This is another T-Rex talk about the big lessons from Ukraine. We already had an episode

about the small lessons of Ukraine. I think it was a couple months ago. It was a few weeks

into the war and we were looking at just a lot of footage, handheld camera footage,

live streaming footage directly from kind of the front lines of that invasion. And there were a lot

there were even incidents where there were multiple camera angles so you could really get a

better sense of what was working and what was not working.

And I bought a couple of different items based on some of these lessons,

including concertina wire.

Quick, quick note, don't buy concertina wire from Amazon.

You get stuff that is simultaneously too flimsy to be useful and too thick to be

sharp. And there's no telling whether it comes clipped, which definitely need clipped concertina wire.

So I'm currently in the market for a new concertina wire guy. What about big lessons? I think

obvious and people really need to learn from. And I'm not talking about the biggest lessons. I'm not

talking about morality and just war theory. Those are very important, but David Botkin is a much

better commentator on just warfare, has done a lot more research, has a lot bigger thoughts on it.

So I'm mostly going to be
