and apparently that is what they did here. Looking at it I think I can tie down my initial problem with it: that there were 10 units involved that had to be directed; and for some reason I was thinking that each of the packs each of those poor suckers was strapped to were receiving individual steers and control inputs to keep them in formation. Certainly after having read the events of 6, plus our discussions here, have me saying "Dude, its cool, just believe the author has a good grasp on HIS DAMN STORY and let him tell it his way. You know this dude, trust him already"
