As far as I know no transport unit will shift this & a couple of other SAMs as they are to large. Makes sense unless its on a dedicated vehicle the setup is to long, however all should probably really be untransportable or vica versa.
When playing late US you either have static SAM defence with radar capable of attacking standoff units or mobile all without radar.
It is a problem the game has Radar SAMs are important if you want a half decent chance vs standoff attacks.
