Yeah, I meant the Ranger operation of Point due Hoc in preparation of D-Day.
And the shuttle/stealth missile was meant as an abstraction/justification why troops should be able to land on a planet while being launched some distance away from the planet. They could take the form of ship techs/modules on ships in order to enable such landings.
One could add different levels of ECM/stealth for such modules, making them harder to track/shoot down if you want to make it more realistic and add another layer of defense. If you want to raise the costs for such things having another tech for increasing drop ranges might be a way.
One enabler tech (maybe including a higher number of troops at higher levels for a higher success chance), one range tech, one ECM/stealth tech. In addition to the cost for the modules and the troops this might present enough of a hurdle were this is just one more option, but not necessarily the "best".
Essentially I just like the idea to have another option (even if it is very expensive) than blasting the STOs, shielding/armoring huge/fast drop ships or being willing to risk troops/ships by ignoring the STOs.
