I was always a big fan of this one, myself, especially at head/neck level.

For the "initially unarmed", it's good to station a couple of people near the wire with spears (steak knives attached to broom handles). Spear the thug, take his weapons, disappear

The beauty of this situation is that the forces involved. The military and IRGC have backed away from any responsibility to do crowd control or internal policing a few demonstrations back. This leaves only the Basij morality police, and actual cops, to do the stomping.

The Iranian students and the sympathetic general population may only be armed with knives, traps and homemade explosives, but those can go a long way when your enemy won't be showing up in tanks. Lighly armed mobs clashing outside their grand mosques should have the mullahs more than a little concerned.
