I’d say this is false, even as I myself am a US Army veteran who spent a year in Iraq 2003-2004. Tanks are still useful, but aren’t as useful against non-conventional forces.
The pentagon has spent the past 4-5 years retooling for what they call “near peer” threats which is to say China in the Pacific and Russia in Europe. Tanks, and really good ones in specific, would be required to push back a Russian incursion into our allies.
