Even when teleportation is "problematic" or unusable for orbital drop scenarios, I've seen RP where Mindy simply form a CFS bubble and zip down through the atmosphere in a totally controlled descent. Trans-atmospheric operations are no different for Mindy than moving through space, whether it's by way of teleporter, CFS, or using regular propulsion. The battlescape in power armor combat is not limited or separated by whether the Star Army is fighting on a planet, in the void, or on a ship. All of these things are one flowing concept, and are nothing more than terrain features that are encountered in the vast expanse of space.
