I guess that too easy mobility kill doesn't help the crew survivability either...

Don't know when this was filmed (the video) but judging by the Chinese having facemasks it must be from 2020. Two nuclear powers figting 5000 BC style...

Pitty they didn't restore the Czechoslovak /Laos tanks to the WW2 state but I guess 99% of the audience would not find the difference anyway. Seeing sooo many T-34 at once in 2020 must be something. For me it would be probably bigger thing that to watch the T-14...
T-34 destroying the street...

Any information about how is Derivatsiya supposed work in the real world? It doesn't have any radar continuously monitoring it's surroundings. Is the top optical head constantly rotating scanning around? If not why does it have two of them? Does it need to work with additional surveillance radar?

FWIW, the Rolls Royce Wankel Diesel was actually built.
There were, as I mentioned, a few others.
Yes, I know. Though the Curtiss Wright one was not a real diesel. It burned diesel but it used spark ignition.
Anyway, You are right, this last RR prototype looks to be really functional one (though the actual fuel consumption, reliability and durability is questionable as it looks like no testing was ever done or at least there is no info about it available). I learned that the development in Rolls Royce was stopped when the company went bankrupt and was briefly restarted when it was nationalized but soon again stopped. One can only guess that there was a reason why they didn't continue.

A wankel engine for a tank is attractive on paper; like I said, three companies have tried it (although none made it work). Turbines have improved a lot since the AGT-1500 and GTD-1250 series, but I think a turbocharged wankel would still enjoy a bit of an edge in specific fuel consumption.
I have just discovered this hillarious thread thanks to Alex bringing it back to live after four years. The discussion about Wankels is particularly interesting though. AFAIK not even those experimental Wankel diesels were able to produce reasonably more power than they consumed. Aside of other issues common to all Wankels the diesel one has another much bigger ones related to the chamber shape (it was partially mentioned here already). The first is that from its principle it can not achieve high enough compression ratio to work at all, i.e. it needs to be fed by a compressed air to even run. So you need either sort of two-stage Wankel where one works as a compressor or you need an external supercharger. The other is that the chamber shape is absolutely wrong for diesel (there is no solution for proper injectior position and therefore also the mixture formation) and you can't do anything about it. Both things combined mean that the efficiency of such engine is abysmal and at least in some of the experiemental engines it was in negative values. And now all the other issues of the Wankel design on top of that...

Yesterday on M4. The BTR-82A was later seen towed by Turkish truck, maybe the engine was damaged by splinters.

Something hit the airbase but I don't think it's a BM due to the visible smoke trail. Maybe failed Patriot missile hitting ground?
And a Houthi monster technical

The linked article contains fascinating information, photos and schematics for the 5N76 Terra 3 Sary Shagan laser.

I am afraid we will need a special thread for the Indian-Chinese quagmire. Yesterday 20 Indian soldiers died in a fight with the Chinese. Some sources say another 45 were captured by the Chinese and 135 wounded. No reports about Chinese casualties except Indian claim about 43 dead and seriously wounded. Some say these massive casualties were result of a hand to hand brawl and falls from high cliff, I don't know.

An USAF F-15C from RAF Lakenheath crashed into the North sea. The pilot is missing at the moment.

Looks like new CIA drone strike with the R9X "Ninja" Hellfire. And I think htat it's just one missile which went through the moving car.

There was a ridiculous incident on Czech-Polish border. In short - Polish army guarding the borders closed due to the coronavirus measures crossed a creek into Czech Republic and set a checkpoint at a chapel some 30 meters inside our country. They blocked the entry of several people who tried to get there (for example a man responsible for chapel's reconstruction). They spent there several days before they finally left.
Linking English article, not the original one so that you can easily understand. Anyway I think that the article makes it a bit more dramatic than it was. People here mostly don't even know about it or make jokes about it.
Original photogallery of the Polish checkpoint: https://moravskoslezsky.denik.cz/galerie/pelhrimovska-kaple.html?back=1956917446-8118-57
For me the most funny thing is Poles preventing Czechs from entering a chapel instead of forcing them to enter (Poles are one of the most riligious nations in Europe while Czechs are one of the most atheist nation in the whole world)

2-3 bottles brews up a moving vehicle, 1 bottle if it was stopped by something like a grenade to the tracks or a mine since you can properly aim at a weak spot. They were no wonder weapon, but they worked well enough.
Don't know where to put it. Here is someone having a great aim with Molotov cocktail hitting an M-113 from afar, yesterday in Lebanon.

As far as i know, the russians are already working on guided 57mm ammo but i think that its going to be compatible with the larger case and used for AA, which makes a lot of sense.
I think that the guided ammo is used by Derivatsiya-PVO. I don't know if it's interchangeable with the T-15 gun ammo.

More in the tweet thread.
And in other news, TSK combat engineers in Tripoli.

It is still a headache, but the values from Mr. Alex Luck are not supported by the linked official report from the German MoD. It seems that he didn't actually read it, but only glanced over it.
The Puma's readiness is not mentioned. Instead it is stated that the availability/readiness of new weapon systems is ranging between 30% and 93%:
"Beispiele für neue Systememit einer im Verlauf hohen Schwankungsbreite der materiellen Einsatzbereitschaft zwischen 30% bis 93% - sind u.a. SPz PUMA, A400M, H 145M LUH SOF, Geschützte Transportfahrzeuge (GTF) Zuladungsklasse (ZLK) 15t und NH 90."
The readiness of old systems meanwhile is really not different, ranging between 26% and 89% depending on the exact weapon system:
"Beispiele für alte Systememit einer im Verlauf hohen Schwankungsbreite der materiellen Einsatzbereitschaft zwischen 26% bis 89% sind u.a. TORNADO, CH-53, P-3C ORION, Betriebsstofftransporter."
Thus it appears that the "troubled" new weapon systems are actually a bit more reliable than their worn-out counterparts. This becomes even more clear when looking at average readiness rates - on average the eleven new weapon systems have a readiness rate of above 70%, while the 26 old weapon systems have a readiness rate of 67%.
However the exact situation for the Puma certainly isn't great. The Puma IFV belongs to the four new weapon systems with the lowest availability - for all of these systems special programs have been started to improve availability. A problem is that when the original contract was signed, spare parts and tools required for maintaining the Puma were reduced to a minimum in order to cut costs. As a result the spare parts order for the Puma IFVs meant for the VTJF 2023 also included lots of tools required to maintain/repair the vehicle that are lacking at many German Army sites in the relevant numbers.
The stated 80% readiness of the MRAP is also not mentioned in the document. The figure 80% is only mentioned twice: first in a passage mentioning that the availability of the helicopters used for flight training is 80%, and that Germany wants to purchase more market-available - so called "80% solutions", i.e. solutions that do not meet all requirements, but are already available and don't require a costly and risky development - in the future.
Edit: the last time the Puma's readiness rate was openly mentioned, it was 39% and according to reports, the situation is getting "better". A big issue according to the new official report is the low quality of "fresh from the factory" weapon systems, specifically for the Puma and the F125 frigates, which often results on systems being rejected by the Bundeswehr and then being fixed (a few times) before officially accepted.
I went through the report quickly myself and I admit I haven't found the 30% value explicitely stated as well, however Puma is clearly mentioned several times in the report as "negativbauspiel".

Looks like Puma is still a headache for Bundeswehr.
