>Ships are also not nearly as prevalent as they were in WW2 (as international capable jet transport didn't really exist then). Vietnam used troop transports, but I don't think Desert Storm used much beyond airplanes.

As someone who supported loading a whole division's worth of vehicles onto ships during the Iraq war, I would like to know what you're basing that on. Sure, the people go by plane, but the people represent an overwhelming minority of the total tonnage moved to deploy a unit.
