China has been the largest ghg emitter for the last 20 years, and currently emits more than twice as much as the us. Gdp spent on defense is similar as a fraction of gdp (slightly more in the us). So realistically the Chinese military is by far a larger emitter of ghg than the us military.

So the issue is under regulation, yeah, agree on that point.

Sounds like the only reasonable solution to the problem you raise is that the part of our government that's responsible for defense should be put under the seperate part that is responsible for protecting our environment instead of being exempt. I can't see any other real way of resolving that issue can you?
