metric or customary units?

Can this tank be serviced and repaired in Europe and the rest of the world with metric tools and screws etc.? -- Espoo (talk) 23:27, 20 January 2023 (UTC)

Given how common US bolts and parts are in the US, that seems doubtful to me. But note that Wikipedia is not meant to be a how to manual type of thing per WP:NOTGUIDE. -Fnlayson (talk) 23:46, 20 January 2023 (UTC)

My question is an indirect way of pointing out that this article is missing essential info, whether the tank is made with bolts and other parts in metric units or not. This then provides the essential information whether or not it makes sense for other countries to buy or temporarily use this tank or not. --Espoo (talk) 00:10, 21 January 2023 (UTC)

If other countries are using Wikipedia as a guide to whether or not to purchase or use a certain, then the tank is probably a bad fit for those countries. They should stick with bows and arrows. As to readers, it's just WP:Trivia. BilCat (talk) 00:21, 21 January 2023 (UTC)

You seem to be unaware of the importance and role of Wikipedia in keeping citizens informed and in being empowered to control and criticize political decisions, especially on issues that are decided mostly in secret. Even most journalists first go to WP to check for specifically things like this issue of metric or not or inefficient mix.--Espoo (talk) 09:58, 23 November 2023 (UTC)

Metric vs. imperial was a major point of contention during the MBT-70 project. It rose to the level of SecDef and Defense Minister, who were still unable to resolve the question. I think it deserves a mention. We should probably have a production and maintenance section. I suspect the measurement issue is a major reason why the U.S. says the Abrams is not suited to Ukraine. Schierbecker (talk) 06:08, 21 January 2023 (UTC)

IIRC, most of not all of the U.S. military uses metric now, but I could be wrong. Or, like most of the US, they use a confusing mix of both. BilCat (talk) 08:13, 21 January 2023 (UTC)

In August 1976 the USA and the Federal Republic of Germany signed an addendum to the 1974 MoU: ‘The Addendum will assure significant stan- dardisation of items that dominate the logistical support of our tank forces, including fuel, ammunition, guns, tracks, engines, transmissions and fire- control. The Addendum envisages both the comparative evaluation of Leopard 2 and XM1 tank designs and the initiation of joint activities neces- sary to introduce these standardisation elements into the respective national programs. It also provides for the possible participation by other NATO nations in these standardisation efforts.’[...]In accordance with the December 1974 MoU a comparative test and evaluation of the Leopard 2 American or Austere Version (AV), was con- ducted between September and December 1976, utilising the same criteria and constraints as used with the two American prototypes. Through the provision of a January 1977 addition to the Addendum to the December 1974 MoU the USA and West Germany agreed that the evaluation of the Leopard 2 (AV) MBT would be used only as a basis for furthering sub- system standardisation between the two tank systems. Among these con- figuration options were the diesel and turbine power packs, tracks and sprockets, metric fasteners, the gunner’s auxiliary telescope, and a turret capable of taking either a 105 mm rifled or a 120 mm smooth-bore tank [...] In the end standardisation between the two tanks, apart from the West German 120 mm tank gun was restricted to common fuel, fire-control modules and metric fasteners and tools at the crew maintenance level. West Germany declared that it could not agree to changes to the Leopard || which would have an impact on cost or production.

So, yes, I believe the Abrams uses metric fasteners. Schierbecker (talk) 06:23, 27 January 2023 (UTC)

As a former M1 tank crewman (I commanded a tank company in Iraq in 2006), I specifically recall SAE (not metric) wrenches in the tanks' toolkit. I believe there is at best a mix of SAE and metric components, as found in many US-made products (see our automobile industry). To the point of suitability for Ukraine, I think the real issues here are the weight of the tank, the complexity of its maintenance, and its fuel consumption.

What are the vulnerabilities?

