There seems to be a lot of testing new applications for weapons like the Hellfire.... brimstone instantly comes to mind and from what I found online was the Hellfire is cheaper to build than either the Brimstone or the Javalin so ground launch vehicles could very well become reality in the near future and both the Brimstone and Hellfire have a greater range than a Javalin but the Javalin is, of course, man-portable
There are all kinds of old tank / APC hulls in storage that could be adapted to be missile carriers
Or just adapt the helo mount for vehicles would seem doable
