The main work for the Leopard 2A7V uppgrade is done by KMW. The contract was not awarded to Rheinmetall, this company acts only as a sub-contractor (i.e. parts for the Leopard 2A7V like the gun and FCS are made by Rheinmetall). The lion's share of the work is done by KMW and the schedule is mostly a result of their work backlog:

Before the first Leopard 2A7V will be delivered to Germany, a part of the Danish order (who are upgrading their Leopard 2A5 tanks to Leopard 2A7DK) has to be finished. They already received their first Leopard 2A7DK tank:

There are two models of the Leopard 2A7DK; one is pretty much identical to the Leopard 2A7V, the other will retain the shorter gun barrel and might lack other features as well.
 
The only reason why I think one could blame Rheinmetall for the slow delivery is the fact that the whole deal was delayed by two years - originally the contracts were to be signed in 2015, but it was signed in 2017 after Rheinmetall and KMW couldn't agree on how the money was split between the two companies. As far as I understand KMW's production capacity is limiting the upgrade. KMW doesn't have a fully operational Leopard 2 production line in Germany, which is why some parts for the Leopard 2 tanks ordered by the Qatari military were in fact made in foreign countries. I.e. the basic hull structures for the Leopard 2A7Q were made in Greece, which then were transported to Germany. The turrets were made in Kassel (KMW's facility in Kassel is very close to Rheinmetall's Kassel facility, where the gun and FCS were made) and then send to Munich. In Munich the Greek-made hull structures were fitted with all components and the turrets.
 
Qatar ordered its 62 Leopard 2A7Q tanks, 24 Panzerhaubitze 2000 artillery systems, unknown number of Dingo 2s and 32 Fenneks in 2013, but in 2016 only about half of the vehicles had been delivered. If you add the Danish contract to the mix aswell as orders from the Bundeswehr (Dingo 2s, Fennek JFST, and some of the Boxers are made by KMW) and other NATO countries, then it is easy to see why KMW needs so much time to deliver the German Leopard 2A7V tanks.
Rheinmetall also has lots of orders (most Boxers and most parts of the Puma + the final integration are made by Rheinmetall), but it is a much larger company (~23 thousand vs ~2.7 thousand employees) and much more open for international cooperation (only 25 out of 211 Boxer CRVs for the Australian army are being made in Germany, the work for only 8 full and 12 partial Leopard 2PL upgrades out of 128 tanks will be made in Germany).

"Not sure the year on these pictures, but we are going to guess they date back to when the Crusader program was still alive, so early 2000’s."

A pair of interesting photographs posted by Damian from @Walter_Sobchak's blog, not (just) because they show an Abrams testing hydropneumatic suspension but because they appear to show the glacis is thicker than it is around the driver's hatch.
 

The Guardium with that kit was used in limited service in highly hostile areas, and as I understand also in airport security.
 
This one specifically was equipped with an HMG just to show you can properly activate it, so they didnt add a swivel mechanism on it. Just a feasibility test really.
 
The Guardium was since further developed and seems to have dropped that heavy armor kit, and recently was tested with an RCWS.
 
I think only the recent variants are in service.

My bad, but wasn't it one of the prototypes also for the Europanzer? 
 
This image is commonly used for the Europanzer. 

That's an AMX 30 prototype(1961)

Same tank that Zuk posted.

An undisclosed Asian country ordered ADS in 2011, when it wasn't ready for service. Maybe that's Singapore. On the other hand Turkey has been requesting the system since 2016...
 
 
You mean like this?

Interim results... note that Romania is missing (no show?).

I do believe that is an M1A2 SEPv2, not all of them have an RWS. Trophy can be mounted on the USMC’s M1A1 FEP.

And so it begins:
 
 

It's where the crew will insert a faulty shell, instead of dumping it where an enemy can potentially grab it and sell it.

M1A2 going old school.

Solid green looks much better than camo, IMO.

Does anyone know where the gun elevation mechanism of the Leclerc is located  and how it looks like?
 
Using DarkLabors older CAD model i am getting the impression that the marked object is part of the gun elevation mechanism:
