As Jack leaves the scene of the shootout in the Greek residence (55m30s), he heads down the stairs, turns into the market promenade, passes a Flautist, and a woman in a dark mauve top. As he exists the market corridor, the same woman is seen sitting at a table with two friends in the foreground.
03:52 - The year is 1969 and there is a parked Lada Niva in front of the laboratory. According to Wikipedia, the Lada Niva production began in 1977.
In S3.1, Yuri Baskin [Michael Epp], the defecting Russian physicist, describes the covert nuclear weapon thusly, "Sokol is not high-yield; it's small, only three megatons".
That means Sokol would rate among the most powerful H-bombs the United States ever fielded, the biggest having been the W53 warhead atop Titan II ICBMs - Sokol's yield would be about 200 times the energy released by the atomic bomb exploded over Hiroshima, Japan. No doubt the writers meant for Yuri to say, "kiloton," which is 1/1000th of a "megaton."

The horn of the Iveco fire truck sounds like a typical American truck horn.
When Luka and General exit administrative buildings there is a Vaz2103 and a Niva cars on the left, both were not produced at the time. Both entered production in the 70s, also the event takes place in 1969.
At the beginning of S03E01, the closest car to the building is a Lada Niva. This car shouldn't be there because first model was presented in 1977, 8 years after the story begins.
The opening scene takes place in 1969. When when Zoya hands Ryan the SIM card she says the program was funded at during the fall of the Soviet Union, which would have been 1989.
Yuri Bashkin, the nuclear scientist, says the new warhead is "not high yield, it's small, only three megatons". Three megatons is definitely high-yield, that would make it twice as powerful as the most powerful warhead in the US arsenal, the B83, which has a yield of 1.2 megatons. Almost all of the nuclear warheads in use have a yield in the kiloton range, the US is planning on retiring the B83 from active service and keeping it in stockpile, at which time the most powerful warhead will be the B61, which has a maximum yield of 400 kilotons.
