Interesting comments from the US military, worth a watch...
That former US military guy is literally the person who has spoken the most inaccuracies about the ongoing war, which were later exposed as lies. He uses his status as a former U.S. military member to make people believe that he's special or has privileged information and to say the most absurd things about Ukraine in order to gain likes and views. Additionally, he is a frequent guest on pro-Russian programs, including Russian state TV.
Some of his posts get community-corrected despite the fact that his fans try really hard to downvote them.
For over a year, he has been saying stuff like "the war is going to end in the next few weeks, and Ukraine is going to lose really bad".
