It’s time to check up on the blog “Below the Turret Ring” to see what they have been up to. Since last time we checked, they have posted two lengthy pieces, one on the armor configuration of the early model M1 Abrams, and a follow-up to their post from last year on Leopard II tanks in Syria. Click on the headlines in the excerpts below to go to the full version.
On the TankNet forums, a user with the nickname “whelm” has posted drawings from a formerly classified document on the earliest iteration of the US M1 Abrams main battle tank (MBT). He got this document from Vollketten, a user with accounts at the Sturgeon’s House forum, the WoT forum and other places. It details the armor layout of the tank, showing were the Burlington composite armor is located and how it is specifically implemented on different areas.
Burlington special armor, also known as Chobham armor, is a type of composite armor developed in the United Kingdom by the FVRDE from the late 1960s onwards. It consists of a number of sandwich plates – also called biscuits – which are mounted in a spaced configuration. It is understood that these sandwich plates work as a type of non-explosive reactive armor (NERA), by using an elastic interlayer located between two metal plates (usually steel or alumininum). On impact the rubber will compress to the point of maximum compression, until expanding again and bouncing back. This will move more material into the path of penetration and also shatter thin and fragile projectiles, such as the shaped charge jets created by high-explosive anti-tank (HEAT) warheads commonly used on anti-tank guided missiles (ATGMs) and rocket-propelled grenades (RPGs). Essentially NERA works like explosive reactive armor, but with a lot less plate movment, as it only reuses the energy from the impacting projectile, instead of using an external energy source (such as the detonation of an explosive layer) to move the metal plates.
Yesterday a new video was released by ISIS terrorists showing a bunch of destroyed main battle tanks (MBTs) and armored personnel carriers (APCs) near the Syrian city of Al-Bab. This video however has proven something, that I understimated a certain weapon. Not anti-tank guided missiles (ATGMs), not improvised explosive devices (IEDs). A much older weapon: propaganda. The same weapon that turned the Tiger heavy tank – a rather mediocre design of it’s time – to a supposed super tank, that still is being worshipped by some individuals today. However the propaganda worked, invoking a Tiger-phobia on the side of the allies.
Now, what exaclty has happened? A new video showing the exact same area that the first few videos were showing. The destroyed or damaged tanks are probably all identical to the tanks already shown in earlier videos, that have been covered by numerous news articles and blogs. Still some people start writing articles in a sort of kneejerk reaction, claiming that these are newly defeated tanks and that the Turkish Army is just poorly trained or the Leopard 2 is a poorly designed tank, incapable of competing on the same level as the tanks of other countries (even though this is not tank-vs-tank warfare…). This again leads to people to come and reply or spread the articles, which are pushing for their own agenda. “The T-90 is so much better, only one was penetrated!”, “All people who think the Leopard 2 is a good are Nazi-tank fanboys” and “The Abrams/Challenger 2/T-84 is an inpenetratable super tank”. People love to ignore the fact that the Turkish Leopard 2A4 is fitted with out-dated armor, possibly still the first generation of armor technology introduced with the original Leopard 2 in 1979. The fact that the Turkish Army was purged after the failed coup attempt – in which most tank units were equipped with Leopard 2A4 tanks – is intentionally ignored.
