I wish radar had more useful features, like being able to get an estimated altitude of a con. IIRC the radar used in WWII COULD get an estimated, if imprecise, altitude anyway, so it's not like it'd be inaccurate.
As it is right now, if a bunch of guys pop up on the map near a base, the defenders have a heck of a time knowing if its alt-monkey cherry-pickers or buffs in the stratosphere, or if it's mid or low or whatever other alt.
