If by "harass the military" you are referring to the passage in the above article which talks about "blockade
the armed forces' joint headquarters at Northwood, in north London" then, in my not so humble opinion, the action is directed towards the right target--the decision-makers and not the soldiers. I've have a problem with harrassing soldiers for the same reasons you allude to, however I don't read anything like that in the article.
