It is possible to flatten a mountain to sea-level, build a military HQ, and then remove the grading so it is impossible for an attacker to reach and damage it.
There is a good example of this on Tail V, a base named "dEaD FOx".
I detonated a bomb on surface before realizing how far down the actual building is.
The building you can see is an airport that is next to the crater. The actual military HQ is deep deep underground below the crater. You can only ever see it by clipping into the ground.
I requested that Mr. Mortius remove his crappy exploited base from my homeworld. So not sure how long it will stay.
