Here is the tech tree update after rank 8 addition. I’ve sorted many of these vehicle’s ranks using in-game tree as a references. This includes some BR changes based on other related vehicle’s performance (like how the Rakhsh with ZU-23 got its BR bumped due to the BTR-ZD also got a bump), as well as a few new vehicles.
Note that I took a bit of liberty to increase the BR ceiling to 12.3 myself to match to that of the current top tier air BR, since I find a bit odd that Gaijin decided to kept ground BR ceiling at 11.7 despite adding more advanced vehicles at that BR.
First off, I’ve decided to add the M151A2 TOW into the tree, foldered with the Safir (Toophan). This is partly due to I found an image of these vehicle in service with Shahist Iran and to make transition to rank 6 a bit smoother. The M151A2 would use the same TOW/I-TOW missile as other basic TOW carriers compared to the Safir that would get more advanced Toophan variants.

Second, I’ve bumped up the BR of the Soheil to 9.7, as I found that the MANPADs that were equipped onto it is the Misagh MANPADs (though the exact model of the launchers is unknown). These MANPADs has a maximum range of 5 km, which would match with many Stinger-equipped vehicles.
The Majid also got its BR bumped up as well, as the missile it is using has 14 kg of warhead, and that the vehicle has a salvo fire/fire-and-forgot capability.
Also, I’ve added an early version of the Herz 9 system with two missiles instead of four, and with shorter range.

Finally, I’ve added two new vehicles into the tree.
The first is what I considered a “meme vehicle” for how weird it is, and that I’m not sure if it would work until the BTR-ZD prove me wrong. That vehicle in question is the Heidah 7.
As you can see, the vehicle is really strange. Being a modernized BTR-60 with tons of ERA on it.
More details about the vehicle:
The Heidah 7 is basically a further development of the BTR-60 modernization program of Iran, which saw the vehicle typically being armed with an open ZU-23 turret. Though in the Heidah 7’s case, it forgoes ad-hoc modification in favor of a delicated turret with a single ZU-23 autocannon and fire control improvement instead.
The rather questionable choice of mounting ERA on a light vehicle is to protect it from various chemical projectiles, such as RPGs and ATGMs. To which the vehicle is expected to face, since it was designed as a scout and recon vehicle with convoy raiding capability.
Another one is a contender for top tier AA for Iran (should the BR ceiling increases), that being the Zubin air defense system.
Spoiler
Currently, little details is known about the Zubin system, as it is currently still under development.
What we did know about the system is that it was first revealed in December 2022, it was based on the Mercedes-Benz 2631 truck chassis, and that it uses vertical-launch SAM with a range between 15 - 25 km as its main armament.
The system appears to be infrared-guided missile system with built-in radar.
As a sidenote, I’ve found this random image of an Iranian M47M with what appears to be ERA bricks and some fire control module. I’m not quite sure about adding it as a separate vehicle yet, since there’s literally only one image of this specific configuration I could find. Though I think it might work as a modification for the M47M.
