Wait i think its a GREAT idea to trundle around up and down hills for hours to have a radar that shows which base is being horded after the field dar is down, I mean I would totally spawn it out to a spawn point and get killed by a m18 multiple times to show the same info already avail in game.

Why drive around? If field radar is down, just find a place to hide and provide useful info for guys in the air so they can go after bombers, etc as they would if field radar is up? Field radar down would simply create a need for someone to help out their team this way... esp if they are on the phone or otherwise unable to concentrate on fighting or a few minutes.
If there was a need for this capability in WWII, why not enable it in here also for the same purpose?

How many times have you benefited from nearby CV radar when field radar was out?
Also this would provide an airborne radar solution behind enemy lines. Which was very important to pilots during the war.
