Powell's U-2 shoot down in 1960 is the "easiest" mission for SA-2F with V750-VU missiles. I consider that a tutorial. They provide a comprehensive documentations regarding the systems, from basic (normal acquisition, electronic warfare, and terminal guidance switching) to advanced (launch methods, masking, etc).
I finally managed to kill the pesky U-2. They are slow (about 160 m/s), flying at 22,000 meters, my V750-VU (SA-2 Guideline mod.1) killed it with the first shot, the warhead exploded 65 m away from the target (barely inside the lethal radius).
Russian SAM systems are confusing enough.
In the west/NATO, CMIIW you army guys here, they have a single type of missile for a system, isn't it? For example, a Starstreak battery will consist of just the missile launcher (the Starstreak) and the peripherals (radar, fire control systems, and whatevers -generators, comms, etc). So, can I conclude that the west defines a SAM system by the missile it fires? So, a PATRIOT battery will fire PATRIOT missile, be it PAC3, GEM, GEM+, and else... as long as it is from the MIM-104 type.
But in Soviet Russia, in seems the systems are just a system, they can guide and launch many types of missiles, what probably defines a system is the fire control system, not the missile or the radar. Some system like 2K11 Krug (SA-4 "Ganef"), 9K33 Osa (SA-8 "Gecko") and 9K330 Tor (SA-15 "Gauntlet") only fires 9M8, 9M33, and 9M330 family of missiles. They are TELAR systems, a complete package in a vehicle.
But we have SAMs like S-75 (SA-2s), S-125 (SA-3s), S-200 (SA-5s) and S-300 (or S-400). They can have many kinds of radars installed, like modules which you are able to switch between one and another, depending on your needs and the capability of each radar. Then, some of their systems are TELAR (esp. the S300), which means it can launch and guide missiles independently from the installations (making it very mobile), but with limited capability. The missiles are also various for each systems, Wikipedia listed at least 11 types for the S-300 systems, such as the 9M83, which rivals the PATRIOT and 40N6, which outclass PATRIOT.
Confusing ey? When we play normal games or watch Hollywood movies, we are just being told "we have SAMs!!!" "It's SA-2!" Well, incomplete. What missile did the battery use? What radar? What systems? What FCR? Some V750 missiles have more range than the others, some are just mere 26 km, but some can reach up to 66 km, some are maneuverable, some are not, and they are launched from what Americans only identified as "SA-2A/B/C/DE/F" sites, which are distinguishable from its radar and modernity.
