A Holocam could be used.

And of course the Trianing Remote like the previous person here mentioned...

In General, the Rebelion doesn't seem to have any probe droids specifically to them as the Imperials do.

Canadiens, that's an idea I just thought of. You could have a map where the Rebels invade a Imperial testing facility and the Imperials must use the wacky weapons and vehicles they have at hand.

Also, remember those TIE prototypes from Rebel Assult II that were able to cloak?  Just mess around with mesh transparency for each LOD for the TIE.  For instance, have transparency at 90% for far away, and as the LOD level becomes more detailed as the ship is closer, have it less transparent and easier to hit.

An X-Wing raid on their production facility would be a great map idea.
