Electromagnetic Rail Anti-Material Rifle
This is the heavy weapon system known as the ERAMR (Electromagnetic Rail Anti-Material Rifle), or by the troops that use it as "The Big One," although it is disputed if this is due to the size of the weapon, the damage caused by impact, or the massive power requirements.
When carried by standard infantry, the weapon requires a crew of two. One person carries the six foot long weapon itself, which fortunately folds at the base of the barrel for ease of transport. The other transports the ammunition and the massive battery packs, each of which measures 25cm long and 15 cm wide. These packs are disposable and cheap batteries, but the weapon can be used with larger, higher capacity batteries. As such, the other, more common means of deployment is with a suit of power armor. Soldiers who use it with suits of powered armor must use specially modified armor to cope with the ridiculous power requirements.
Rapid fire can feel natural at first, due to the lack of conventional recoil, but such behavior is drummed out of trainees within the first weeks of training, as taking too many shots too quickly can empty the battery quite rapidly, and leave a soldier in a powered exoskeleton laying helpless on the ground, a frozen metal statue. However, the ERAMR is functionally identical to other railguns in use, albeit much, much larger.
The unique part of this weapon is the ammunition. The caliber of the weapon (15mm) permits much larger and more complex rounds than can be fired from a standard railgun. The two most common ammo types are CPTP rounds and standard kinetic penatrators. The CPTP (Copper-Plasma Tipped Penatrator) round is made of a hollow tugsten body with a copper head. The hollow space in the body is filled with argon. When the round is energized by the magnetic rails, the argon becomes a plasma, generating a massive amount of heat and pressure. The tugsten body of the round can withstand this pressure, but the impact breaks the thinner tugsten wall between the argon and the copper. This creates a flash of plasma and a molten copper penetrator moving at hypersonic speeds. The CPTP shell is notorious for the purple flashes of argon released on impact, and the massive penetrating power of the copper penetrator has been known to shear through tanks. Indeed, many armored units will flee upon sight of the purple glare created on impact. However, the MRAMR can also fire a variety of more... exotic rounds. Among these are flechette cluster rounds, bolo rounds, plasma burst rounds, and so many more. A large enough barrel for use of SABOT rounds and a powerful enough weapon to fire incredibly heavy projectiles permits a nearly infinite variety of so-called "oddball" custom rounds.
The only downside to the ERAMR other than the size is the massive, twenty-foot plume of smoke and sparks that spews from the barrel on firing. Most ERAMRs are equipped with muzzle breaks, to vent the smoke to the sides, but it is still impossible to fire one in a subtle manner from close range. Due to this, most engagements are from far enough away that the targets cannot easily spot the sniper or return fire.

American, east coast, military family. I study small arms and ballistics as a hobby, now examining light vehicles also. I've hiked 50% of the Appalachian mountain range and I once used a fire extinguisher for an emergency.

"Gotcha. Well, a slight spoiler, but I am planning for a group in Siberia to be important later in the story, just not during this invasion. And they will have pretty good organization and tech/be Russia's heir. I'll have to get your help for planning it later, cuz right now it's still too spoilery to talk about."There doesn't seem to be anything theoretical about this particular conspiracy. The distance from Siberia to the Arkjut village appears to be as far as Tenzin has traveled since his family was killed. The deathbots may travel faster than a Tibetan child with PTSD, but that still suggests the attack on Aegis was planned in advance. I wonder if Jane could win a fight with SOPCA.

NATO calls that "multiple rounds, simultaneous impact". It refers to tanks and mortars because most NATO grenade launchers are single-shot. I don't think the deathbot was far enough from Tenzin to use this idea, but it is possible he has used it before. On the map, it shows that Tenzin met Viktor in Novosibirsk. There is a chance he met Russians who knew how to use this trick.
If he did not learn how to do this in Russia, Jane may suggest it because his grenade launcher is suitable for it.
В NATO подобная техника огня называется "множественный выстрел, одновременное поподание". Этот термин используется в отношении танков и минометов, исопльзуемые NATO подствольные гранатометы однозарядны. Не думаю, что робот-убийца был достаточно далеко от Тензина, чтобы стрелять по нему подобным образом, но не исключено, что он владеет такой техникой. Судя по карте он встретил Виктора в Новосибрске, где, возможно, научился такому трюку от русского стрелка.
Или же Джейн могла описать ему эту технику - его гранатомет для неё подходит.

For GP-25 and GP-30 with caseless ammunition, there is a trick, when spare round is held in the shooting arm's fingers. It allows for a very fast reload. Master shooters can fire one shot on a ballistic trajectory, reload and fire the second one in a straight line with both grenades hitting the target almost simultaneously.
Для ГП-25 и ГП-30 с безгильзовыми боеприпасами есть трюк, когда запасной патрон удерживается пальцами стреляющей руки. Тогда перезарядить гранатомет и выстрелить второй раз можно очень быстро. Мастера успевают выстрелить первый раз по навесной траектории, а второй раз по настильной траектории так, что гранаты прилетают к цели почти одновременно.

Jane requests two grenades to kill the deathbot. It's ambiguous whether or not Tenzin actually hit the target twice because it survived long enough to dismember him. However, the artificial intelligence probably would not specify "two" if the launcher were only capable of a single shot.

