    Contemporary Western Tank Rumble!

    I've been wondering about the protection difference between the Swedish version and the German version. What I found very odd is the table on the last slide I originally posted, which list the Leopard 2 Improved with Vorsatzmodule of the generation "D-2" and internal armor of the generation "B". I think this might be a reference to which prototype was send to Sweden for tests. The original Leopard 2 Improved prototype was the Komponentenversuchsträger (Leopard 2 KVT; "component test bed"), which was based on the chassis number 20825 (the 825th tank made by Maschinenbau Kiel). Based on this number, it appears that the hull (and turret) were made as part of the 6th Leopard 2 batch (the second batch of 2A4 tanks) made between January of 1988 and May of 1989. The previous batch (batch number 5, first batch of Leopard 2A4 tanks) was produced between December of 1985 and March of 1987, while the last batch of Leopard 2A3 tanks ended with the chassis number 20644 for MaK. Given that 45% of all German Leopard 2s were made by MaK and the 5th batch consisted of 370 tanks; therefore I assume that the 5th batch ended with the chassis number 20810 or 20811. The first 96 tanks of the sixth batch were made with the old armor, therefore the chassis number 20825 would fall into that category. The later Leopard 2 Improved prototypes (Truppenversuchsmuster Maximum and Truppenversuchsmuster Minimum, "troops trial model maximum/minimum") were based on the chassis numbers 11156 (TVM max) and 11157, which were made by Krauss-Maffei and belonged to the 8th batch (the last batch of tanks for the German Army) made between January of 1991 and March of 1992. This would mean that original KVT (later renamed IVT) used 1st generation composite armor (also confirming that the "B" in the table stands for the original composite armor), while the TVM tanks had 3rd generation armor (believed to be "D-1", "D-2" or "D-3" in the table). The actual Leopard 2A5 and Leopard 2A6 tanks were made using hulls from the 6th, 7th and 8th batches - so all German tanks with the second and the third generation of composite armor + 22 tanks with the original hull armor package. If the hull armor wasn't altered (although I assume it was), this would mean that there would be some tanks with worse/better hull armor than the others... The turrets were all taken from the 1st batch, so they probably replaced the armor inserts and upgraded them to "C" or "D-1/2/3" level. According to the book by Scheibert, the armor modules in the turret were replaced. According to one issue of the Waffen-Arsenal magazine ("Leopard 2 A5 - Euro-Leopard 2" by Michael Scheibert), the Leopard 2 tested in Sweden was either a KVT/TVM mix or they tested both variants (not written clear enough for me to understand what was the case). In theory this might mean, that the higher level of protection of the Swedish variant is just the result of using "C" or "D-1/2/3" level armor inserts with the same Vorsatzmodul. Yes, that's true. However I've never seen a cast turret with composite armor in the gun mask and Soviet gun masks tended to be thinner. Also the composite filler of the turret always ends a few centimetres away from the gun mount.

