Wish I could take the credit for finding it, Red. More than that, I wish I could give proper credit to the guy who did, but memory is failing in my old age ( or maybe had something to do with it). I do remember him saying what tipped him to it was a unit of light horse frontally charging a phalanx downhill and taking zero casualties in the initial charge. He concluded that the spear doesn't really exist, only the one set of spear points, and the animations weren't up to positioning those points relative to local ground level. However, he did use this knowledge to document a nifty exploit. He strung a single or double line of archers just in FRONT of his phalanx line, inside their dead zone, set all units to stand ground, and the archers were able to fire at point blank range while the phalanx protected them. Kinda confirms that the second and third rows are just for looks.
