If in a context where working with allies seems not probable, manipulating enemies is possible. I'm more thinking of anarchists that are disconnected from horizontal relationships, including others that identify as anarchists and they only want to do clandestine activities.
Tricking guards, bosses and co-workers to allow access may need the help of others. Also if someone possesses a skill that would be useful to a clandestine activity, it may not seem important what that person's identity and allegiances are.
I'm not talking about the world of professional militancy here, more of an example of a covert anarchist, like some of the whistleblowers for WikiLeaks, some of which held some rudimentary anti-authoritarian views despite being part of the military.
Also throughout history the workforce, including the military, there are always individual saboteurs that take their disgruntlement out on their employers. They might otherwise hold views that the left would cringe at, but they have no desire to be sung of as a hero and might even self-identify as an asshole. Anarchists can participate in these types of activities as well and with these kinds of individuals.
The problem is more along with message. Is an anarchist message getting out through these actions or are these actions just occurring without any responsibility being taken for them? Anarchist individualists tend to impose their views where they can and I'd imagine a bunch of rude boys (let's call them manarchists) wouldn't give a shit if the chaos guy of the group attributed their paths of destruction to an ominous anarchist cell name and wrote a manifesto threatening more of the same and explaining why they are doing the attacks.
One of the main problems with the present anarchist milieu is that it has adopted too much liberal and leftist cultural norms. This includes the post-left. It is as if every anarchist has to run a leftist moral gauntlet to deserve the title "anarchist". They can't come from a simple rejection of government, religion, school and/or work. Many anarchists participate in systems of control over students, as teachers professors, academics. Those that don't hardly present much of an argument against it. Then there are the courts that anarchist hold, thinking they can resolve things as mini-states within the "community". It is all a bunch of nonsense ran by overgrown children, the entire anarchist milieu is. To me, anarchists might do well to start from the beginning. Pick the base institutions are our enemies. Government, church, work, school. That's good enough. Now find accomplices to aid in the sabotage of these institutions, humiliate their leaders and loud personalities, and weaken those forces that defend them. End activism.
