This are the requirements written in 1977/1978 of the Dutch army when they needed a new tank which became the Leopard 2.
a: with direct fire kinectic or chemical energy ammunition of enemy tanks or anti-tank weaponsystems to a distance of 2000 mtr (only for the frontal armour)
b: direct fire armour piercing projectiles with a caliber  from 20mm to 30mm to a distance of 100mtr (all around)
c;  the effects of shrapnel from enemy 152mm HE exploding at 30mtr distance
d: enemy detection
e: fire and explosion after a hit
f: AP mines and the effects of AT mines as long as they don't explode under the hull
g: against the use of NBC weapons including the effects of an EMP
(in a other document about the nuclear protection, minimal 20KT at 1km 50% change tank and crew 1 hr employable)

And this is what the Germans told about the protection of the Dutch Leopard 2A4s

So I was on my end of year/ New Years trip in central Florida visiting family, when we spotted some MiG in my home town. My brother said it’s been there for 3 or so years. Unfortunately, I can’t seem to make spoilers on the site from my phone, so I’m only gonna post some of the photos to save on scrolling: 
 

 

 

 

 

 
My brother says it’s a MiG-21 trainer, but I’m curious how the hell it ended up in Florida, and where it came from. Any of these markings help identify her? 

Shows guts of Mi-24P, pretty detailed.

A render of potential components for a K1E2 upgrade. 
 
Components include the NBC protection (utilizing overpressure) which the K1 variants up until this point have lacked, air conditioning and heating, an 8Kw APU, and an additional battery bank. These additions are fitted to the space currently taken on the K1E1 by the bustle storage boxes along with extending the rear hull side storage to hold the APU, heater, and battery bank.

An updated design of the Hyundai Rotem Next Generation Main battle Tank was showcased recently at the autumn conference of the Korean Institute of Military Science and Technology. Don't have much other in the way of info.

AAI RDF-LT on display at Nokesville, Virginia, in September 2021:
 
 
Blast from the past: RDF-LT with unmanned turret and two quad Stinger launchers, at AUSA 1984.
 

 

A rare picture: an overhead shot of the M1 Thumper, used to test the XM291 ATAC gun (sometimes referred to as LW120) in conjunction with the XM91 cassette autoloader.
 

 
The Thumper, which was built out of a M1A1 at Anniston Depot, used a 120mm XM291 in three different barrel lengths, one 265in/6.75m long (the standard, "long tube" XM291), a second one cut the same length as the M256 ("short tube", 5.3m) and a third, intermediary one ("medium tube") that stands somewhere between 6.75m and 5.3m.

On-the-move test fires done at speeds of 10, 15 and 20mph showed that the target impact dispersion (TID) was bigger (read: lower accuracy) with the "long tube" XM291 compared to the "short tube" or EVEN the M256, which was problematic. To support the increased barrel length, Benét Labs also had to create a 415lbs and 22in-long extension for the gun cradle...which was later reused in the proposed installation of a XM360E1 inside the notional M1A3...and, quite likely, inside the M1 AbramsX demonstrator showcased at AUSA 2022.
 
 
 
The 1988 M1 Thumper was only fitted with the 120mm ATAC gun, but the XM291 installed on the 1993 M1 CATTB, on the other hand, went on to trial a 120mm and a 140mm barrel. At one point, the ATAC prototype pool was noted to have successfully fired 1,300 rounds, 150 of which were of the 140mm variety. The latter (at least the KE part) was even judged capable of defeating the armor of what was tentatively described as the FST-3 (Future Soviet Tank 3, essentially a Obj.477/477A); there are no known numbers for the 140mm XM964's performance, but the 140mm ATAC itself was expected to produce a great maximum of 25MJ of muzzle energy. The ammunition for the ATAC was developed by Valentec International and Hercules.
 
 
 
While the Thumper was originally meant to trial the 120mm ATAC, some of the official literature indicates it may have also undergone the 120-to-140mm tube conversion and done static test firings at Aberdeen Proving Grounds, where it showed precision equal to a M1A1 but "with greater penetration".
 

>> Source document for the two above scans <<
 
Also, a common mistake (one I've also been guilty of, mea culpa) I often see around in forums and milblogs is that the Thumper is a derivative of the CATTB, which is false, as the Thumper (AKA the ATAC Demonstration System) predates the CATTB Phase I by at least five years.
 
M1 CATTB Phase I (using a M1 hull as basis), in 93/94, about to be shipped to Aberdeen Proving Grounds for testing:
 

 
Picture of the CATTB Phase II (ATTD?) hull under construction, completed in 1994. Note the closed back with no exhaust grille, the absence of apertures for torsion bars (replaced by a hydro-pneumatic suspension system) and the smaller engine compartment designed to receive a Cummins XAV-1000 AIPS instead of a Honeywell AGT-1500. The freed-up volume between the XAV and the turret basket was reclaimed to accept two vertically-stacked non-ready cassettes housing a total of 22 rounds (either single-piece 120mm or two-piece 140mm), which would have given the CATTB Phase II a maximum loadout of 39 rounds (either 120mm or 140mm), just five less than a M1A2. The huge tradeoff, of course, was that all this made the CATTB massively overweight.
 

 
Apparently, at least one of the two CATTB testbeds is currently sitting at the Sierra Army Depot in Herlong, California, but one has to wonder if it's not a case of mistaken identity; the Thumper was, after all, spotted in 2010/09/30, in Ohio, as it was being relocated by train to parts unknown. Here's to hoping any of these big bois shall make their way to a museum one day, as did the TTB, the Crusader and many others before them.

Since Brazil's 8x8 program is wrapping up I thought I would talk about the VBC-CC which will involve Japan that has little to no coverage outside of Brazil. There is basically nothing in terms of Japanese or English sources.
So back in 2019 the head commander of the Brazilian army traveled to Japan the look at some Japanese weapons systems, but primarily the Type 10 and Type 16.
https://web.archive.org/web/20190821132735/https://www.defesanet.com.br/br_jp/noticia/33633/Comandante-do-Exercito-Brasileiro-em-viagem-oficial-ao-Japao-visita-escola-que-prepara-Forcas-Blindadas-Japonesas/

 
The Type 16 wasn't possible for VBCAC-MSR as it was conducted before Japan's relaxation of weapons exports. However the succeeding MBT program is taking place in 2023 and so the Commander recommended these specifications for the future MBT program
https://www.janes.com/defence-news/news-detail/brazilian-army-releases-requirements-for-its-new-mbt-project
The requirements for the program basically eliminates every MBT besides the Type 10, one special vehicle and arguably the T-84-120, but that doesn't feature the required low recoil gun.
But then the requirements go further and even eliminate the Type 10 and T-84 with a 4 man crew requirement. This leaves only 1 maybe 2 options.

Just last year a delegation from the ATLA went to Brazil to evaluate Brazilian vehicles and discuss technology transfers.
"'As part of our national defense strategy, we are challenged to seek solutions. In this sense, the Japanese Army is very open to interaction and technology transfer', evaluated General Ribeiro."
The biggest thing to note is that they evaluated the Osorio during that time which is essentially the only MBT that qualifies under the released specifications.
 
The current options seem to be a modified Type 10 to accommodate 4 crew members, new MBT co-developed by both countries, or an updated Osorio using Japanese electronics, JSW cannon and, Japanese armor from the Type 10.
 
I see the upgraded Osorio as the most likely candidate, but it will be interesting to see where this program goes now that it will start to pick up some steam.

Dunno if it's ever been posted here, but I'll leave these as is - PDFs from Benét Labs, ARDEC and Tank Main Armaments (Picatinny Arsenal) on the ATAC gun project.
