Back in the 50’s the idea of lobbing troops and cargo around the world with rockets seemed not altogether unreasonable. US Transport Projects #1 illustrated a battlefield troop transport based on the Redstone missile; US Transport Projects #2 illustrated a scaled-up project for the same sort of thing using a Jupiter missile. In the 1960’s, Douglas scaled up the idea to use a ROMBUS SSTO to launch 1,200 fully equipped Marines halfway across the world (as seen in USTP#4), and Convair studied a similar idea at the same time based on work done on their NEXUS/Post Saturn designs (as seen in Aerospace Projects Review issue V3N3). In the early 21st century, “HOT EAGLE” was a spaceplane concept for hypersonic rocket-launched troop transport (seen in USTP#5 and USTP#6).

It turns out that the idea is still alive, thanks  in no small part to SpaceX.

Pentagon wants SpaceX delivering cargo around the globe — and a live test could come next year

The goal isn’t small… 80 tons delivered anywhere in the globe inside of an hour. Falcon 9 could not do this; this would seem to be a job for Starship/Superheavy. *If* SpaceX can get that system running for their hoped-for cost of only $2 million per flight for an orbital launch, then this would seem entirely practical. $2 million to transport 80 tons seems a bit steep, but given that it would be used for special operations, it might be a bargain. It’s quite possible that the Starship to be used would have to be quite different from the standard Starship, even from a Starship used for point-to-point commercial cargo and passenger service. The landing gear would need to be improved, so the craft could land on uneven and unimproved terrain; it would need defensive systems from ECM to flares to chaff and perhaps even powerful defensive lasers.  Given the likelihood that the Starship would not be recovered, it might make sense to split it into two parts: a stripped down propulsion section and a cargo lander that is basically just a low L/D payload shroud that comes screaming in and lands with chutes and braking rockets, splits apart and spills out all the goodies. Nothing of value left for the enemy to scrounge up, just sheet metal.
