He has a lot of videos like that. One of them is him in a room full of cadets. He goes through all the drone innovations that the Russian and Ukrainians have made in the past year and passes around a (disarmed) working €321 drone.
Then he points out that Austria still has the same expensive drone they had years ago and tells the cadets they should be a bit stressed about that.
I’ve found that Colonel Maruks Reisner provides some of the best information available on the war.
He doesn’t update frequently but all his analysis are sober, detailed, and realistic. He states his pro-Western, pro-NATO, pro-Ukrainian bias clearly.
If I could sum up the general trend of his presentation it’s, “The status quo favors Russia. If we don’t get our heads out of our asses and step up Russia will win.”
I’m not aware of any major predictions he’s gotten wrong. As near as I can tell, he’s very focused on ex-post analysis.
Ukraine is still in the fight but it’s clearly loosing. Ukraine is still rich in subjective resources like “spirit” and “determination”. When it comes to hard metrics the picture is pretty bleak; casualties, ground gained, artillery production, depth of reserves…
The “we” wasn’t a quote by Colonel Reisener. I did put it in quotation marks but I thought it would be clear from the vocabulary that I was paraphrasing him. I’m sure you already know that Austria is constitutionally obligated to remain neutral. While Austria is barred from providing military assistance it has participated in sanctions and provided humanitarian assistance. That’s earned Austria a spot on Russia’s official Unfriendly Countries List https://en.wikipedia.org/wiki/Unfriendly_countries_list
I try to keep a more complete set of facts in mind when assessing the reliability of sources.
