commander support call alternative

i think a modern alternative to the field glasses would be fun; after over 700 support calls i don´t have much difficulty placing the calls right, however planning them on an electronic map like you would do with a tablet these days would be cool.
you could put the trajectory and angle on a strafe, and you could set targets faster that require a lot of movement now (e.g. sitting in the hotel on coop/security precinct you have to move out into the street and back in often if you are on the objective and want to it right).
this equipment should, of course, come at a high price so that you may be left with a sidearm only ...

There has to be risk. Can't have people sitting in spawn calling support.

@mlb7 that´s easy to accomplish; spawn areas are dead spots as most buildings too ... 😉
