But there's interesting implications for green technologies though that would interest military scientists. The green revolution could lead to improved military technologies that would allow a superpower to gain superiority over others. If someone were to conjure up a green or even nuclear energy technology that's nearly as cheap(er) and safe(r) as oil to produce and is renewable; they wouldn't have the same logistical problems as a military depending on oil would. There's still the issue of munitions but without fuel demand, you could dedicate all logistics to essential supplies and munitions instead.
But if you want to go into future tech, developing a working re-usable rail gun would allow a unit to just carry coin sized objects to fire at a target at hypersonic velocities, eliminating the need for specific munitions, all you'd need is conductive metal. Then if you want to go to very far future tech, developing a weapon capable of ionizing air into a deployable plasma projectile well as remote controlled units (or primitive AI), you could eliminate the need for supplies altogether, and even not have soldiers on the field at all. Those aren't green technology related, but green technology with all those combined would create an almost unstoppable army.
I'm surprised that the military isn't at least very interested in developing green technologies that I'm aware of.
