If you’re a military unit about to get wiped out by an enemy force due to running out of ammo, I imagine getting 100 tons of ammo in 1 hour vs in 19 hours would be a big difference?
The scenario where you have access to a space launch system, and an LZ at the front, and abundant supplies on the opposite side of the earth, but your logistics have failed to keep supplies in theater doesn't exist.
Forces that run out of ammo don't have access to cutting edge ICBMs is a rule that I would bet money on.
