A German View of Teploye: Tanks

"103rd Artillery Regiment, 4th Tank Division
1st Squadron, Squadron commander

Tactical experience of artillery in offensive and defensive battles south of the city of Orel from July 5th, 1943, to August 18th, 1943

1. Overall tactical experience

1. The battles were characterized as very fierce, with a large amount of vehicles. Both sides used powerful aircraft and tank units, and the Russians had especially powerful artillery. Neither side achieved decisive success on the offensive.

However, on the defensive, both sides managed to achieved significant success. Just as the offensive actions of the division before July 11th led to a sudden and unexpected decrease of our infantry's fighting ability, the Russians, despite their notable advantage in tank, infantry, and artillery units, took heavy losses. The cause of this, in my opinion, is because neither side had in their possession decisive offensive weapons.

At the moment, neither the PzIV with the long gun or the T-34 demonstrates an advantage over the other.

L-60: Scandinavian Tank Revolution

Having fought its last war in 1814, Sweden ended up one of the few European countries that avoided participating in either World War. Nevertheless, the Swedes always paid careful attention to their army's weapons. Despite its neutrality, Sweden often preferred weapons of German origin. This applied to tanks as well. Even the Strv fm/21, the first Swedish tanks, were really German LK.IIs. Ten of these tanks were built at AB Landsverk in Landskrona, which became the Swedish tank development center for decades to come. The Landsverk L-60 was born here, some elements of which were a real revolution for tank development in the 1930s.

World of Tanks History Section: The British Devil and His Brothers

No one could have guessed on September 15th, 1916 that many military theory books would become obsolete in an instant. The first tank entered its baptism by fire, and an unnamed German's cry "The devil is coming!" announced the coming of the new god of war.

French and German tanks came after British ones, but the "rhombus" was the first of the first. Nine tanks belonged to this family. Some of them made it in time for the war, others remained prototoypes. Episodes collected in this article will briefly describe the "rhomboid" family.

Anti-Tank Rifles in 1943

"Is there a reason to keep anti-tank rifle companies in infantry regiments?

Combat experience shows that keeping an anti-tank rifle company in an infantry regiment as a permanent unit is not sensible for the following reasons:
  1. The summer battles of 1943 are characterized by new types of tanks from the enemy's side. These tanks have thick armour and powerful guns up to 88 mm in caliber. These vehicles include the Ferdinand SPG and Tiger and Panther tanks. Light tanks, armoured cars, and tankettes are used as an exception. The anti-tank rifle is only effective against the Ferdinand and Tiger at a range of 150 meters and closer. Such a close distance allows the enemy to destroy infantry, machinegun nests, dugouts and bunkers at close range, ensuring maximum effectiveness. This situation requires a light weapon that could reliably destroy tanks and SPGs at 600-700 meters. The anti-tank rifle does not meet these requirements.

Narev Foothold

"Conclusions regarding the combat actions of the 80th Guards Idritsa Order of the Red Banner Heavy Tank Regiment from October 4th to 25th, 1944, in battles for the Narev Foothold
  1. In battles at the Narev Foothold, the 80th Guards Heavy Tank Regiment was used in both attack and defense, In defense, the regiment was used for combat with enemy tanks, deflecting their counterattacks. Heavy tanks from the regiment cooperated with tanks from the 17th Tank Brigade. IS-122 tanks fired at enemy heavy tanks from 2 km away, and T-34s fired at closer, less important targets.

TACAM T-60: SPG, Transylvanian Style

Romania joined WWII with a very marginal tank force, both in numbers and capability. The first battles on the Eastern front showed that their tanks were incapable of engaging Soviet medium tanks, let along heavy ones. The Romanian army was in desperate need of new more powerful anti-tank means. In a very short amount of time, they could only be built on captured platforms.

Romania only have one tank unit in the summer of 1941: the 1st Tank Division. It consisted of the 1st and 2nd Tank Regiments, reinforced by two regiments of motorized infantry, a motorized artillery regiment, a recon battalion, and a sapper battalion. The 1st Tank Regiment was equipped with Czechoslovakian S-II-aR (an export variant of the LT vz. 35), 126 of which were purchased in 1938-1939. These tanks served in the Romanian army under the index R-2. The 2nd Tank Regiment consisted of French Renault R35 tanks. In August-September of 1939, 41 tanks were received from France. 34 more tanks arrived from Poland: these were tanks from the Polish 21st Battalion that crossed the Romanian border on September 18-19th, 1939. If the R-2s could at least fight Soviet light tanks, the R35s with their short barreled guns were helpless against any armoured opponent.

World of Tanks History Section: Crushing the Tarnopol Fortress

The main purpose of new IS-2 heavy tanks that appeared in the Red Army in 1944 was the destruction of German pillboxes with their 122 mm guns. Fighting enemy tanks was not a priority. However, plans and forecasts rarely work in war. The IS tanks got a chance to test themselves against enemy armour soon after they arrived on the battlefield.

This happened in the spring of 1944, during the Proskurovo-Chernovtsy operation. In addition to their other objectives, the Soviet forces had to surround the German 1st Tank Army. Colonel-General Chernyakhovskiy's 60th Army participated in this task. One of the first targets in its path was Tarnopol (modern day Ternopol). Hitler declared it a Festung: a city-fortress that German forces had to hold until the last man. On April 11th, it was time for the defenders to carry out that order.
