Here is a thought about a potentially effective counter-recruitment tactic...
What if military-aged persons contacted their local recruiter and feigned interest in exploring a military career?
The person would talk to the recruiter, politely listen to the recruiter's presentation, make appointments and not show up, reschedule and show up, ask questions, take tests, remain polite but noncommittal, ultimately decide not to enlist.
The whole point would be to waste the recruiter's time and energy. An hour spent recruiting somebody who is not interested is an hour NOT spent recruiting some impressionable teenager who may be receptive to the recruiter's deceptive claims and imagery.
If enough persons do this, it would clog the recruitment system, demoralize the recruiters, and obstruct the war machine at its most vulnerable point.
Ecrasez l'infame!
