I understand how energy weapons are unable to penetrate any atmosphere of 1 or more, and how their damage drops off for <1. I was though under the impression that meson beams ignored this and thus could be used, however when I am trying to target some ground forces to soften things up before my own invasion arrives, I am met with a message that mesons are precision weapons and cannot target ground units or population. Does this mean then that the only time any beam weapon of any kind can be used with regards to planets if from a ground based PDC firing outwards at a ship using a meson?
If this is the case then will using size 1 missiles against ground units cause collateral damage to the population, infrastructure, and planet (rad & dust)?
