defense positions. Tanks appeared simultaneously with the
third group of bombers. Forty of them deploying along the front and in depth,
rushed out at our front line, firing as they came. Several were disabled but a
part of them passed the trenches of our first line. Our infantry remained in its
positions and exterminated automatic riflemen who were carried on the tanks,
blew up two self-propelled guns and burned up one tank as it was crossing the
trench.
At this moment Soviet fighters appeared over the battlefield. Several
enemy bombers were shot down. The artillerymen made use of this and opened
up intensive fire on the tanks but 20 enemy tanks succeeded in penetrating to the
depth of half a mile, where they were met by self-propelled cannons. By this time
a great air battle was under way and 150 more German tanks came out against
our positions.
The lessons learned in the Orel-Kursk sector were that in fighting
reconnaissance and first echelon groups it is necessary to: (1) not only repulse
tanks but destroy them; (2) do this as quickly as possible since hundreds of tanks
follow; (3) solve this problem with the minimum amount of fire in order to keep
the disposition of all guns concealed.
The main object of our infantry is to isolate the German infantry from their
tanks, annihilate them, and protect our artillerymen from attacks. Our infantry
has always remained intact when they do not leave the trenches as enemy tanks
cross them. By remaining in the trenches they are able to separate enemy infantry
from the tanks and also destroy infantry when it is tank borne.
Battle experience shows that we must strike tanks with concentrated
artillery fire and from the air on their initial positions and at the approaches to
the battlefield. During the attack it is necessary to allow the tanks to approach to
be sure of hitting them. The Orel-Kursk battles show that even tank breakthroughs
are not dangerous if the enemy infantry has been separated from the tanks.
