I believe these are new (for here) photos of Numba One MBT of World in construction.
 

 
This CAD drawing also shows glorious thickness of hull protective scheme.

General Dynamics UK have created a virtual expo complete with a 3D model viewer for Ajax and Foxhound:

Interesting things like an electronic drive system for Foxhound:



and the world's most useful periscope:

The .50 cal is the price.

T-14 at IDEX will be a mock up. But interesting new info:
- FCS can do automatic target search and recognition
 
- New (and better) footage of shell ejection.

A new K2 variant has made it's debut at IDEX 2021, the K2M.
 
From what I all can see it's an offshoot of the K2PL though with minor changes, the hard-kill APS has been replaced with the soft-kill APS system (similar to that of the normal K2, you have the soft-kill radar and the rotatable smoke grenade launcher). You also have additional cage armor applied to the turret bustle. 
 
Hopefully more and better images pop up.
 

The side turret armor of the K2 has always thrown me for a loop. Maybe there's more than meets the eye but it's hard to say. 
 
Regardless here's a picture from one of the discussions on the Korean side of the internet on the protection of the side turret wall
 
And the unwatermarked slides that SH_MM posted

Edit: More pics from different angles in this thread:
 

The second one in particular reminds me extremely heavily of the Type 89 and Desert Warrior.

"Type 1": 25 tons, amphibious, 30mm cannon

 
"Type 2": 30 tons, not amphibious, 35mm cannon, equipped with ATGMs

Some historical but relevant stuff. What could have been but was not. In Lešany museum near Prague you can find a prototype of Czechoslovak SPAAG Strop II. This system placed on a modified Dana chassis was being developed during late 80' and early 90' but ended with the dissolution of Czechoslovakia. 
 
I'm posting it because it had a completely unique targeting system which is IMHO still relevant for the future because it was completely passive. It combined passive radioelectronic locators with optical guidance. It had two passive locators, one for survilance (PRUS-P), the other for targeting which was used to direct the optical channel towards the target (PRUS-Z). The passive locators also worked as a passive IFF (there was active IFF as well). The system had only daylight channel but it was meant to be updated later. The system was armed with 2A38 autocannon and Igla-1 missiles (both for standardization with the WARPAC armies at the time when the development started). It could not fire on the move but just like the night channel this feature was planned to be added later. 
 

Photo is my own (many more in the linked article). 

Something that's fairly old (2009) but is interesting nonetheless. South Korea messed around with a camo system similar to that of the Saab Barracuda on the XK2 and K9 though I have only seen one picture of it mounted on the former that isn't a scale model. Not entirely sure what happened to the program though it's probably safe to assume it was quietly shelved.

  Maybe this will be interesting for people outside of Russian defense-themed forums, a taste of one of many battles between Kharkovite mujaheeds and warriors of the Church of Glorious T-80, raging across internet for decades in endless war between opposite piston diesel worshippers and Gas Turbine votarists to find out which one was worse:

thx @David Moyes
but i couldn't get the spoiler done right

Found a few higher resolution photographs from the recent North Korean military parade. We didn't have a topic for BEST KOREAN armored fighting vehicles, so here it is.
 
New main battle tank, Abrams-Armata clone based on Ch'ŏnma turret design (welded, box-shaped turret) and Sŏn'gun hull design (i.e. centerline driver's position). The bolts of the armor on the hull front is finally visible given the increased resolution. It might not be ERA given the lack of lines inbetween. Maybe is a NERA module akin to the MEXAS hull add-on armor for the Leopard 2A5?
 
Other details include an APS with four radar panels (the side-mounted radar panels look a lot different - and a lot more real - than the ones mounted at the turret corners) and twelve countermeasures in four banks (two banks à three launchers each at the turret front, two banks à three launchers on the left and right side of the turret). Thermal imagers for gunner and commander, meteorological mast, two laser warning receivers, 115 mm smoothbore gun without thermal sleeve but with muzze reference system, 30 mm grenade launcher on the turret, six smoke grenade dischargers (three at each turret rear corner)
 


 
IMO the layout of the roof-mounted ERA is really odd. Either the armor array covering the left turret cheek is significantly thinner than the armor on the right turret cheek or the roof-mounted ERA overlaps with the armor.
 


The first ERA/armor element of the skirt is connected by hinges and can probably swivel to allow better access to the track. There is a cut-out in the slat armor for the engine exhaust. Also note the actual turret ring - very small diameter compared to the outer dimensions of the turret.
 
Stryker MGS copy with D-30 field gun clone and mid engine:

Note there are four crew hatches. Driver (on the left front of the vehicle), commander (on the right front of the vehicle, seat is placed a bit further back), gunner (left side of the gun's overhead mount, next to the gunner's sight) and unknown crew member (right side of gun's overhead mount with 30 mm automatic grenade launcher mounted at the hatch). The vehicle also has a thermal imager and laser rangefinder (gunner's sight is identical to the new tank), but no independent optic for the commander. It also has the same meteorological mast and laser warner receivers as the new MBT.
 
What is the purpose of the fourth crew member? He cannot realistically load the gun...
 
The vehicle has a small trim vane for swimming, the side armor is made of very thin spaced steel that is bend on multiple spots, so it clearly is not ceramic armor as fitted to the actual Stryker.

 
The tank destroyer variant of the same Stryker MGS copy fitted with a Bulsae-3 ATGM launcher.
 

Note that there is again a third hatch with 30 mm automatic grenade launcher behind the commander's position. Laser warning receivers and trime vane are again stand-out features. The sighting complex for the Bulsae-3 ATGMs is different with a large circular optic (fitted with cover) probably being a thermal imager and two smaller lenses visible on the very right (as seen from the vehicle's point of view) probably containing a day sight and parts of the guidance system.
 

Non line-of-sight ATGM carrier based on the 6x6 local variant of the BTR, again fitted with laser warning receivers and a trim vane. There are only two hatches and two windows, but there is a three men crew inside.
 
 
There are a lot more photos here, but most of them are infantry of missile system (MLRS' and ICBMs).
