There’s an app for various Russian surface-to-air missile launchers:
After the collapse of the Warsaw Pact, the Hungarian amateur surface-to-air missile community—yes, there is a community for this—got access to detailed documentation on how to operate the country’s various, decommissioned Soviet-made SAMs. The sleuths also got into contact with some of the out-of-work operators and came close enough to photograph the instrument panels.
Put it all together, the result is a free simulator—known as SAM Simulator—that is a close approximation of the real thing. There’s no Buk missile launcher. But the 2K11 Krug is available. Both the Buk and the Krug use semi-active radar homing missiles.
These things were designed to be used by young conscripts, straight off the collective farm.
