I remember the first time I learned this lesson. Cluster bomb called in, killed the other 3 of my team. I learned it again on the 120mm HE, and the 380mm HE. The mortar sentry.

Bouncing a 500kg off something right into your face will never not get a hearty laugh from me. We can send beacons into space, but we can't mark a location without being in dangerously close range.
