    Also if we go back to the AI driver I think that first it will be implemented as working just in a "follow the leader" mode and only for the auxiliary vehicles as Looser pointed out (feeding ammo and other supplies seems to be the first candidate for an automated task). It will take a very long time for the AI to reliably solve many tasks which are quite simple for the humans - such as "Can I go through that green fence?" or "Will that ancient wall made of laid stones stop my tank?"

    OK, this belongs here I guess.

    I think that also in 2017 MiG-31 shot down another with a BVR missile.

    Do all original T-90 (with cast turret) have these old single pin tracks?

    Allegedly a Russian Su-35S accidentally shot down a Su-30SM today near Tver - by cannon. Both Su-30SM airmen ejected.

    I bet that in this decade there is no self-driving MBT except for maybe very special cases used in extremely risky situations (optionally manned vehicle used without the crew in urban combat could be a possibility). But even in such cases I think that they will be rather driven by a driver sitting outside the vehicle and not by AI. Before the AI is mastered in the air I seriously can't see any chance of success on the ground. The air is waaaaay easier to solve and we are not yet in the point where AI is able of more than very simple tasks in a completely free environment.

    Laser scanners are a common thing in autonomous driving, usually combined with cameras and radars (because each sensor catches something in certain conditions better than the other) but that won't help you not getting stuck in the first deep mud or snow you encounter. It can work on hard surface but we are still very very far away from having AI capable of getting through tough terrain. For example today there are many occassions where the crew has to come out and test the terrain before the driver goes in and even then he has to perfectly know how he wants to cross such obstacle so that he won't get stuck. This is a task I can't imagine how AI could do. How can it make its own plan to cross such piece of terrain without having this simple possiblity of the human to go out with a piece of wood and test how deep it is in which place and set its own plan where to go, where to push full throtle and where to go pretty slowly instead? Roads and hard surface are likely doable in the future but mud, water, snow? Another thing - the bushes and little trees and all that green stuff. How can the AI judge what it can simply ignore and go through and what is dangerous to hit? That's something the autonous driving technology also never needed to solve. Plus a hugely important thing - the other crew members must have absolute confidence in the driver. IMHO that won't come anytime soon.

    How would the commander give the tank the orders where to go without actually somewhat driving himself? How would it go through rough terrain which can not be judged by the video image (depth of water or mud for example)? I am quite skeptical about this sort of automatic driver to be honest. It's totally different than driving on the road according to the traffic signs and firmly given rules (even that is a mess at the moment, for example there are situations which don't have and can't have any correct solution by automatic systems - it's just that polititians don't like to hear that).

    Is there a thread for Iranian hardware? If so I overlooked it and appologize.
  10. Beer
    This is interesting. Did Iran use reverse engineered Turms-T for its Karrar tank?

    All three contenders for the Czech IFV tender shall have been displayed during the NATO days in Ostrava (this year's strange edition without spectatos). In the end CV90 didn't appear at all, Lynx was only on static display and only ASCOD was shown driving. Due to the fact that there were no spectators it's also difficult to find any photos or videos. This is finally the ASCOD with the right MT30-MK2 turret. Source: https://www.czdefence.cz/clanek/dny-nato-a-prezentace-uchazecu-na-nova-bvp-pro-acr ASCOD driving @4:01:32 (mostly slowly cruising though), I have some troubles with the video (randomly slowing down) and I don't know if it's a problem of the original stream or mine. No such troubles with other videos.

    I don't think that three Bradley are worth of any reaction. It's a show.

    Bradleys in Hasaka. Meanwhile Apaches joined the Mad Max series.

    Anyone could hear any 6TD-2 equipped tank side by side with other tanks? I mean the ejectors work but usually they are also very loud.

    Czech MOD signed a tender for large mainteanance and small modernisation of all T-72M4CZ tanks (27 standard tanks, 3 command tanks and 3 bridge layers). Aside of general rebuild to prolong the service life (and in fact to bring part of the non-serviceable vehicles back to life) there is a plan to modernize the FCS and communication equipment. https://www.czdefence.cz/clanek/nakup-anebo-modernizace-armada-resi-tanky-t-72m4cz

    Aero L-39NG has now EMAR 21 and EMACC international military certification (valid for all NATO and EU countries). https://www.dnoviny.cz/letecka-doprava/aero-vodochody-letoun-l-39ng-ziskal-typovy-certifikat Also the first PP16 L-159 was delivered to the Czech airforce. PP16 means a large mainteanance action after 16 years of service prolonging the service life by another 8 years. Part of that is small modernisation of instruments (better NVG compatibility, some modernized displays and added Integrated Stand-by Instrument System. All 16 single seaters will go through this procedure. The 8 twin-seaters (5 T1+ and 3 T2) are newer and don't need it yet. https://www.armadninoviny.cz/aero-vodochody-dodalo-armade-prvni-l-159-po-predepsanych-pracich-pp16.html

    There may be many drawings circulating and non-insiders have very little idea which version of a drawing is the recent and correct one. Sometimes even insiders don't know what they actually produce (real life experience from different field of products). Measurement on the real thing is clear on the other hand.
  18. Beer
    Sorry to jump into the discussion but this is outright silly. It's based on the believe that the schematics are perfectly correct in details they are not supposed to represent accurately. Anyway the general rule is that the only valid value from any drawing is the one with an explicit dimension - and that applies twice as much for any drawing from the old times when 2D was not yet simply generated from 3D by software.

    Of course, I was only commenting the elevation angle alone.
  20. Beer
    Yes, this is one of the GDELS favourite arguments in our IFV tender however they somehow forgot that the old BMP-2 to be replaced have 75° gun elevation and that therefore this argument sounds a bit funny.
  21. Beer
    It looks like the thin side turret panel was not penetrated. Most of the damage looks like a result of fire from the external fuel tanks. Am I right?

    A police ammo dump exploded near Bílina, northern Bohemia (allegedly used for storing various old ordonance found around the country). Article includes video of one relatively small boom (out of 3-4 ones). https://www.novinky.cz/krimi/clanek/na-teplicku-hori-sklad-policejni-munice-ozyvaji-se-vybuchy-40336410
