Planning is rather superfluous unless you know who the enemy is. Calling it a “horde” doesn’t work without an attributive adjective, like “starving horde”, “(minority) horde”, or even “federal agent/brownshirt horde”.
A disorganized horde is rarely even functional outside its own neighborhood, the most recent example being the Rodney King rioters who ventured into the Korean neighborhood to wreak havoc. This worked once. The next day had they tried it again, they would have met a civilian Korean light infantry and reenacted the Northfield, Minnesota Bank Robbery, except on a grander scale. A lot o’ dead rioters.
A starving horde is kind of a non sequitur in America, as America has always had an overabundance of food, and even in the worst of times has scraped together enough to share.
Perhaps the most likely horde would officially be called “The FEMACorps horde, a subsidiary of the AmeriCorps horde.”

And I’m sure the intent is to issue each one a Glock .40 and 1000 rounds of ammo and tell them to go forth and control and dominate. The end result being a whole lot of dead FEMACorps brownshirts.
