Recent news on the Tosan:http://www.yjc.ir/fa/news/4025415/-%D8%AA%D9%88%D8%B3%D9%86-%D8%AA%D8%A7%D9%86%DA%A9-%D9%88%D8%A7%DA%A9%D9%86%D8%B4-%D8%B3%D8%B1%D9%8A%D8%B9-%D8%A7%D9%8A%D8%B1%D8%A7%D9%86%D9%8A
- Based on the FV101, officially* confirming what many have suspected.
- Equipped with the Toofan-5 ATGM. This is unsurprising given the Jordanian upgrade of the same type posted above.
- 8x Smoke-grenade launchers, identical to Iran's FV101s
- First entered production in 1386 (2007/2008), but only entered mass production a year later (2008/2009). It's interesting that the public discourse on both the Zulfiqar and Tosan include delays by little-specified "problems", with "mass" production occurring about one year later. I doubt there's much significance to this, but there may be. This is consistent with brief announcement
in 2008 by an IRGC Col. Although a year later, in 2009, the Col. said the same exact thing
- Fitted with a "battle management system" (سیستم مدیریت نبرد) and digital communications(دستگاه ارتباطی دیجیتالی), which is used to network with other units. Networking may be a vacuous buzzword nowadays, but it's that way for a reason - information dominance is what wins Western-style armies their conventional victories.
- 90 km/h on-road, 65 km/h off-road. This isn't that different from the FV101s top speed of 80-87 km/h. I wouldn't be surprised if the engine was replaced, as have many other users of the Scorpion have done.
- 12.7mm and 90mm guns. Cockerill Mk III for sure. It theoretically could be the medium-pressure Mk 8, but I think the chance of that is as close to zero as you can get. Of course, the big question is what kind of ammunition they're producing for the gun. My guess is HE/HESH. Given the accompanying Toofan, there's less reason to invest in high-quality HEAT warheads. Something to keep in mind is the increase in weight: the main-gun and ammunition adds in 650 kg, the DShK adds on around 50 kg, while the TOW (with two tubes) roughly another 150 kg - a 10% increase in weight.
* - At least I'm hoping this is more than just speculation on the part of the article's author.
Looks like they are still used as scouts... I wonder if each Division has a Cavalry Sqdrn (Battalion) like the USA or each Brigade has a Scout Troop
While I can't speak to their deployment at the division or regional command (army? corp?) level, in the 16th AD at least, each brigade is equipped with some FV101s, however many that may be. Probably platoons or companies as part of a larger motorized recon battalion. I can't imagine Iran has enough left to field homogenous recon forces like they once did.
