So I just looked this up the 2017 footprint of the US army which I think accounts for more than half the worldwide military budget around the world was ~60 M tonnes. The numbers for bitcoin vary between 20 M and 60M per year (and are increasing). So both bitcoin and the US military are on the same order of magnitude.

Now regarding you imply that we should worry more about the emissions from armies than bitcoin, why is that an either or question? Yes we should worry about both wastes, but they are on the same order of magnitude. Moreover there is no evidence that bitcoin does reduce military spending or emissions, so again not making this an either or question.
