To be clear, they are saying Russia is furious with their military:
"Russian milbloggers have said their army is “at war with our own stupidity and sloppiness”, after reports emerged that as many as 100 of Moscow’s troops were killed when a Ukrainian strike struck a gathering of soldiers waiting for their commander to give a speech. "
HIMAR
Probably a fun coincidence, but doesn't himar mean donkey in Arabic?
https://en.wiktionary.org/wiki/himar
Yes, but HIMAR is pronounced like "high-mar". So they don't sound the same. And they only look the same if you choose to write ح as "h" instead of "7" or some other letter that conveys that sound accurately.
I hope the commander was not killed. We need him to do this again, and again, and again! Слава Україні!
