Dear All,

OSA SIM will not arrive, at least until the end of 2013, at its best.
Currently Im learning its operation and capabilities, and designing the SIM screens.

Im happy to answer questions about this remarkable system (last single digit SAM), while Im still building up my knowledge.


Originally it was planned as a cheap alternative system to the KUB, having full autonomous operation per vehicle.
When the KUB become available during the 70's, it was fielded in the WarPact at both tank/mechanized divisions.

At last, when the OSA become available in the 80's, WarPact armies started to swap the more expensive KUB regiments with the OSA!!!
(GDR - 2 regiments, Czechoslovakia - 1 regiment, Hungary - never fielded)
The reason was that a KUB regiment had only 5 target channel, utilizing 25 tracked vehicles...
... on the other side, the OSA regiment had 20 target channel (4x of a KUB) with 20 wheeled vehicles.
