I, too, was wondering how many military personnel a brigade or "unit" includes...
This Wiki Answer wasn't much help:
How many men in a military brigade?
In: Iraq War
The modern military no longer uses set piece units at levels above battalion size. They customize units to accomplish a specific mission, adding forces like engineers, intelligence units and detaching armor or artillery. A brigade was once somewhere between a regiment and a division. Today it could be less then 3000 men, or even twice that number.
Topic of how many in the various military units is discussed at this forum: http://www.candlepowerforums.com/vb/...ad.php?t=19511
There seems to be no correct direct answer, but the best I could tell a brigade **may** be up to 4,500 personnel. That would hardly be enough to do much damage, unless they are going to "tour" various large cities for the country's benefit.
But oh yeah, I think it's coming one of these days/months/not too distant years...
