I'll put it to you this way: all the militaries of all the countries in everything they do, are responsible for 6% of the CO2 emissions. I'll let you figure out why explosions alone were not mentioned at all.
I have quickly googled that statement and all I see is pre-02/24/22 data. I am sure the percent has changed significantly from the good old times.

There is nothing about “military engines” or “military supply routes” or “military explosions” that leads anyone to believe their impact would be any worse than their civilian equivalents, and even if they were, you still have to prove that they are so much worse that even their limited activity compared to the normal economy must be given priority attention.
The burden of proof is on the one making the claim, not everyone else.
When you're done with that search, look up volcano explosions on land and under the sea, and compare them to the explosive power of a missle.
When you have a bleeding cow, you can solve the bleeding issue and keep the cow alive, while completely ignoring the mosquitoes "relentlessly draining" its blood.
