It might be something or not, but last week on one of the maps I thought I noted odd radar behavior at two friendly bases with overlapping radar rings also overlapping the bases (and their radar towers) themselves, both within I believe the same major map sector. The SW-most field was under constant attack from an enemy fireld just to it's own SW with nothing in range of the NE-most field's dar but still constantly setting it off until some enemy destroyed the SW-most base's radar tower and had been "vacated" from the premesis of the overlapping NE-base's radar circle.
I originally dismissed it for a sneaker at our NE-most base, but after searching the town and field and all nearby barns for a bit of time (no enemy vspawn was there) I realised nothing was there so it was probabley someone hiding. After the radar was downed and the enemy con cleared and then it finally stopped flashing - that I thought was odd.
