Under the assumption that you drive away the enemy light troops and attack from the flank you might attempt a go at the sarissae.I have reservations if you could cut the reconstructed thick shaft of the sarissa that I have used.Why waste a blow when the pikeman's stance offer good targets to the neck or you can cleave limps instead.

That's the way I'd see it. Operating on the flank - likely in concert with cavalry - and creating mayhem in the more "open field" nature of a broken flank against the ememy's light infantry. The obvious attack route would be the phalanx's exposed flank after its suppport infantry had been broken open or cleared.

Again, a great weapon for the "hamstringing" of enemy cavalry one might think.
