> The IRGC and Basij effectively do not have a chain of command and are effectively moving and acting by momentum
This was by design via the mosaic defense tactic.
They know the US prides itself on decapitation strikes, "taking out the leader of x" was a monthly headline during our time in Iraq, Afghanistan, and during the events of ISIS/syrian civil war. It's how the special forces operated, taking out a "leader", collecting all the names they could find in their possession, and taking those guys out. In the later days of Afghanistan, they stopped even trying to find out who the names were. If you were some mid-level Taliban member's dentist, you'd be fair game.
So Iran built a defense for that, a military that does not need a central command to continue fighting. They have their orders and they'll continue to carry them out. Completely bypass the benefits of highly accurate munitions, cyber intelligence, etc.
That's the same reason the first round of the Millennium challenge won outright. The red-team leadership knew to not expect last year's war today, and used their brains to exploit the weaknesses of a highly mechanized and sophisticated military.
What would such predelegated instructions look like, how large is the state space in that flowchart? How effective is control theory with a tiny state space? This doesn't sound like a survival plan, but a self-splintering plan: some military units will capitulate or defect while others fight on, when pushed till the edge, or is there some kind of direct-democracy-within-the-IRGC? that doesn't sound plausible...
Basically sounds like the military from Imperial Japan during the end of WW2, with scattered units continuing to fight, surrender not believed an option, not aware, or in disbelief that Japan has surrendered...
Let's hope it doesn't have to lead to the same conclusion?
The Swedish military famously works the same way (or at least used to) - they're trained to uphold the Swedish constitution themselves regardless of what their leadership says, with the result that they saved many lives in former Yugoslavia despite orders not to intervene: https://www.realcleardefense.com/articles/2017/09/20/trigger... .
This isn't a complicated war. The US can't and won't do occupations, so the only thing you need to do is cause problems till they leave.
Iran doesn't have to conventionally defeat the US military and can't: so they're just not doing that, and instead going after valuable economic targets which are politically sensitive to Americans and impossible to defend since they're risk sensitive.
