A simple module, something like Support Provider [Help] that you can sync with any unit you want; it'll get a S&D waypoint to the position you send them to (similair to how the other support providers work) just point and click using the menu and your mouse.

It'll also work for any addon vehicles that do not have the BIS weapons that the other Support Provider modules demand; for example I just tried using the Support Provider CAS [Bombing run] with an addon jet and it doesnt work.