    http://www.wtsp.com/article/news/atf-investigating-after-congressional-candidate-cut-apart-ar-15/291-526898428 Looks like that video finally got the attention of the ATF. VIRGINIA-BEACH ATF investigating after congressional candidate cut apart AR-15 Karen Mallard of Virginia Beach posted a video on social media that shows her sawing an AR-15 rifle into pieces. Author: Staff Published: 6:21 PM EST March 8, 2018 Updated: 6:21 PM EST March 8, 2018 VIRGINIA BEACH, Va. (WVEC) -- The Federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is investigating congressional candidate Karen Mallard after she posted a video on Facebook that shows her cutting apart an AR-15 rifle. The school teacher and Democrat is running for Virginia's 2nd Congressional District, hoping to oust Republican Congressman Scott Taylor. In the video, as Mallard introduces herself, she says, "I grew up in Wise County, surrounded by guns. Our family had guns my whole life. We use them for hunting, for protection, and recreation." She goes on to explain that she wasn't happy when her husband bought the AR-15 "a while back." Mallard adds that after the deadly shooting at Marjory Stoneman Douglas High School in Florida on February 14, and the renewed outcries for stricter gun control that followed, she and her husband agreed they didn't want the AR-15 in their home. The couple later decided they didn't want it it anyone else's house, either. "So, today, we're going to destroy it," states Mallard before taking a handheld power saw to it. In a matter of hours, the video drew hundreds of thousands of views and thousands of comments. Many of those comments were negative. Some people accused Mallard of political grandstanding. Several others said Mallard broke federal law by taking a legal firearm and altering it, making it into an illegal one. Many of them referred to details contained within the Sawed-Off Shotgun and Sawed-Off Rifle Act which, in part, prohibits people (except for those permitted by the act) from having a rifle that has been "modified to an overall length of less than 26 inches." Virginia Firearms Statutes and Codes by 13News Now on Scribd Mallard said she followed legal procedure, writing in her Facebook post: And yes for all the NRA trolls out there, I finished the job according to regulation and turned it over to the police. Why are you more outraged about me taking a gun out of circulation than about our children being murdered in our schools? Master Police Officer Tonya Pierce, spokeswoman for the Virginia Beach Police Department, confirmed that the rifle was in the department's possession. Pierce told 13News Now the ATF was looking into the situation. Mallard concludes her video with the promise she will fight for comprehensive gun control and states: And to those students in Florida and across our country, keep standing up and speaking truth to power. These gun owners heard you, and we're gonna stand by you.

    It's interesting. Presentation (which contains this page) which available now on ontres.se is 110 pages long about 2-and-a-half years ago i've downloaded on my computer presentation which was 119 pages long. Apparently it's exactly the same as one available now online, except for some pages on tank protection https://cloud.mail.ru/public/FVLe/iUZw87trH (according to Chrome history file, which i've backed up in dec.2015 and still have now, this pdf was without a doubt downloaded from ontres.se https://i.imgur.com/ysAJQgr.png)

    So I had a bunch more links on RAVEN, these don't seem to have been posted, so I'm posting them. Dr Eric Kathe is a prolific guy: http://www.dtic.mil/dtic/tr/fulltext/u2/a435128.pdf <- this one is a 317 page thesis by Dr Kathe on RAVEN in relation to other recoilless concepts http://www.dtic.mil/get-tr-doc/pdf?AD=ADA398942 <- pdf download if you click on the link. Google cache link here:http://webcache.googleusercontent.com/search?q=cache:6eBVulAzScsJ:www.dtic.mil/get-tr-doc/pdf%3FAD%3DADA398942+&cd=5&hl=en&ct=clnk&gl=us It's another technical paper by Dr Kathe in the same vein as the above, but with fewer pages. https://ndiastorage.blob.core.usgovcloudapi.net/ndia/2015/armament/wedKathe.pdf < - powerpoint along the lines of what you posted a few years back, but with some other differences (I think) which analyzed alternatives https://ndiastorage.blob.core.usgovcloudapi.net/ndia/2015/armament/MondayKathe_Tutorial.pdf <- another powerpoint. With the monday/wednesday thing I think it wsa part of a larger seminar in 2015. you posted one of those originally (the Tuesday one) Some technical reports on RAVEN and the tech demonstrator http://www.dtic.mil/dtic/tr/fulltext/u2/a597442.pdf http://www.dtic.mil/dtic/tr/fulltext/u2/a591200.pdf http://www.dtic.mil/dtic/tr/fulltext/u2/a504316.pdf And another powerpoint: https://ndiastorage.blob.core.usgovcloudapi.net/ndia/2010/armament/WednesdayLandmarkAMikeBixler.pdf I'm also fascinated by RAVEN and it has many nifty implications regarding 'light weight without losing performance' as far as recoilless technologies go. One was for improving man portable firepower (mentioned in the first pdf Collimatrix posted in the original post.

    Yes, it was planned to give GLATGM for next generation tanks. But no details about missailes and no even codenames. Just info about work on cal.152mm GLATGM.
