You are the commander of the China Special Forces and Reconnaissance Company of the 13th United Nations Force Intervention Brigade, based at Minot Air Force Base. Your location in Dakota is part of West Canada, whose government you do not formally recognize; but you have an agreement with them authorizing your presence. It is March, and the raiding season is underway; three shotcallers leading 1500 men are making attacks throughout the territory for loot, ransom, and to project terror across the region. (Compare the Nigerian bandit conflict.) You face a few challenges with your current mission...
- If you stick to your agreement with the Dakotans, you are not authorized to use lethal force except in self-defense.
- Your mission (from the UN, at least) is to "neutralize and disrupt" the raiders that enter Dakota. You can arrest them or use non-lethal means to repel them. However, if you arrest them, you and your family will be targeted for merciless retaliation.
- The raiders are part of an immense empire covering all of southeastern North America, centered near the former Washington D.C. The borderland area of Dakota is considered rather sparse pickings, and faces a high risk of military reprisals. Local shotcallers violently resist the arrival of competitors from their own empire. However, if raiders drop out of the local trade, they will be quickly replaced by others seeking the same opportunity. An all-out war with the raiders will mobilize the Empire, which had been avoiding just such war -- the survival of your base will be in doubt. (Note that your fellow peacekeepers have already removed all nuclear capabilities from the base)
- You have been mulling over methods of unconventional warfare, and have been given a green light by the higher-ups on one contentious issue: the use of insects will not be considered an attack with a biological agent in contravention of the BWC, provided they do not reproduce. In that case they are simply trained attack animals, like war dogs or war elephants.
Given these constraints, you have had a strategy meeting at which the use of lice has been proposed. These lice are not lethal, do not produce or carry any prohibited chemical agent or biological weapon (assuming current treaties roughly apply), and they do not reproduce. They may be bred en masse prior to sterilization, and genetically modified to be unusually obnoxious ... even for lice. You want them to discourage and disrupt the raiders, but you do not want to suspected for their presence or characteristics. What is the most effective way for your company to employ war lice under these conditions?
P.S. the tongue in cheek answers are much appreciated. I should have mentioned this is the same scenario as the scythe bicycle. I'm aiming for a world much like our own, balancing stark realism and implausible inanity in equal measure.
