Greeks always fought outnumbered?

[Macedon]

Not sure where you are getting this from. All that a hoplite needed to be a hoplite was an aspis and a dory. Its clear from the Anabasis just how little heavy armor the mercs had. Xenophon's march shows that obviously a hoplite army could march very far in hoplite kit. Unless hoplites ate more than Sarissaphoroi, I don't buy your argument. The aspis was surely a burden, but no more so than sarissa. I've read that during the 30yrs war pikemen regularly chopped down their pikes or simply "lost" them because of the hardship of moving them.

Polybius also stressed the strain of bearing the sarisa during the march (18.18.3.1).
