You've dealt with these before in your tank?
Many times. I frequently assault the russians, it was a hobby of mine long before the ukrainians made it popular
But i'm sure you must have similar tank experience to throw your opinion out there right? Right? Hellooooo?
This is not a complicated thing
These kinds of devices have been used plenty since tanks first came out. In ww2 you saw them in a sort of 'caltrop' design and there's been many variations, usually based on what's available and affordable for material and the tactic is always similar.
The americans use 'em. The Israilis use them and used them in war against (gasp!) tanks! Most modern armies have a version, there's many shapes and materials. Arguing they don't work would be like arguing that cannons don't work - they do and that's why people keep using them. They're like barbed wire for tanks - you can get through barbed wire laid across the ground but it forces you to stop and deal with it under fire which makes the attacker's job harder.
But you're smarter than all the armies in the world i guess and we all know physics changed recently so what worked in the past couldn't possibly work now
ROFLMAO.
Give it up man
Seriously - this isn't some big super secret or anything, if you've studied even a little military history or modern military conflict you'll see this plenty. They're not meant to be a permanent tank barrier - nobody is going to say 'well we can't possibly go that way, there's minature cement pyramids!". They're ment to be in front of a defensive line to force tanks to have to stop to deal with them so guys with other tanks or cannon or missiles can shoot them up while they're slow and vulnerable.
