We need the Abrams with MTAS:

This would be a cool modification ala T-80B 1 protoype with thermals style

That is the “I’m dead” light for CVTESS, which is basically a vehicle laser tag system used for force on force training. You will find it on any combat platform conducting large scale force on force like at the National Training Center.

M1A1 (?) fitted with a Multisalvo Smoke Grenade Launcher:

Here’s also a Bradley with the Vehicle Integrated Defense System (provides LWS, MWS) since it doesn’t have its own thread:

Seems like the Rheinmetall ROSY is modeled on the SEP/SEPV2 on the dev server:

Abrams blow out panels are by design meant to protect against explosions. Not just deflags. There is no overpressure in the crew compartment due to this cam locking system.

FIG. 1 is a plan view of the U.S. Army’s M1A1 Abrams Tank 10 having turret 12 mounted thereon. In the rear of the turret is bustle zone 14 where a closed ammunition compartment 20 is located, the top of the ammunition compartment being formed by blow off panel 16. Panel 16 is designed to break away should an explosion occur in the ammunition compartment. The force of any explosion will be directed upward, whereby the tank crew members in the turret will survive and the tank may be operable enough to carry the crew from the battle zone. Blast door assembly 18, by which the crew accesses ammunition in compartment 20, is schematically designated by shed elongate rectangle 18 in FIG. 1.

With the recent addition of the M1A2T added to the Chinese tech tree, I believe this thread deserves some more attention.

Requested changes/additions:
Add M1A2T to the variant list. Technical data can be found here: (M1A2T Abrams: The ROCA’s Steel Fortress)
M1A2 SEPV2 now has Rheinmetall Rosy 360 degree LWS and additional smoke grenade launchers. Could be added to a new category, or smoke grenade launchers added under armament.

Add the following bug reports:

You missed an OG turret ring ticket
https://community.gaijin.net/issues/p/warthunder/i/hn6WHPVB7r3K

That’s already in the original data sheet. I made that one

But yes, the turret ring is arguably the biggest bug of this vehicle. Here hull underside slope remains consistent up to the turret basket, while the topside decreases slope upwards. Thickness should vary between 200 and 50

There is also gap between the hull ring and the turret ring, which is understated by a lot of people. Should look more like my drawing here. This would add another 19mm of armor to the whole turret ring by default, eliminating a lot of low caliber IFV APDS from being able to penetrate at more than point blank range.

As shown by this photo, the turret itself was conveniently blown off while leaving the attached ring and turret basket inside the hull. Turret ring and hull ring should be properly seated and 100% sealed

Most technical drawings I’ve seen also show a slight gap though.

Here’s a comparison I made a while back:

Sorry, to clarify, I’m talking about a horizontal gap between the two turret ring models, not vertical.

I agree with you that the actual turret alignment issue is kind of a made up rumor. If you look at the photograph I sent, I am referring to the interior turret ring (in real life attached to the basket) in game attached to the underside of the turret armor module does not match the diameter of the hull turret neck.

In the destroyed Abrams photograph I sent, you can see the turret seats perfectly into the hull with no gap for spalling to enter through. This is the only photograph that actually proves this since the turret basket and ring is actually part of the turret, but was left inside the hull when the vehicle was destroyed.

Here is a more helpful angle. As you can see, the actual turret ring (green) does not match the diameter of the hull turret neck (yellow), allowing for spalling to enter regardless of penetration of the internal turret ring. So basically the purpose of having this issue fixed is, if the actual hull turret ring protection were to stay how it is now, the turret ring would effectively be 70mm of armor, rather than 50.8. Which, with the angle it is built at, would actually be enough to rule out most small caliber IFV and SPAA APDS shells. Of course this is still a minor issue in comparison to the lack of volumetric armor in the turret ring but it is still something. So, overall there are two issues. The inside of the turret ring is just totally modeled wrong, and it also needs to be changed to volumetric.


Now my original drawing above should make more sense.

If you take a look at the hull ring all by itself, you can actually see how the turret will seat properly. Penetrating this module alone cannot result in spalling entering the fighting compartment, it must also penetrate the turret’s own ring. Theoretically speaking, this could result in a MUCH larger increase in armor protection, but I have nothing to substantiate that so I just stuck with Gaijin’s guestimate of 19mm


A more accurately modeled turret ring would still have a gap that you described, which the in game model doesn’t have, but it would be a weak spot closer in size to a Leopard-- so basically negligible.

Here’s another image that might be helpful.

Yes that is a very clear image, that’s actually one of the ones I included in the report but it is hidden from view

That image also shows the thicker upper plate armor around the fuel cell on the left and right hand side beneath the fuel caps

In all seriousness the Booker is the most DOA item to come to the US in a long while

It is a tragedy. And for the same amount of labor, they could have fixed all of the discrepancies with the entire Abrams line, and added the SEPV3 at the same time.
