This asset contain two hierarchically linked models of Russian SA-11 Gadfly/SA-17 Grizzly ('Buk' in Russian designation) TEL/loader in stowed and deployed positions. This help understand, how the model should be looked in these positions.
The SA-11 Gadfly look similar as SA-17 Grizzly. The last is modernised version of SA-11 actually, with new type of a radar system and improved missile. But all these differences cant be viewed by the eye. So you can use this model as both of them.
