Boris says three out of four MRLs are inoperable, each has 12 rockets loaded.

Quotes from the book:

Danila's letter, chapter 15: “Part Number... tunnel... D6... intact installations... up to 400,000 square metres... a water fountain... not in good working order... unforeseen...”

Danila's letter in russian version mentions BM-30: «Часть №… туннель… Д6… уцелевшие установки… до 400 000 кв. метров… смерч… неисправно… непредвиденные…»

Smerch was translated as "water fountain" and military unit as "part".

Miller's dialogue with Artyom: “They kept it for themselves... They didn't tell the military. Not a surprise, really... Show them something like this and they'll immediately take it as something old”, Melnik mumbled indistinctly while Artyom patiently awaited some explanations. “But did they really overlook it? It's faulty... Well, let's assume it is OK... That means they must have checked it!” “Can it really help?”: Artyom finally couldn't stand it. “If everything written here is true, then there's hope”, the stalker nodded. “What's it about? I didn't understand a thing.” Melnik didn't answer right away. Once more he read the message to the end, then thought for several seconds and only after that did he begin his tale: “I had heard about such a thing before. Legends were always flying about, but there are thousands of them in the metro, you see. And we live by legends, and not by bread alone. About University, about the Kremlin and about Polis you can't make out what is the truth and what was contrived around a bonfire at Ploshchad Ilicha. And so you see... Generally, there were rumours that somewhere in Moscow or outside of Moscow a missile unit had survived. Of course, there is no way that could have happened. Military facilities are always the number one target. But the rumours said they were unsuccessful, or they didn't see it through, or they forgot it - and one missile unit wasn't damaged at all. They said that someone had even walked there, had seen something there, and, allegedly, the installations were beneath a tarpaulin, brand new in the hangars... True, there's no need for them in the metro - you can't reach your enemies at such a depth. They stand - well, let them remain standing.”

Miller's dialogue with Artyom on D-6: “A salvo of twelve rockets with high explosive fragmentation warheads covers an area of 400,000 square metres”, Melnik read, finding the necessary place in the message. “Several such salvos from the Botanical Garden will turn them to dust.” “But you just said that these are legends”, Artyom objected. “Well, the Brahmins say they aren't.” The stalker waved the sheet. “It even explains here how to find our way to the location of this military unit. True, it also says that the installations are partially inoperable.” “Well, just how then do we get there?” “D-6. It mentions D-6 here. Metro-2. The location of one of the entrances is indicated. They maintain that the tunnel leads from there towards this unit. But they stipulate themselves that unforeseen obstacles may arise on trying to get through to Metro-2.”

Miller's instructions, chapter 18: “You take two protective suits, we have four left, and we don't know what it will be like there. There's one radio for you and one for us. Now the instructions. Go to Prospect Mir. They are waiting for you there. I have sent some messengers.” He looked at his wristwatch. “In exactly twelve hours go up to the surface and look for our signal. If everything is OK and we are on the air, we'll move to the next stage of the operation. Your mission is to find the best way to the Botanical Gardens and then to get up high in order to help us direct and correct the fire. The “Smerch” has a limited destruction area and we don't know how many missiles are still there. And the gardens aren't small. Don't worry”, he said to Artyom, “Ulman will be doing it all, you are there as company. We have use for you too, of course. You know what these dark ones look like.
