  • Speculation on my part:

    Patriot stocks may have been really reduced - by defending Israel during Netanyahu’s adventure against Iran (it could have been smarter to tell Netanyahu not to start).

    There is no reason to think that stocks of other weapons (e.g. air to ground missiles, glide bomb units for F-16) have suddenly gone really low. In fact, there is probably a f**kton of them.

    Consequently, I suspect that Trump and Putin have made a deal they failed to disclose: Putin promised to refrain from helping Iran (it was an easy promise, he was really low on supplies). Trump promised in return to refrain from helping Ukraine, which he could have easily helped. At best, he got conned, at worst he got to do what he already wanted.

    I would advise journalists to ask around: “has the US DoD been ordered to alter criteria for determining what is sufficient supply?” If yes, we’re looking at an excuse. If no, we’re looking at inability.

    Both are bad, but inability can be corrected with honest admission and action, Ukraine has a bit of money from other allies to actually buy some US weapons, although they are rushing to make more domestically.

    If it’s not inability but an undercarpet deal, then corrections are bit harder to achieve.









  • Clever and economical, and 100% high value military targets. I wish the guys who pulled this off, all the luck they can have. :)

    It is possible that Russia’s selection of AWACS planes (about 10 left) decreased even more.

    The “sheds” were more like wooden boxes. They had a fake roof, the upper layer of which a mechanism could remove. Between the roof beams - “nests” for drones. This cargo was given for transport to ordinary truck companies. There’s even a video where cops have detained a trucker while drones are taking off from his truck and heading towards Belaya airfield, ordinarily unreachable to Ukrainian drones since it’s 4000 km away. I’m afraid the trucker will be facing some hard times. I hope they understand he was deceived, though, and eventually let him go.

    Nice to know. :)

    Reading tip: a comment from a reader John Beech (an old radio amateur) at the bottom is probably of greater practical value: he describes how he developed DIY cells to the point of running a 2 W radio.

    Another way to build DIY batteries is using the iron-air chemical combination. A decent collection of recipes can be found here, using filter cartridges of activated carbon as cathodes and rebar wrapped in steel wool as anodes:

    These cells convert iron into rust at an accelerated pace, producing power while doing that. However, they have really low cell voltages, so you have to wire many cells in series or use a really efficient voltage converter. Aluminum gives high cell voltages, but on the downside, produces annoying waste chemicals.


  • All useful information.

    I would add some notes. They are somewhat haphazard, I apologize, it’s 3 at night here. :)

    In a protest setting, where police might use non-lethal weapons, protective equipment can save the day repeatedly. It also protects well enough against thugs with clubs.

    But if lethal weapons are used, even the best armor often fails and everyone is too fragile, despite having armor. Generally, in such conditions, other factors (awareness, coordination, range) determine outcomes.

    Generally, quite soon after armor has proven useful, an age-old pattern emerges: competing factions erect barricades. At that point, much depends on what the population thought before that - whether the population is willing to support and supply protesters, or maybe even sabotage attempts to suppress them. If the population is “meh, it’s not my fight”, for a protester, that is bad news.

    Needless to say, it’s best if peaceful mass protest can occur before this stage, and show great numbers. Srdja Popovic (whose colleagues helped remove Milosevic in Serbia, but it took them ages and required external help) makes several good points in Blueprint for Revolution. If a protest has no risk of violence, grannies and people with kids show up. Critical mass is shown and vital communication lines are established this way, police are aware that they will lose popularity fast if they initiate violence. Various factions will try to propose leaders, leaders will try to propose strategies and tactics. However, mass protest could lose momentum or fragment into non-cooperating factions. One way to protect a movement against loss of momentum is to build an organization that gathers resources and funnels them into the struggle, and to have achievable waypoints before a distant final goal. This way lies politics.

    Another way out of mass protest is for protesters to attempt subverting power structures at a rapid pace - typically after gaining confidence of having overwhelming numbers, something which the phase of peaceful mass protest seeks to demonstrate. This way lies revolution, with a far greater risk of violence. It’s best not to go there without really having overwhelming numbers, and a clear message of how chaos will be short in duration (most populations in a tumultous situation desperately look for a message of how chaos will be over, and it’s best if a rotten government ain’t the only place offering one).