Did Tenzin fire more than 1 shot from his grenade launcher? I can't seem to find that.

I think we may need forward plot progress before more nuclear reactor research becomes relevant. To quote from the "Lore" tab:
"I now understand why nuclear research stopped. I do not understand why Glaucus has never undertaken any research on nuclear energy. I can’t even find reference to any projects to clean up residual radiation in the environment, yet it is almost common knowledge that one of Minerva’s first missions was to clean the air and water around the base of radioactive particles to permit farming. Instead, I find a suspicious absence of any entry mentioning nuclear energy. Interesting. I shall have to investigate this further."
The obvious explanation is that Glaucus is already aware of safe nuclear power options, but deliberately avoids keeping any record of it. If I had to choose someone to ask about top-secret research, Thalia Gordon would be first on my list. Jane would be second, because she's already suspicious of Commander Kubek's tight security and it would be easy to manipulate her into espionage.
Regardless of politics and secrets, the reactor is relatively simple. It requires nuclear waste, which is abundant, and thorium, which is "abundant". Because few current reactors depend on this, there has been no large effort to find deposits of thorium. It's common in small amounts, but difficult to extract unless concentrated. The best source of thorium is probably the southeastern coast of India, but there may be closer sources in Russia. Current demand is satisfied because thorium is a byproduct of rare-earth metal extraction from monazite sand, which is also a viable source of helium and other valuable elements.
Glaucus may have their own motives for avoiding the topic of nuclear power, despite the fact Minervan territory is rich in radioactive minerals. Therefore, the most stealthy solution is to support increased mining efforts. The advanced technology used to keep Minerva secure requires rare-earth elements for sensitive electronics. Because Minerva is under attack recently, locating many potential sources is a wise use of time and money. Mine production may need to be increased to replace destroyed equipment.

In the Mirage prequel, the primary weapon is described as an autocannon, and it fires 20mm solid shells. However, this is inconsistent with Tenzin's weapon. The ejected casings are too short to be a modern 20x102mm NATO standard. My guess is that it's a modified version of the experimental 25x59mm, which exist but has not been standardized with any army. It is used in the Barret XM109, which could destroy vehicles 2,000 meters away in tests. However, it produced unacceptable recoil: 60 foot-pounds! For comparison, the Barret M82 fires .50 and only produces 36 foot-pounds.  By decreasing the diameter, the recoil is reduced. I think the projectile is also more streamlined to reduce air drag and extend range. It would still be very overpowered for infantry, and each magazine only holds 10 rounds of ammunition. Tenzin's weapon does not have a muzzle brake for some reason, possibly to reduce the total length. It's also possible Aegis deliberately allows high recoil, so none of their enemies can use a captured weapon. Tenzin's grenade launcher is not mentioned in the prequel, but it visibly doesn't eject spent casings. However, Tenzin does use rapid semi-automatic shots. This means the grenade launcher uses caseless amunition, probably stacked in the barrel. A similar weapon exists: it was developed by an Australian company that went bankrupt and sold the designs to a new company, DefendTex. China offered to purchase the design and the American Navy adopted it for testing.  |

From the discussion above: by von Neumann machine we mean not a single vehicle or production unit but a whole system that includes resource harvesters, production facilities and so on. The key trait of von Neumann machine is it's complete automation by an AI.

Машина фон Неймана как отдельная единица рассматриваться может только в масштабе всего небесного тела. Отдельные части, ползающий по поверхности небесного тела, летающие над ней, плавающие и бурящиеся сквозь него - это именно части общей системы. Какие-то из этих частей будут заниматься геологоразведкой, какие-то перевозками, какие-то будут обеспечивать связь, а какие-то производство необходимых машин, какие-то добычу необходимых ископаемых. Уж чего-чего, а банальных металлов после Коллапса нашей цивилизации потомкам еще не на одну сотню лет простого собирательства хватит. Вон в Сирии металлолома столько, что на Квейрис из него удалось рабочий МиГ-21 собрать. :eek: Фракции "Туркмены" из нашей игры на заметку. У них там реально может ко времени игры вполне рабочеспособная техника дожить. Только вот собирать ее надо будет из нескольких кусков, вероятнее всего. То есть знать, как собирать, а местное население с этим сейчас сильно не в ладах. Куда Минерва денется с подводной лодки, вон заглотили наживку, чуть ли не с поплавком: thedemonarchives.freeforums.net/post/2777/thread . Сейчас только нужно не спугнуть... |

Ooh, Glaucus could probable be convinced to fund research that both produces energy AND cleans up nuclear waste. You should write it up more, MG. |

С машинами фон Неймана вопрос не столько в возможности машины собирать себе подобное (в "Мираже" упоминается автономная сборочная линия, на которой, судя по всему, собиралась броня вроде той, которую использует Тензин), а в добыче необходимых материалов. Если нести все с собой, то какой смысл собирать что-то на месте? Если пытаться добыть все нужное на месте, то возникают вопросы геологоразведки и того, что залежей критичных металлов вообще нет поблизости.
А, да, и Минерва из принципа не использует ядерные технологии.
