Documentation of M1A2 / M1A1 HC Hull Armor Composition (1996–2016)

Yes, that is what he claims is previously defined and that they skipped capitalization on making that the standard for the table. I have not see a previous definition with that term capitalized.

You have not shown that there are previously defined versions of those other things that they also skipped capitalization on making that the standard for the table.

You used the exact same kind of argument to argue in favor for it previously. How does me using it now make me desperate but not you desperate previously?

The DoD defined this exact term in September 2000, the same year the AIM entered service.

HRA Consultation No. 26-MF-7555-00D explicitly refers to the testing of an Abrams Heavy (DU armored) tank.

It puts DU armored in parentheses right next to Heavy. That is the official military definition. Heavy equals DU.

If your theory about it just being a descriptive word for weight was true, the CBO would have labeled the IPM1 as Heavy Armor too. The IPM1 gained substantial weight over the base M1. But they didn’t. They listed the IPM1 as Improved Composite. They only used the term Heavy Armor for the variants that the Federal Register and DoD confirm are radioactive.

Found it. Yes the Armor School trained ABRAMS tank personnel on depleted uranium characteristics and risks. The 5 training tanks with hulls were most likely part of that program.

Sure, that doesn’t mean the CBO uses it that way. That would make using the term “heavy armor” at the start of a sentence impossible without it changing meaning.

Also, that doesn’t mean there is DU in the hull either.

The worse part about all of this is it takes away from the argument of the Hull armor just having received a better composite array or replacement of materials with other non DU materials that provide a better form of protection.

The Congressional Budget Office audits the Department of Defense. They utilize the specific technical nomenclature of the agency they are auditing.

The Federal Register (1998) defines the Heavy Armor System as the radioactive armor package.

The DoD Health Risk Assessment (2000) explicitly defines Heavy as DU armored.

The CBO Report (2006) confirms Heavy Armor was added to the hull.

If the term was merely a descriptor for weight, the IPM1 would be listed as Heavy Armor. It gained significant mass over the base model. The CBO listed it as Improved Composite. The distinction is based on material composition, not sentence structure.

It’s not an audit, it’s a study putting forth alternatives for a future heading.

Yes. but doesn’t state if the DU package IS the Heavy Armor System or if the Heavy Armor System simply contains the DU packages along with other non-DU parts.

Heavy is the name of those tanks . They are known to have DU in the turrets only.

Not necessarily the same term though.

There are several steps here with no clearly defined thing where you assume a definition that isn’t explicitly stated and isn’t semantically unambiguous.

You continuously fail to see this and i have given up all hope of ever making you realize that the things your are pointing out are ambiguous in their interpretations. I have given up all hope of you realizing that you are also cross referencing over several different US government instances. Two things that make this non valid as proof for reporting historical issues to Gaijin.

Can’t you find a document for disposure of the Abrams models of the years found, and if it mentions having procedures for the disposure of radioactive elements in the hull wouldn’t that basically be like a way more conclusive evidence for your point than trying to use procurement records? I mean it would likely very clearly distinguish the hull from the turret, and would have to then label hull procedures with a radioactive materials warning and such no?

Both are easily true.
The DU package is the Heavy Armor System
The Heavy Armor System can contain non-DU parts. The LFP and Turret cheeks aren’t the only armored sections of the tank.

OK just out of question regardless of whether or not the tank uses DU we are all in agreement it does say Heavy armor upgrades to the hull and turret in these packages and documents?

And that’s the main issue. It’s ambiguous and not clearly defined. In several places of the documents so there is no singular unquestionable conclusion.

problem is that even if it say “SUPER DUPER IMPROVEMENT” gaijin wouldnt even consider because they want actual number
the reason why DU in the question here is because im pretty sure gaijin maybe would consider it because there are info regard on its protection in that manners, so thats why people report about DU - because there are numbers for it

This is my issue with it If we don’t know the numbers but we know its an upgrade of the previous generations just add enough armor to make it a balanced plate. Make it enough that the top rounds can go through it, but older darts can’t.

This makes sense, since the M1A1HA (Heavy Armor) was the first version of the Abrams with DU armor, while the M1A1HC was an upgrade with a better version of DU armor. On the other hand, there would be the Australian M1A1AIM, which had its DU armor removed and fitted with a conventional but modern one.

“no number no upgrade”
it has been like that for a while, gaijin is scared because if they make an educate guess and up the abrams armor the RU main would cry because they cant W and click easily anymore and has to aim for weakspot

That is exactly part of the problem. Gaijin wants distinct numbers but they themselves cannot post the sources or otherwise of changes and adjustments to vehicles already in the game for the USSR and China Nations. I understand changes for balance but when you have certain vehicles underperforming when compared to others you either buff the ones underperforming or you nerf the overperforming ones. Instead they continually buff and add broken things to nations that are already so far from “Historical” that it clearly shows the intent. Meanwhile we have to try and find exact texts listing the procetion of X from X at X distance from X angle. We get to play document Gymnastics because they want the exact specification when they can look at the actual documents available and have been provided in reports and otherwise and see that there is CLEARLY improvements or upgrades over the previous models and go okay so lets increase it by X to keep it fair for a balancing prospective.

Lets be real if the Protection values of A2, A2 Sep (1,2,3) were declassified Gaijin would look at them and go NOPE thats unfair for the game. Meanwhile we get Kontact-5 defeating DM53, 829a2, and l27a1. All rounds that had been developed to perform better against the REDFOR ERA.

You are misunderstanding the point of the Parathensis. Abrams Heavy (DU armored) tank. Heavy = Descriptor = DU armored as the Heavy is being described as the Depleted Uranium Armor. Thus the CBO Report using the EXACT Descriptor of the Armor on the HULL and TURRET. Heavy = DU End of Story

They upgraded the DU armor with the M1A1 HA+, the M1A1 HC uses the same armor as the HA+.

(M1A1 HA) → (M1A1 HA+) → (M1A1 HC) → (M1A2 Block II MBT).

That’s not how deduction works.
