- STANAG 4A/4B for Mineblast protection with the same mine resistant seating system as on the Hawkei PMV

I count 8 in there.
And aren't those seats - Australian government issue seats from the Hawkei, to be common between Lynx and Redback?

compare to CV90 mkIV
floor of as21 perhaps 300mm thick, no intrusions VS floor of CV90 looks like sits right above torsion bars

I would suggest the RWS integration will be partly responsible for the command, control, communications, and computing (C4) capability, basically (Kongsberg) an integral part of the K9's digital architecture and fire-control system. Otherwise they would just chosen Australia's EOS RWS for the australian market.

That is where the coax lives.
isn't the coax on the starboard side? or did it swap side for Australia?

It was seemingly missing the radar panels and EO sensors for Iron Fist.
interesting detail on the port side of the gun shroud.

The 3rd AS21 prototype has left Korea and is en route to Australia. It departed from Masan Port on the 18th.
According to the press release (machine translated), "prototype 3 will be officially delivered to the Australian Army in the middle of next month along with the 1st and 2nd units sent to Australia in July, and will be used for a full-fledged test evaluation from February." (Link: https://www.news1.kr/articles/?4155699)
something that is standing out is that both as21 and kf41 seem to have the drivers position a lot further aft than CV90 or KF31....

periscopes seem to at front of AS21 drivers hatch, but halfway back of KF41 hatch

Precisely the type of MLU needed to keep IFVs relevant for the upcoming decade or so.
I do wonder if Iron Fist is capable of dealing with drones and diving munitions which are the latest hotness or if that will require another system later on.
4 radars cover 360 horizontal, so it should be good for upto 45 degree from horizon, I doubt the radar covers above 60 degree from horizon, 45-60 degree is iffy. i do notice the radars are canted back a little...
it would only take 1 additional radar to sense the top, thats implies a 1/4 price increase

Military track (in peacetime) is friendly to all road surfaces simply as load is distributed so well compared to wheeled vehicles. Exceptions are when the midden intersects the ventilator and we revert to steel track and even rubber pad or band track does rip up bitumen if you pivot turn. Less damage on dirt as less traction. (less resistance to pivot)
what I'm trying to understand, would a carefully driven rubber banded IFV be capable of travel on australian/asian roads without causing damage. because excavators have a bad reputation for tearing up the roads. we have plenty of that thin cheap, spray seal (chip & seal) road The Nature of Sprayed Seals | Austroads.

Question, how friendly (or otherwise) are rubber tracks to dirt roads. I assume the rubber tracks are still too aggressive to place on bitumen roads, but do they tear up dirt roads too? (Ie australian rural dirt road, but still traversable by RWD. Ie ford falcon)

No, they are not. You may not know what the relevant performance metrics are, if you come to this conclusion...
I'm sure I don't know what the relevant performance metrics are,
however using the public advertisments in my country, I get
COAPS 2016 COAPS_2016.pdf (elbitsystems.com.au) FLIR •target NATO NFOV (DRI 10.5, 4.5, 2.2) km
R400 R400BrochureAUS_WEB.pdf (eos-aus.com) thermal imager•target (DRI 13.7, 5.1, 4.0) km
If I were to draw a conclusion, it would be that 4 years is currently a long time in sensor tech, and that COAPS2016 is different to COAPS today.

just a thought, now that Apache are joining ADF, the M230 chaingun will now publicly be part of ADF. which is an option for the redback's R400 RWS. (but why bother when there is a real 30mm already on the turret)
-
hmmm helicopters are army, apache uses m230, ADF will now have logistics to support M230

Looks like it is now official: Tiger is out and Apache (Guardian) is in for the Australian Army.
https://www.minister.defence.gov.au/minister/lreynolds/media-releases/future-ready-strengthening-armys-armed-reconnaissance-capabilityNo one is surprised. The lack of availbility of the OZ tiger was legendary.
"On average, only 3.5 aircraft in the operational fleet of 16 helicopters were available on any given day in 2015,” it said. This was below targeted readiness of 12 aircraft."
I expect the EU tigers were much better, in theory its the same bird. In reality....

Not a fan of using RWS' optics as independent commander's sight. There should be a noteworthy performance difference compared to using the independent commander's sight as RWS.
EOS r400 optics etc are better than elbit's 2016 COAPS, but i can't find pdfs about current COAPS, I notice the AS21 COAPS has differing lenses to earlier generation.
Other notable point is that EOS r400 seems to duplicated its dual axis stabilisation. I guess that allows the sensor's slew and elevation to be more rapid and more stable than it's weapons.

How is it supposed to work?
That's purely secondary property and hardly a reason to carry it. The reason for slat armor existence is increase of surivability for the cost of extra weight, ridiculous dimensions, worse driving performance and harder accessability of most of the vehicle area. However it works only against very old HEAT grenades and only sometimes. It doesn't work against ATGM and newer RPGs at all (even against pretty old ones like RPG-18). When the vehicle is equipped with APS, which can deal with all those threats much better, there is no reason to diminish its performance by adding the cage.
Modern slat armour is about 10kg per square metre coverage. (See hawkei above). It also has electric cunning to defeat more modern rpg. So weight is almost inconsequential, but maintainability and robustness could be an issue. As both redback and lynx come with ironfist's radars, the obvious option to up armour for pre deployment is simply to plug in larger/ and or additional launchers for the APS....so perhaps that is the future. But guessing the australian army conservatism, i would expect both. Additionally i would expect users of either/both lynx and redback to eventually add some hull APS launchers, tied to the turret's radars.

Why to install slat armour on a vehicle with APS? Slat armour severly degrades vehicle mobility and somewhat protects only against very old anti-tank weapons which shall be an easy prey for the APS.
Maybe slat armour will end up optimised for 57mm HEAT spam.
Besides slat armour should be cheap to repair.

What is that spare prop looking thing on the side?
It looks like its there to demonstrate the side can carry stuff, if needed.

by that article, the Redback is wider than the Lynx, by the picture the tracks on the Hanwha are as wide as the combo of Lynx track + side skirt.
the ride will be different between the 2 vehicles. more rubber in contact + more tension along the track
height seems similar, but hawha has both taller hull and nil suspension intrusion into hull. why?
