Several (6? 8?) years ago, in the possible lunar base discussion, I had suggested that the lunar modules should be buried into trenches, so the first thing to deliver is a heavy bulldozer to dig out these trenches and then cover them with ground.
They were laughing and suggesting to ram the bulldozer into the lunar surface at several km/s speed, so the trench will appear without digging,

Several years later I was suggesting a sandbag fortress to reinforce the pioneer lunar outposts.
Nobody took this seriously. Well, well...

P.S.
Btw, my next suggestion on the deuterium fusion plant and superheavy launchpad complex is still on the table.

Btw the Project Horizon base was beginning from the several lunar tractors delivery.
