Was playing against someone that I hadn't played against before. I had unloaded some guys into forest (out of LOS) and moved deeper in. Encountered no-one on the way. Guys were not adjacent nor did they advance in a straight line.
Enemy did not have air support, so I was somewhat surprised when both units were accurately mortared, suppressed and then attacked by enemy units coming from different directions - straight onto my guys.

Then it happened to another unit in another forest the next turn as well.
Must've been heat-seeking mortars, right? Or perhaps an opponent with super-vision.
Puzzling...
