M1 Abrams Depleted Uranium Armor and M829A3

Depleted uranium (DU) armor

The M1A2, M1A2 SEP, and M1A2 SEPv2 (and certain variants of the M1A1 belonging to the Marine Corps when they used the Abrams tank) all should have DU armor in-game, as documented in various documents issued by the United States Department of Defense and found publicly available on the Defense Technical Information Center. Various documents such as the ones listed below record the M1A2 as having depleted uranium armor, along with other upgrades that are already present on the M1A2 series of tanks in-game.

M829A3 APFSDS-T ammunition

As well as the Abrams turret armor inaccuracy, the M1A2 SEPv2 Abrams is cited to specifically use M829A3 and to have notably higher penetration than M829A2, leaving cause for it to be added as a potentially researchable modification on the M1A2 SEPv2.

Documentation on the M829A3’s penetration. Albeit, these are unofficial estimates and I am aware that Gaijin uses a certain formula to calculate a shell’s penetration and performance, this should be something to note and would, in fact, be more accurate for the M1A2 SEPv2 to have this ammunition at least as a modification after M829 or M829A1 since M829A3 was designed to penetrate explosive reactive armor found on Soviet/Russian MBTs such as Kontakt-5.

With this information provided, I am aiming to make the M1A1 and M1A2 series of tanks more balanced with the tanks that it faces throughout top tier. Despite there being many newer players to the game who buy packs to rush to top tier such as the M1 KVT or M1A1 Click-Bait, there is no doubt that the accuracy in the Abrams tanks in-game is far from truth, and win rates for the United States at top tier has consistently been lower than nearly every other country playable in-game.

Along with the provided information above and the added documentation would ensure that War Thunder is more accurate in what ammunition the aforementioned tanks use and what armor they utilize in later upgrades.
We hope we can get some productive feedback on this soon and work with the community to try and improve War Thunder’s accuracy and community.

Consider reporting a bug report, it should be more useful than moving another argue about the Abrams armor and ammunition.

The Abrams does have DU in-game though. Additionally ammunition is a balancing decision- that’s why there’s no DM73 and DM53 is underperforming, not it mention that M829A2 is a close second place for best shell.
Finally, win rates are 100% a skill issue of the AIM and Click-Bait. Hell, all the dramatic dips above like 6.0 can be directly mapped to a popular and highly advertised premium vehicle.
It’s unsurprising that there are disproportionate dips in wr at the BRs of the Strv 103, TURM III, Turms, AIM/Click-Bait. Even look at how much the Soviet winrate dropped since he introduction of the premium T-80.

I can report this as a bug report, as I’ve considered this an option before and thought a forum post may be more direct and formal. Thanks

Okay first off, why are you citing player skill in a discussion about M1 Abrams?
Win rates, AKA team skill, is off-topic to this discussion.

Now onto the on-topic portion:
M829A2 is already the best MBT round in the game fired out of the 2nd best cannon in the game. Abrams does not need an ammo buff. Signed, an Abrams fanboy.

Second DU armor is already in-game on the existing Abrams. They are slightly more armor than the Sweden trials data because that’s the only publicly available data about protection the armor offers at the time of Abrams introduction into War Thunder.

Steel Beasts uses the same Sweden trials data for their Abrams, and their simulator is used for training.

@WalletWorrier
DM53 isn’t underperforming according to available test data I’ve read in the past.

DM53, like M829A3, is designed with a soft aluminium tip in order to pre detonate ERA. This isn’t modelled in-game which is fair considering even without it it’s still the best APSFDS.

That specific mechanism isn’t modeled, but Gaijin gets around that by letting DM53 and M829A2 defeat K5 protected armor anyway. [Beyond the perforation “limit”.]

I’ve looked more at what a Community Manager on another forum post has said and will adjust what I’ve suggested accordingly. I misread a part of the aforementioned post in where DU armor is modeled in-game and will adjust what I said regarding M829A3, though in a bug report.

Realistically these changes won’t do anything for the WR, and the Abrams is the 2nd best top tier MBT already. Low level US mains will always suck even if the Abrams is frontally immune to everything.

not being able to delete my own posts is great, though I will say that this forum post was an error on my part and at least I’ve learned from it;
Thanks for commenting on the DU armor on the turret as I did not recognize this mistake at first. Forum post not relevant anymore and I’ll reformat a small bit of it into a bug report.

@MightyBaozi you heard the man