How is it vulnerable? How can this tank get damaged or destroyed, or prevented from completing missions? Please add a list in a new section. Stephanwehner (talk) 19:01, 25 January 2023 (UTC)

The M1 is extremely vulnerable to tactical nukes. A direct hit or near miss will totally disable it. But I wouldn't recommend that. BilCat (talk) 20:22, 25 January 2023 (UTC)

Thanks. Whether this is the only vulnerabilities, or if there are more, it would be a valuable to address the question in the article. It looks like a significant gap. How can an enemy fight this tank, and win? Stephanwehner (talk) 14:57, 3 February 2023 (UTC)

At the tactical level, like all western tanks, the armor is thinnest on the top of the turret and underneath the hull. Top attack missiles are effective, as are anti-tank mines. Operationally, the M1 uses fuel at a greater rate than some allies' tanks. Therefore the logistical tail is a vulnerability. At the strategic level, we have a vulnerability in political will, whether to fund the military on schedule or to ensure the quality of our youth for enlistment. Both of these issues impact the maintenance and crew of M1 tanks.

The original M1, prior to the hull-mounted NBC system in use today, did have a small vent system in the left rear of the turret that could be attacked with small arms. That vulnerability went away in the 80s from active units, and across all M1s in use by the late 90s. Vasky22 (talk) 17:56, 13 November 2023 (UTC)

Nuclear, biological and chemical redirects to Weapon of mass destruction, so changing it would be redundant. BilCat (talk) 00:05, 26 January 2023 (UTC)

Stop being biased and based on POV

There is no such thing as the Islamic State. It is the so-called Islamic State. You know the official name and the abbreviations ISIS and ISIL. So stop being biased and editing with a POV please. 46.31.112.214 (talk) 06:22, 2 February 2023 (UTC)

Sorry, but that's editorializing, and not permitted. "Islamic State" was its name at the time, and that's why it's used here. You've been blocked from editing this article for edit warring to prevent further disruption. BilCat (talk) 17:20, 21 June 2023 (UTC)

Philip W. Lett Collection

I will be visiting Auburn University for a few days next week to see the Lett Collection. Philip Lett led the Chrysler design team for the XM1 Abrams. There are 30 square feet of documents and models of various projects Lett worked on. Please let me know if you need anything in particular scanned/photographed from this collection.

Ukraine to receive former USMC tanks

The page highlights reference to an article by David Axe in Forbes that the tanks going to Ukraine are former USMC tanks, specifically equipped with the USMC Firepower Enhancement Package (FEP). I believe former USMC tanks had DU armor, and providing M1s with DU armor to a foreign country would be a significant deviatioin from former US policy. Even the Australians got M1s without DU armor. I've only found reference to this in the Forbes article, and have written David Axe for clarification on his source.

I do not know if the FEP could be added to older M1A1s in stock, without significant time and work. I do know that the tanks pictured in some articles as the "M1A1s bound for Ukraine" have US Army-model smoke grenade launchers, but these are readily swapped. The .50 cal mount does seem to look different from Army M1A1s, but I have seen US Army M1A1s equipped with what I believe were USMC variations on the M1A1 mount, complete with a camera for the tank commander. This was at NTC (11th ACR/OPFOR) in the last 5 years or so. Vasky22 (talk) 18:02, 13 November 2023 (UTC)

David Axe replied and linked a different Forbes article that specifically notes that the M1 tanks going to Ukraine will not have DU armor. https://www.forbes.com/sites/davidaxe/2023/01/27/the-tungsten-m-1-how-ukraines-tanks-will-differ-from-americas/?sh=5fbcf13726b3 I think this should be noted that apparently these USMC M1s didn't have armor the equivalent of the US Army tanks, and that the Ukrainians are getting tanks that are roughly the equivalent of M1A1s sold to Australia and Iraq and Morocco. Vasky22 (talk) 17:47, 19 November 2023 (UTC)

• The US supplying the older M1A1 tanks is covered in the Operators section in the Ukraine entry already. -Fnlayson (talk) 19:03, 19 November 2023 (UTC)

Where are they getting the price per unit?

The linked citations are either extremely outdated (1990) or does not have a price at all. Diator (talk) 00:41, 14 January 2024 (UTC)
