Future Russian armored divisions will have I assume three brigades of three battalions each ? How many tanks and IFV are in a battalion ? I assume the plan is to equip armored brigades with T-14 and T-15. Will motorized infantry brigades get Kurganetz or T-15 ? Where do the Bumerangs fit in
The equipment of an armoured division was dictated by several factors... the terrain it would operate on, the sort of enemy it would face, its distance from the front lines in any future conflict, and the sort of thing it was near... ie what was it protecting.
There were pretty much two basic types of division... tank heavy and infantry heavy but both had both tanks and infantry and were useful for different types of opponents on different types of terrain.
There will be rather more different types of future Russian armoured divisions.
The whole purpose of vehicle families is to reduce the different types of vehicles within each division.
In a tank division now you have a huge number of soft skinned vehicles that can be defeated with relatively light anti armour weapons.
Future Heavy tank divisions will be armata based. Future heavy motor rifle divisions will be armata based. That is the whole idea.
Depending on the mobility level required future medium tank divisions might be Kurganets based if there are few roads and lots of swamps and difficult country. In areas where roads are plentiful then a medium tank division might have boomerang based divisions. They wont mix them because the situation and location will either suit wheeled or tracked. The motor rifle units will use the same vehicle base so the logistics tail need only carry equipment and tools and spares for one vehicle family type.
For light recon type units and for light coin operations the typhoon will be standard.
Previously if the terrain was poor then BMPs would be preferred over BTRs due to their better cross country performance... in fact in snowy regions MTLB based troop transports were preferred to BMPs for the same reason.
Currently here are 3 types of motor rifle brigades:
1. Equipped with BTR-80 APCs. These units will be reequipped with Boomerang APCs/IFVs.
2. Equipped with MT-LB APCs. MT-LBs will be replaced with Kurganets APCs/IFVs (Mostly APCs, I think)
3. Equipped with BMPs. Most of these units are using the BMP-2 variant, but there are several brigades that are using BMP-3. Older BMP-1s are retired and are kept in reserve. Kurganets IFVs/APCs (Mostly IFVs) will replace the current BMPs.
For future armored brigades, I'm not exactly sure, but I think they will have to be equipped with T-15 heavy IFVs, since it's based on the same platform as the T-14, and we are talking about Armata brigades.
Kurganets brigades will get Kurganets vehicles for troop transport or MBT or ambulance or anti tank or anti aircraft and everything else.
Boomerang brigades will get boomerang vehicles for troop transport or MBT or ambulance or anti tank or anti aircraft and everything else.
Armata brigades will get armata vehicles for troop transport or MBT or ambulance or anti tank or anti aircraft and everything else.
That is the whole point of vehicle families.
ZU-23-2 23mm (it would be an improvement to see them replaced by ZSU-23-4 Shilkas).
That is not how it works... if they only had ZU-23-2 then the ZSU-23-4 probably would not be a suitable replacement. Some sort of towed twin barrel 30mm cannon would make rather more sense.
2B9 Vasilyok 82mm (it would be an improvement to see them replaced by other portable/man-portable mortar of 120mm or of 82mm).
The Vasilyok is a potent little weapon that is relatively mobile... being a wheeled system. I really could not see a man portable 82mm weapon properly replacing it... the 2B9 has a four round clip magazine and is fully automatic. You could not replace it with a hand loaded mortar and still retain the same performance.
As shown in Syria the ZU-23 has a range of uses against both ground and air targets and would not be so easy to replace in some roles.
For instance replacing it with MANPADS would take away its ability to hit ground targets effectively... or small UAVs with small IR signatures...
You can't say they need to upgrade to this or that system without knowing what they are likely to go up against or what resources they have or have not got... and indeed what terrain they need to operate on.
If they can only deploy by helicopter to small clearings on the sides of hills then the ZU-23 is rather more use than a Shilka for example.
