Shermans in the Mud

Few people interested in WWII armoured warfare haven't seen this video depicting Swedish trials of a Sherman, a Churchill, and a Panther in difficult off-road conditions. Many people, after having seen this video, readily claim that the Sherman had inferior off-road mobility to the Panther. Certainly, it's hard to argue with the video, but there is a caveat. There were many different kinds of Shermans, and the video only tests one of them. I thought I'd take a look at some trials performed by the Western Allies in Europe to see if they arrived at the same results.

British Primer Minister in the USSR

Winston Churchill, the British Prime Minister, visited Moscow in August of 1942. However, a Churchill arrived a month prior to that in another Soviet city, Archangelsk, with the PQ-17 caravan, and not just one. These, of course, were Churchill II and III infantry tanks. 301 tanks of this type were sent to the USSR, 253 of which arrived at their destination. Despite a rather small volume of shipments, the prime minister's namesake played an important role on the battlefields of the Great Patriotic War. Suffice it to say that these tanks, along with the KV-1S, were the primary heavy tanks of the Red Army during the Battle for Prokhorovka.

AK Accessories

The accuracy of an automatic weapon is important, and many experiments were run on the AK platform to figure out if it can be increased. A number of experimental muzzle devices were built for this purpose. _tezka provided this picture.

Nashorn Notes

"On firing positions for 88 mm SPGs (Nashorn, formerly Hornisse)
  1. During use of self propelled anti-tank guns, it is important to perform thorough reconnaissance (preferably on foot). Frequently, the neighbouring section of the front turns out to have more favourable conditions for firing and ambush positions. In that case, the commander of the anti-tank unit must apply them in the neighbouring sector, and not in his own. The specifics of this weapon require certain flexibility in its use. The only important thing is that it must function as effectively as possible.

DP in Combat

"To the commander of the 74th Rifle Corps

The use of the DP in modern battle
  1. In all types of combat, the DP light machinegun was and remains the main automatic weapon of the infantry squad.
    1. During penetration of enemy defenses, the crew, following in the squad formation, can quickly prepare for battle and conceal itself and then open massed fire against enemy strongholds that are preventing the squad from advancing.
    2. When blocking and liquidating bunkers and dugouts, the effective long range fire and rapid maneuver of the DP crew on the battlefield makes it the most effective weapon of an infantry squad.
    3. When reinforcing a captured line, as well as when deflecting enemy counterattacks, the DP crew can quickly prepare for battle and open sufficiently powerful fire, while heavy machineguns and other types of heavy infantry weapons are not available at the squad level.
    4. When pursuing the enemy, the DP crew is always prepared to open fire.
    5. In the defense, the sufficient range and the ability to stealthily change positions ensures the successful deflection of the enemy.
    6. When clearing enemy trenches during an offensive and during reconnaissance, the submachinegun is more effective.

Overweight Showpiece

Dead ends in tank building are not uncommon. They are often caused by militaries who cannot make up their mind about requirements for prospective armoured vehicles. The end result is a tank that has many of its parameters far out of the initially planned range. The Americans were no exception to this rule. One such vehicle, the Medium Tank M7, was even standardized. This tank was designed as a light tank, but accepted into service as a medium.

Don't Leave Well Enough Alone

On March 25th, 1936, the French cavalry accepted the Automitrailleuse de Combat modèle 1935 S into service. More commonly known as the SOMUA S 35, this tank was officially classified as an armoured car, but turned out to be one of the best French tanks of the interbellum period. It combined sufficiently thick armour, powerful armament, and decent mobility. Despite its respectable characteristics, work to replace the tank began in the late 1930s. This decision appears rather logical, as the development of armoured vehicles was moving very quickly. This article will discuss the history of the SOMUA S 40, the prospective replacement for the S 35 that nearly made it into production. Alternatives to this tank designed during German occupation will also be mentioned.

Sturmgewehr Intel

Some of you may have wondered when the Soviets noticed that the Sturmgewehr has joined the arsenal of German infantry. Wonder no more! Via kris-reid:


"To the People's Commissar of Defense, Marshal of the Soviet Union, comrade I.V. Stalin:

Since the Spring of this year, forces of the Kalinin, and then Volkhov and Leningrad Fronts have captured, among other weapons, several specimens of new German automatic 7.92 mm carbines, which are a new type of infantry weapon that has not been previously used by the Germans in large amounts until recently."
